The terms defined in DSP0004, DSP0223, and DSP1001 apply to this document.

The following additional terms are defined in this document.

##

autonomous profile

a profile that addresses an autonomous and self-contained management domain. For a complete definition, see DSP1001.

DSP1001 defines that in autonomous profiles, the central class adaptation and scoping class adaptation are the same. Thus, autonomous profiles cannot be scoped by other profiles. With the exception of this profile, autonomous profiles do not need to be referenced in order to be implemented, and can therefore be implemented alone. Autonomous profiles may reference component profiles and autonomous profiles (including itself) and may scope component profiles.

See also term "component profile".

##

central class adaptation

a class adaptation whose instances act as an algorithmic focal point for advertising conformance of a profile implementation to its profile. For a more general definition, see DSP1001. See also term "scoping class adaptation".

##

central class methodology

an algorithm for advertising profile conformance that uses the central instances of the registered profile as a focal point. For a complete definition, see subclause "Central class methodology". See also term "scoping class methodology".

##

central element

the managed object type modeled by a central class adaptation. See also term "scoping element".

##

central instance

an instance of the central class adaptation. See also term "scoping instance".

##

component profile

a profile that addresses a subset of a management domain. For a complete definition, see DSP1001.

DSP1001 defines that in component profiles, the central class adaptation and scoping class adaptation are not the same. Component profiles need to be scoped by one or more scoping profiles in order to be implemented, and can be implemented only together with one if its scoping profiles. Component profiles may reference autonomous profiles and component profiles (including itself) and may scope other component profiles.

See also term "autonomous profile".

##

Interop namespace

a role of a CIM namespace for the purpose of providing a common and well-known place for clients to discover modeled entities, such as the profiles to which an implementation advertises conformance. The term is also used for namespaces that assume that role. For a complete definition, see subclause "Interop namespace". See also term "implementation namespace".

##

implementation namespace

a role of a CIM namespace for the purpose of providing a place for CIM objects for which no specific namespace requirements are defined. The term is also used for namespaces that assume that role. For a complete definition, see subclause "Implementation namespaces". See also term "Interop namespace".

##

profile

a management profile, as defined in DSP1001.

##

profile conformance

conformance of a profile implementation to its profile, such that it satisfies the rules for full implementation conformance defined in subclause 5.2.2 of DSP1001.

##

referenced profile

a profile that is referenced by a profile that lists it in its profile references table. For a complete definition, see subclause 7.9.1 of DSP1001.

##

referencing profile

a profile that references a profile by listing it in its profile references table. For a complete definition, see subclause 7.9.1 of DSP1001.

##

registered profile

a profile to which a profile implementation advertises conformance. Before version 1.1 of this profile, registered profiles were termed "subject profiles" (now deprecated).

##

scoping class adaptation

a class adaptation that acts as an algorithmic focal point for advertising conformance of a profile implementation to its profile when using the scoping class methodology. For a more general definition, see DSP1001. See also term "central class adaptation".

##

scoping class methodology

an algorithm for advertising profile conformance that uses the scoping instances of the registered profile as a focal point. For a complete definition, see subclause "Scoping class methodology". See also term "central class methodology".

##

scoping element

the managed object type modeled by a scoping class adaptation. See also term "central element".

##

scoping instance

an instance of the scoping class adaptation. See also term "central instance".

##

scoping path

an association traversal path between the central class adaptation and the scoping class adaptation. For a complete definition, see DSP1001.

##

scoping profile

a profile that provides a scope to a scoped profile by defining a central class adaptation that is based on the scoping class adaptation defined in the scoped profile. For a complete definition, see DSP1001.

##

subject profile

DEPRECATED: The term "subject profile" has been deprecated in version 1.1 of this profile, because its meaning as defined in this profile was different from the meaning as defined in DSP1001.

Use the term "registered profile" instead.

##

this profile

# Description

## Collaboration structure diagram

DMTF collaboration structure diagrams show class adaptations (including association adaptations) and can express additional adaptation conformance requirements on an adaptation by means of role bindings (dotted lines) of collaboration uses (dotted ovals) that represent profile references and thus profile implementations. The names in a collaboration use oval that represents a profile reference are the profile reference name as defined in the profile reference table, and the profile name. The names on the role bindings of such collaboration uses are names of adaptations defined in the referenced profile represented by the collaboration use. These role bindings in the (informational) diagram are normatively defined as base adaptations of the adaptations targeted by the role bindings.

The following DMTF collaboration structure diagram shows all class adaptations defined in this profile, and all profiles referenced by this profile.

DMTF collaboration structure diagram

Registered profiles are represented by instances of the RegisteredProfile adaptation in the Interop namespace.

As defined in subclause "WBEM server requirements on CIM namespaces", the roles of an Interop namespace and of an implementation namespace can be assumed by different namespaces or by the same namespace. The diagram in Figure 1 lists one namespace role for each dotted rounded rectangle. In WBEM servers that support implementation namespaces separate from their Interop namespace, instances of these adaptations would be exposed in their respective namespaces. In WBEM servers that support only one namespace, instances of these adaptations would all be exposed in that namespace.

The RegisteredProfile adaptation is the central and scoping class adaptation of this profile.

The central and scoping elements of the registered profile are represented by instances of the CentralElement and ScopingElement adaptation, respectively, in the implementation namespace(s) of the registered profile.

If the registered profile implements the central class methodology, the ElementConformsToProfile association adaptation (between the RegisteredProfile and CentralElement adaptations) is implemented; otherwise, the registered profile implements the scoping class methodology and the ElementConformsToProfile association adaptation is not implemented. For a complete definition, see subclause "Central and scoping class concept".

If the registered profile references any profiles, the profiles to which the implementations of these referenced profiles conform are represented by instances of the ReferencedRegisteredProfile adaptation in the Interop namespace; these instances are associated via the ReferencedProfile association adaptation to the instances of the RegisteredProfile adaptation that represent the referencing profile. In addition, the ReferencedRegisteredProfile and ReferencedProfile adaptations may be implemented in the implementation namespaces of the registered profile.

The referenced profiles also advertise their profile conformance through an implementation of this profile. Because the referenced profiles of this profile are the registered profiles of those profile implementations, the ReferencedRegisteredProfile adaptation is based on the RegisteredProfile adaptation.

If the registered profile is a component profile, it has a scoping profile. Conformance of an implementation of the scoping profile to the scoping profile is again advertised by an implementation of this profile.

Because the central element of a scoping profile (of the registered profile) is the scoping element of the registered profile, the central element adaptation defined in the scoping profile is based on the scoping element adaptation defined in the registered profile.

The implementation of this profile itself is can also be advertised through a usage of this profile on itself; that is not shown in the diagram.

## Central and scoping class concept

### General

Profiles typically define constraints and behavioral requirements for more than one CIM schema class. The usages of CIM schema classes in the context of a profile are termed adaptations (see DSP1001). For an implementation to conform to a profile, each of the CIM elements for which the profile defines constraints and behavioral requirements needs to conform to these constraints and behavioral requirements. Since profiles also define which entities in the managed environment are represented by the model entities, conformance to a profile cannot only be limited to interface conformance (see DSP1001), but needs to include those mapping aspects as well. Therefore, an implementation conforms to a profile, if it satisfies the rules for full implementation conformance defined in 5.2.2 of DSP1001.

This profile establishes the concepts of a central class adaptation and a scoping class adaptation , in order for a client to be able to perform the following tasks:

- to find the CIM instances that conform to the registered profile, given the RegisteredProfile instance representing the registered profile
- to find - for a given CIM instance - the RegisteredProfile instance (or instances) representing the registered profile (or profiles), to which conformance is advertised

The central class adaptation of a profile acts as an algorithmic focal point for all adaptations defined by that profile. The central class adaptation also represents the boundary for clients between using a generic discovery mechanism and using a priori knowledge about the profile, as follows:

- Navigation between the RegisteredProfile instance representing a registered profile and its central instances is defined in this profile with profile advertisement methodologies; these do not require clients to have a priori knowledge about the particular profile.
- Traversal between the central instances of a registered profile and the instances of adaptations defined by that profile requires clients to have a priori knowledge about the profile; this profile does not define generic mechanisms for that purpose.

Implementations that implement multiple profiles in a WBEM server (or even schema classes not covered by profiles) deserve particular attention by clients when navigating the network of instances of adaptations defined by a profile, since it is possible that instances that are not of adaptations defined by that profile are returned along with instances of adaptations defined by that profile. This often requires clients to have a priori knowledge about the way these multiple profiles have been combined in the implementation.

The scoping class adaptation of a profile is used for discovering the central instances indirectly, in cases where there are many central instances to be expected.

In autonomous profiles, the central class adaptation and the scoping class adaptation are the same adaptation (see DSP1001).

This profile defines two profile advertisement methodologies through which an implementation can advertise profile conformance to a particular profile, and through which clients can navigate between the RegisteredProfile instance representing the registered profile and its central instances:

- The first methodology is termed central class methodology ; it is characterized by a direct ElementConformsToProfile association adaptation between the CentralElement and the RegisteredProfile adaptation. This means, every central instance is directly associated with the RegisteredProfile instance representing the registered profile.

  See subclause "Central class methodology" for more information about the central class methodology.

- The second methodology is termed scoping class methodology ; it uses the ElementConformsToProfile association adaptation only between the ScopingElement adaptation of the registered profile and the RegisteredProfile adaptation of the scoping profile. As a result, the central instances of the registered profile are not directly associated through the ElementConformsToProfile adaptation to instances of the RegisteredProfile adaptation that represent the registered profile.

  The ScopingElement adaptation of the registered profile binds to the CentralElement adaptation of the scoping profile, so this profile advertisement methodology basically delegates the traversal of the ElementConformsToProfile association adaptation to the scoping profile.

  This delegation may happen across multiple levels, until some scoping profile finally implements the central class methodology. It is typical (but not required) that that final scoping profile is an autonomous profile.

  See subclause "Scoping class methodology" for more information about the scoping class methodology.

The central class and scoping class methodologies are mutually exclusive for an implementation of a specific registered profile version; exactly one of them shall be implemented.

The decision on implementing central class or scoping class methodology should be left to the implementation; that is, profiles should not require one or the other profile advertisement methodology to be implemented.

In situations in which implementations have small footprint requirements and want to reduce the number of instances or in which the implementation is monolithic and the versions of implemented profiles is homogeneous, the implementation may use the scoping class methodology to reduce the number of necessary ElementConformsToProfile instances.

In situations in which multiple versions of the same profile are implemented, such as multi-vendor providers being integrated into a single WBEM server, the central class methodology is recommended to provide unambiguous relationships through ElementConformsToProfile instances between central instances and the RegisteredProfile instances representing the registered profiles with their versions.

For autonomous profiles, the scoping class methodology gets reduced to become the same as the central class methodology, because scoping element and central element are the same.

An implementation in which multiple versions of a registered profile are implemented may use different methodologies for each profile version, as long as the scoping class methodology is used for at most one of the profile versions implemented. The reason for this restriction is that with more than one use of the scoping class methodology, it is not possible to find out which subset of the central instances are related to which version of the registered profile. An example of this situation could be a system with two network interface cards, each from a different vendor that has delivered an implementation of the Ethernet Port Profile where the implementations are of different versions of the profile. This example also shows that in multi-vendor environments, it may be difficult to coordinate the choice of profile advertisement methodology. Using the central class methodology puts an implementation on the safe side in multi-vendor environments.

This profile defines no mechanisms for explicitly advertising which methodology has been used when implementing a registered profile, because the methodology can be ascertained by testing whether a central instance of the registered profile is referenced by an ElementConformsToProfile instance. Determining the methodology by testing whether the RegisteredProfile instance representing the registered profile is referenced by an ElementConformsToProfile instance only works when it is also ascertained that there is at least one central instance of the registered profile.

### Central class methodology

The central class profile advertisement methodology (or short: central class methodology) is based on a straightforward approach whereby every CentralElement instance (representing the central instances of a registered profile) is associated through ElementConformsToProfile with a RegisteredProfile instance that represents the registered profile and version to which the profile implementation advertises conformance.

This profile advertisement methodology is straightforward because clients only need to traverse the ElementConformsToProfile association adaptation from or to the profile's CentralElement instance to ascertain the profiles to which the implementation advertises conformance.

Implementing this profile advertisement methodology is covered by the CentralClassMethodology feature.

Figure 2 is an object diagram (showing unnamed instances with their top-level class adaptation names) that provides an example of the central class methodology of advertising profile conformance. In the figure, the dotted line bi-directional arrows represent the ability of a client to traverse the ElementConformsToProfile association adaptation in the following ways:

- from a central instance of the registered profile to the RegisteredProfile instance that represents that profile. Note that a particular CIM instance can act as a central instance for more than one profile
- from a RegisteredProfile instance that represents a registered profile to the central instances of that profile

In both cases, the traversal of the ElementConformsToProfile adaptation typically will be across namespaces; that is not represented in Figure 2 and is described in subclause "Cross-namespace associations".

In Figure 2, the ComputerSystem, Fan, and Sensor adaptations are defined in respective profiles; they are all central elements in these profiles and are therefore based on the CentralElement adaptation defined in this profile. The RegisteredProfile instances represent these three profiles.

Central class methodology example

### Scoping class methodology

The scoping class profile advertisement methodology (or short: scoping class methodology) is an approach characterized by the use of the ElementConformsToProfile association adaptation not between the central instances of a registered profile implementation and a RegisteredProfile instance that represents that registered profile, but instead by having that association adaptation at the next (directly or indirectly) scoping profile that implements the central class methodology for itself.

Implementing this profile advertisement methodology is covered by the ScopingClassMethodology feature.

Figure 3 is an object diagram (showing unnamed instances with their top-level class adaptation names) that provides an example of the scoping class methodology of advertising profile conformance with one level of scoping profiles.

Scoping class methodology example

In Figure 3, a client may traverse from a Fan instance to its scoping instance (the ComputerSystem instance) through the SystemDevice association adaptation, following the scoping path defined in the Example Fan profile. Since the ComputerSystem instance is referenced by ElementConformsToProfile instances, the client knows that the corresponding profile has implemented the central class methodology, and can now traverse ElementConformsToProfile to a RegisteredProfile instance that represents the Example Base Server profile, version 1.0.0, which is the scoping profile of the Example Fan profile. Finally, ReferencedProfile is traversed to a RegisteredProfile instance that represents the Example Fan profile, version 1.0.0, to which the implementation of the Fan instance is advertising conformance.

The client may reverse this traversal and start from the RegisteredProfile instance that represents the Example Fan profile to get to the instance(s) of Fan.

The concept is in both cases that the client navigates up the scoping profile hierarchy to the level where a scoping profile implements the central class methodology (as indicated by the presence of instances of the ElementConformsToProfile association adaptation), then traverses from the element side to the profile side or vice versa, and then navigates down the scoping profile hierarchy the same number of steps.

In both cases, the traversal of the ElementConformsToProfile adaptation typically will be across namespaces; that is not represented in Figure 3 and is described in subclause "Cross-namespace associations".

In Figure 3, the ComputerSystem, Fan, and Sensor adaptations are defined in respective profiles; they are all central elements in these profiles and are therefore based on the CentralElement adaptation defined in this profile. The RegisteredProfile instances represent these three profiles.

## WBEM server requirements on CIM namespaces

This subclause defines the roles of Interop namespace and implementation namespace for CIM namespaces, and related implementation requirements for WBEM servers.

Some of these concepts and requirements have a more general scope than this profile. For example, the concept of an Interop namespace is also used by other profiles (e.g. DSP1054) or by WBEM SLP discovery (see DSP0206). Another such example is the concept of cross-namespace associations.

### Interop namespace

Interop namespace is a role of a CIM namespace for the purpose of providing a common and well-known place for clients to discover modeled entities, such as the profiles to which an implementation advertises conformance.

A WBEM server shall implement exactly one CIM namespace that assumes the role of an Interop namespace; that namespace is also called the Interop namespace.

A WBEM server shall expose its Interop namespace using the namespace name:

interop

DEPRECATED

A WBEM server may expose its Interop namespace using the following alternative namespace name, instead of using the "interop" namespace name:

root/interop

The use of this alternative namespace name is not preferred and has been deprecated in version 1.1 of this profile.

Note that clients need to be prepared to deal with any one of these two namespace names.

DEPRECATED

A WBEM server may expose its Interop namespace using additional implementation-defined namespace names that are not one of the namespace names described previously in this subclause. This accomodates WBEM server implementations that support namespace alias names. The client-visible appearance of such a WBEM server is that it exposes multiple distinct Interop namespaces, each with a distinct set of CIM objects (where these sets are equal, except for different CIM object paths).

DEPRECATED

The use of leading slash (/) characters in Interop namespace names is deprecated.

Older WBEM implementations may have considered the slash separator character in a CIM object path URI to be part of the namespace name and thus exposed the namespace name (e.g. in the Name property of CIM_Namespace) with a leading slash character. Version 1.0 of this profile permitted a leading slash character in the name of the Interop namespace. DSP0004 does not permit namespace names to begin with a slash. Therefore, version 1.1 of this profile has deprecated the use of leading slash characters in the name of the Interop namespace.

Producers of Interop namespace names should not create a leading slash character in the Interop namespace name. Consumers of Interop namespace names shall ignore a leading slash character in Interop namespace names when processing them (e.g. for comparison or identification purposes).

DEPRECATED

### Implementation namespaces

Implementation namespace is a role of a CIM namespace for the purpose of providing a place for CIM objects for which no specific namespace requirements are defined.

A WBEM server shall implement one or more CIM namespaces that assume the role of an implementation namespace; each such namespace is also called an implementation namespace.

The names of implementation namespaces are implementation-defined.

### Relationship between Interop and implementation namespaces

A CIM namespace of a WBEM server may play the roles of an implementation namespace and of an Interop namespace at the same time.

Thus, a simple implementation of a WBEM server can expose a single CIM namespace that plays both roles. Of course, that single CIM namespace needs to satisfy the requirements for its name as defined in subclause "Interop namespace".

A typical implementation of a WBEM server will expose a single Interop namespace and multiple implementation namespaces each of which is a distinct namespace implementation.

A profile implementation may span multiple namespaces, including multiple implementation namespaces.

### Cross-namespace associations

Some association adaptations defined in this profile may cross CIM namespaces (within the same WBEM server).

Associations that cross CIM namespaces shall be instantiated in both namespaces. The rationale for this is to support association traversal from either namespace to the other.

Each of these association instances shall have their creation class exist in the same namespace as the association instance. The versions of these association classes in each of the two namespaces may be different; this is needed in order to allow that the implementation namespaces within a WBEM server can be used for objects from different versions of the CIM schema.

# Implementation

The following profile elements are conditional or conditional exclusive on the implementation of this feature:

- CentralClassMethodology feature.

## Adaptations

### Conventions

This profile defines operation requirements based on DSP0223.

For adaptations of ordinary classes and of associations the requirements for operations are defined in adaptation-specific subclauses of the "Adaptations" clause.

For association traversal operation requirements that are specified only in the elements table of an adaptation (i.e. without operation-specific subclauses), the names of the association adaptations to be traversed are listed in the elements table.

The default initialization requirement level for property requirements is optional.

The default modification requirement level for property requirements is optional.

This profile repeats the effective values of certain Boolean qualifiers as part of property, method parameter, or method return value requirements. The following convention is established: If the name of a qualifier is listed, its effective value is True; if the qualifier name is not listed, its effective value is False. The convention is applied in the following cases:

- In: indicates that the parameter is an input parameter
- Out: indicates that the parameter is an output parameter
- Key: indicates that the property is a key (that is, its value is part of the instance path)
- Required: indicates that the element value shall be non-Null
- Null OK: indicates explicitly that the element value may be Null for mandatory, conditional or conditional exclusive properties. This information is not specified as a qualifier in the schema but as an indicator in the profile

### Adaptation: RegisteredProfile: CIM_RegisteredProfile

#### General

This adaptation models registered profiles.

It is important to understand that representing the conformance of a profile implementation to a profile is not the same as representing the profile implementation itself. For example, multiple implementations of the same profile can exist that use the same instance of this adaptation to represent conformance to that profile. Alternatively, each of such multiple implementations of a profile can have its own instance of this adaptation to represent conformance to the profile, even when these profiles have the same version and these implementations use the same implementation namespace.

The implementation type of this adaptation is instantiated ordinary adaptation.

The requirement level for this adaptation is mandatory.

The following table identifies the element requirements for this adaptation.

# Use cases and state descriptions

## State description: SimpleStateDescription

This state description describes a simple scenario in which three example profiles have been implemented. Each of them advertises conformance through an implementation of this profile (i.e. the Example Profile Registration profile). Each implementation of this profile in turn advertises conformance to this profile itself.

The following table lists these three example profiles and for clarity also this profile, and the profiles they reference:

Profiles in the SimpleStateDescription scenario
Profile | Profile Type | Referenced Profile | Profile Reference Type | Profile Reference Name
--- | --- | --- | --- | ---
Example Base Server | Autonomous | Example Profile Registration | Usage | PRP
Example Fan | Usage | SystemFan
Example Power Supply | Usage | SystemPowerSupply
Example Fan | Component | Example Profile Registration | Usage | PRP
Example Power Supply | Component | Example Profile Registration | Usage | PRP
Example Profile Registration | Autonomous | Example Profile Registration | Usage | SelfPRP

The following table lists the class adaptations defined in the three example profiles and in this profile, to the extent they are relevant for this scenario.

The following table lists the implementations of these profiles in the scenario, along with their profile implementation context and implemented advertisement methodology. The profile implementation context of each implemented profile is defined by the profile reference in the referencing profile, and is stated as a path of named profile references relative to the top-level implementation of the Example Base Server profile.

Profile implementations in the SimpleStateDescription scenario
Implemented Profile | Profile Implementation Context | Implemented Advertisement Methodology

Note (1): This RegisteredProfile implementation is an optimization that merges three separate implementations into one implementation, as defined in DSP1001.

The following object diagram shows an example set of instances in this scenario. The implementation follows the recommendation to separate the implementation namespace from the Interop namespace, and it implements the requirement to advertise conformance to this profile through itself.

Simple object diagram

In this scenario, the `system1` instance representing a managed system, the `fan1` instance representing a fan in that system, and the `ps1` instance representing a power supply in that system are all exposed in the implementation namespace "ABCCorp".

The Interop namespace contains four instances of RegisteredProfile that advertise conformance to the Example Base Server, Example Fan, and Example Power Supply profiles, and to the Example Profile Registration profile (that is, this profile).

Profile conformance for the `ps1` instance is determined through the scoping class methodology because that instance is not referenced by any ElementConformsToProfile instances.

Profile conformance for the `fan1`, `system1` and the four RegisteredProfile instances is determined through the central class methodology because these instances are referenced by the ManagedElement end of an ElementConformsToProfile association instance.

Because some of the ElementConformsToProfile instances cross namespaces, the instances of these associations exist in both namespaces. The associated instances exist in only one of the namespaces. For example, the ElementConformsToProfile instance between `system1` and `prof1` has an instance in each of the two namespaces. In the instance in the implementation namespace, ManagedElement is a reference to the `system1` instance in the same namespace, and ConformantStandard is a cross-namespace reference to the `prof1` instance in the Interop namespace. In the instance in the Interop namespace, ConformantStandard is a reference to the `prof1` instance in the same namespace, and ManagedElement is a cross-namespace reference to the `system1` instance in the implementation namespace. See subclause "Cross-namespace associations" for more information about cross-namespace associations.

The scenario defined in this state description is used by some of the following use cases.

## Use case: RetrieveProfileInformationForComputerSystem

This use case describes for the scenario defined in the SimpleStateDescription state description how a CIM client can retrieve profile information for an instance of the ComputerSystem adaptation. In that scenario, the Example Base Server profile (defining the ComputerSystem adaptation) is an autonomous profile.

This use case has the following preconditions:

- The instance path of a ComputerSystem instance (in the implementation namespace) is known.
- It is known that the Example Base Server profile is an autonomous profile and thus its implementation will support the central class methodology.

The main flow for this use case consists of the following sequence of steps:

- Invoke the Associators( ) for ElementConformsToProfile operation on that ComputerSystem instance. The resulting RegisteredProfile instances represent all profiles to which that ComputerSystem instance conforms.
- Iterate through the retrieved RegisteredProfile instances and inspect their RegisteredOrganization, RegisteredName and RegisteredVersion property values, which identify the profiles to which the ComputerSystem instance conforms.

## Use case: RetrieveProfileVersionForFan

This use case describes for the scenario defined in the SimpleStateDescription state description how a CIM client can retrieve the version of the Example Fan profile to which an instance of the Fan adaptation conforms. In that scenario, the Example Fan profile (defining the Fan adaptation) is a component profile and has been implemented using the central class methodology.

This use case has the following preconditions:

- The instance path of a Fan instance (in the implementation namespace) is known.
- It is known that the Example Fan profile is a component profile and that it has been implemented using the central class methodology.

The main flow for this use case consists of the following sequence of steps:

- Invoke the Associators operation on the given Fan instance, filtering on the ElementConformsToProfile association. This will retrieve all RegisteredProfile instances representing profiles to which that Fan instance conforms. In this scenario, only one RegisteredProfile instance representing the Example Fan profile will be returned.
- The value of its RegisteredVersion property indicates the version of the Example Fan profile to which the given Fan instance conforms.

## Use case: RetrieveProfileVersionForPowerSupply

This use case describes for the scenario defined in the SimpleStateDescription state description how a CIM client can retrieve the version of the Example Power Supply profile to which an instance of the PowerSupply adaptation conforms. In that scenario, the Example Power Supply profile (defining the PowerSupply adaptation) is a component profile and has been implemented using the scoping class methodology.

This use case has the following preconditions:

- The instance path of a PowerSupply instance (in the implementation namespace) is known.
- It is known that the Example Power Supply profile is a component profile and that it has been implemented using the scoping class methodology.

The main flow for this use case consists of the following sequence of steps:

- Invoke the Associators operation on that PowerSupply instance, filtering on the SystemDevice association. This will retrieve the (one) ComputerSystem instance that is the scoping instance of the PowerSupply instance.
- Invoke the Associators operation on that ComputerSystem instance, filtering on the ElementConformsToProfile association. This will retrieve all RegisteredProfile instances representing profiles to which that ComputerSystem instance conforms. In this scenario, only one instance representing the Example Base Server profile will be returned.
- Invoke the Associators( ) for ReferencedProfile operation on the returned RegisteredProfile instance representing the Example Base Server profile. This will retrieve all RegisteredProfile instances representing profiles referenced by the Example Base Server profile. In this scenario, three instances will be returned, representing the Example Power Supply, Example Fan, and Example Profile Registration profiles.
- Iterate through these retrieved instances and select the Example Power Supply profile based on the values of its RegisteredOrganization and RegisteredName properties. The value of its RegisteredVersion property indicates the version of the Example Power supply profile to which the PowerSupply instance conforms.

## Use case: AlgorithmForRetrievingProfileInformation

This use case describes for the general case the algorithm for a CIM client to determine to which profiles a central instance of a given profile conforms, when the advertisement methodology implemented for that profile and for its scoping profiles is not known upfront.

This use case has the following preconditions:

- The instance path of a central instance of a given profile is known.
- The profile reference hierarchy between the given profile and its top-level autonomous profile is known, including the scoping path of each of those profiles.

The main flow for this use case consists of the following sequence of steps:

- Invoke the Associators( ) for ElementConformsToProfile operation on the central instance.

- If this operation returns one or more RegisteredProfile instances, the profile has been implemented using the central class methodology, and each (typically one) returned instance represents a profile the central instance advertises conformance to.

  Their RegisteredOrganization, RegisteredName and RegisteredVersion properties of the returned instances identify these profiles.

- If this operation returns no RegisteredProfile instances, the profile has been implemented using the scoping class methodology; in that case, follow these steps:

  - Navigate from the central instance to its scoping instance by following the scoping path defined in the profile.

  - Invoke the Associators( ) for ElementConformsToProfile operation on that scoping instance. This returns the RegisteredProfile instances representing the profiles to which the scoping instance advertises conformance.

  - If this operation returns one or more RegisteredProfile instances, the profiles of the scoping instance have been implemented using the central class methodology, and each (typically one) returned instance represents a profiles to which the scoping instance advertises conformance.

    Go to step 4.

  - If this operation returns no RegisteredProfile instances, the scoping profiles also have been implemented using the scoping class methodology, and step 3 needs to be recursively repeated until a scoping instance is reached that returns such instances. Once that is reached, each (typically one) returned instance represents a profile to which the scoping instance advertises conformance.

    Go to step 4.

- At this point, we know one (or more) RegisteredProfile instances representing profiles to which the top-most scoping instances advertise conformance.

  Select the profile of those top-most profiles that directly or indirectly references the profile you are interested in.

- Invoke the Associators( ) for ReferencedProfile operation on the RegisteredProfile instance representing the selected top-most profile, and repeat that operation recursively on its result, such that you traverse as many profile levels down as you had to traverse profile levels up to the top-most profile in step 3. At each level, if more than one instance is returned, select the profile that directly or indirectly references the profile in question.

  The RegisteredProfile instances resulting from the last such traversal represent the profiles to which the original central instance advertises conformance.

  Their RegisteredOrganization, RegisteredName and RegisteredVersion properties of the returned instances identify these profiles.

## Use case: DetermineConformingInstances

The following figure is an object diagram for this use case and illustrates an implementation of the Example Fan profile described in the SimpleStateDescription scenario. The diagram shows some additional class adaptations defined in the Example Fan profile (compared to that scenario); schema classes are stated in the object diagram only for these additional adaptations. The central instances of the Example Fan profile implementation are the two Fan instances, `fan1` and `fan2`.

The instances of adaptations defined in a profile form a graph, where those instances can be reached by association traversal from the central instances of that profile. Knowing the structure of this graph for the Example Fan profile, a CIM client can navigate to all these instances starting from the central instances of that profile, and can conclude from the existence of these instances that they conform to the Example Fan profile.

This use case determines all instances of ordinary adaptations conforming to the Example Fan profile, given the set of all central instances of that profile. Note that association instances conforming to the Example Fan profile are not determined in this use case; they could be determined using the References() operation.

Redundant fans object diagram

This use case has the following preconditions:

- The instance paths of all central instances of the Example Fan profile are known.

- The navigation graph between instances of all adaptations defined in the Example Fan profile is known.

The main flow for this use case consists of the following sequence of steps:

- For each central instance and for each association adaptation defined in the Example Fan profile that starts at the Fan adaptation, invoke the Associators( ) operation on that instance, filtering on the association class and result class of that association traversal. This will retrieve all conforming instances of ordinary classes one hop away from the central instance; in this case, the RedundancySet instance `fanrset1` and the RegisteredProfile instance `profile2`.

- Repeat step 1 recursively for its resulting instances, until there are no more traversable adaptations defined in the Example Fan profile. This will retrieve the remaining set of conforming instances of ordinary classes; in this case, the ComputerSystem instance `system1`.

## Use case: AlgorithmForDeterminingAdvertisedProfiles

This use case describes for the general case the algorithm for a CIM client to determine the set of profiles advertised by a WBEM server.

This use case has the following preconditions:

- The namespace path of the Interop namespace of the WBEM server is known.

The main flow for this use case consists of the following sequence of steps:

- Invoke the EnumerateInstances( ) operation on the class of the RegisteredProfile adaptation in the Interop namespace.

  This will retrieve the RegisteredProfile instances representing all profiles to which the WBEM server advertises conformance.

- Iterate through these retrieved instances and inspect the values of their RegisteredOrganization, RegisteredName and RegisteredVersion properties, which identify these profiles.

## Use case: AlgorithmForDeterminingTopLevelProfiles

This use case describes for the general case the algorithm for a CIM client to determine the top-level profiles advertised by a WBEM server. Top-level profiles of an implementation are those that are not referenced by any other profiles that are implemented. This is accomplished by determining which instances of RegisteredProfile are not antecedents for any ReferencedProfile associations.

Typically, top-level profiles are autonomous profiles that represent the largest scoping of the CIM representation of the target system and that reference component profiles. Note that it is possible that autonomous profiles are referenced by other profiles.

This use case has the following preconditions:

- The namespace path of the Interop namespace of the WBEM server is known.

The main flow for this use case consists of the following sequence of steps:

- Invoke the EnumerateInstances( ) operation on the class of the RegisteredProfile adaptation in the Interop namespace.

  This will retrieve the RegisteredProfile instances representing all profiles to which the WBEM server advertises conformance.

- Invoke the AssociatorNames( ) operation on the class of the RegisteredProfile adaptation in the Interop namespace, filtering on the class of the ReferencedProfile association adaptation and on source role Antecedent.

  This will retrieve the instance paths of the RegisteredProfile instances representing all profiles to which the WBEM server advertises conformance and that are referenced by other such profiles.

- Reduce the set of all profiles (retrieved in step 1) by the set of referenced profiles (retrieved in step 2), by means of comparing the values of their RegisteredOrganization, RegisteredName and RegisteredVersion properties, which identify these profiles. This results in the set of all top-level profiles to which the WBEM server advertises conformance.

## Use case: AlgorithmForDeterminingCentralInstancesOfProfile

This use case describes for the general case the algorithm for a CIM client to determine the central instances of a given profile that is advertised by a WBEM server, when the advertisement methodology implemented for that profile and for its scoping profiles is not known upfront.

This use case has the following preconditions:

- The namespace path of the Interop namespace of the WBEM server is known.

- The given profile is known by its registered name, organization and version.
- The profile reference hierarchy between the given profile and its top-level autonomous profile is known, including the scoping path of each of those profiles.

The main flow for this use case consists of the following sequence of steps:

- Invoke the EnumerateInstances( ) operation on the class of the RegisteredProfile adaptation in the Interop namespace.

  This will retrieve the RegisteredProfile instances (and their instance paths) representing all profiles to which the WBEM server advertises conformance.

- Out of the returned RegisteredProfile instances, determine the subset of instances where the values of their RegisteredOrganization, RegisteredName, and RegisteredVersion properties match the given profile.

  If that subset contains more than one instance, repeat the following steps for each such instance. Note that there is no requirement that multiple implementations of the same profile in a WBEM server use the same RegisteredProfile instance for advertising conformance.

- Navigate to the RegisteredProfile instance representing the next scoping profile that has implemented the central class methodology, by following these steps, starting from the RegisteredProfile instance:

  - Invoke the Associators( ) for ElementConformsToProfile operation on the RegisteredProfile instance.

  - If one or more instances are returned, the profile has implemented the central class methodology.

    Return from this recursive invocation of step 3.

  - If no instances are returned, the profile has implemented the scoping class methodology.

    Follow these steps:

    - Invoke the Associators( ) for ReferencedProfile operation on the RegisteredProfile instance, filtering on the target role Dependent.

      This will return the RegisteredProfile instances representing the referencing profiles of the profile.

      Select the instance representing the scoping profile of the profile, utilizing knowledge about the profile reference tree.

    - Recursively invoke step 3 for the RegisteredProfile instance representing the scoping profile of the profile.

  - Navigate from the RegisteredProfile instance to its scoping instance by following the scoping path defined in the profile.

  - Invoke the Associators( ) for ElementConformsToProfile operation on that scoping instance. This returns the RegisteredProfile instances representing the profiles to which the scoping instance advertises conformance.

  - If this operation returns one or more RegisteredProfile instances, the profiles of the scoping instance have been implemented using the central class methodology, and each (typically one) returned instance represents a profiles to which the scoping instance advertises conformance.

    Go to step 4.

  - If this operation returns no RegisteredProfile instances, the scoping profiles also have been implemented using the scoping class methodology, and step 3 needs to be recursively repeated until a scoping instance is reached that returns such instances. Once that is reached, each (typically one) returned instance represents a profile to which the scoping instance advertises conformance.

    Go to step 4.

  - At this point, we know one (or more) RegisteredProfile instances representing profiles to which the top-most scoping instances advertise conformance.

    Select the profile of those top-most profiles that directly or indirectly references the profile you are interested in.

## Use case: AlgorithmForDeterminingCentralOrScoping

This use case describes for the general case the algorithm for a CIM client to determine whether a profile represented by a given RegisteredProfile instance has been implemented using the central class methodology or the scoping class methodology.

This algorithm is based on whether ElementConformsToProfile associations are directly linked to the given instance of RegisteredProfile.

This use case has the following preconditions:

- The instance path of a RegisteredProfile instance (in the Interop namespace) is known.

The main flow for this use case consists of the following single step:

- Invoke the Associators( ) for ElementConformsToProfile operation on the given RegisteredProfile instance.

  If one or more instances are returned, the central class methodology has been implemented.

  If no instances are returned, the scoping class methodology has been implemented.

  If the profile represented by the given RegisteredProfile instance is an autonomous profile, the scoping class methodology also has been implemented at the same time, because for autonomous profiles, both advertisement methodologies fall together and result in the same implementation.

## State description: PeerComponentProfileStateDescription

TBD: It is not clear what this scenario intends to say. Simple "peer component" profiles are shown already in the SimpleStateDescription scenario.

TBD: The description argues that this scenario supports the scoping class methodology, but both component profile implementations have used the central class methodology, so it is not clear why this argument is made.

The following figure illustrates the relationship between CIM_RegisteredProfile instances for the peer component profiles Example Fan and Example Sensor. The implementation and Interop Namespaces are depicted for illustrative purposes showing a typical implementation. See 7.1 for more information about namespaces.

Peer component profiles object diagram

In this figure, the Central Instances of three profiles are shown associated through CIM_ElementConformsToProfile to the instances of CIM_RegisteredProfile that represent the profiles with which they are compliant. Also represented is the CIM_RegisteredProfile hierarchy through the CIM_ReferencedProfile associations in the Interop Namespace. In this situation, the Base Server Profile (DSP1004) is the autonomous profile that references the component profiles, the Sensor Profile (DSP1009) and the Fan Profile (DSP1013). This hierarchy would support the Scoping Class methodology for profile compliance advertisement. The relationship between peer component profiles, Fan and Sensor (that is, the Fan Profile includes the Sensor Profile and defines a tachometer sensor), is represented by an instance of the CIM_ReferencedProfile association.

## State description: ProfileComplianceHierarchyStateDescription

The following figure depicts the hierarchy of RegisteredProfile instances associated through ReferencedProfile instances that would represent a modular system with a chassis manager and an included blade server with RAID storage. This figure is provided as an example to illustrate the nature of the relationships among the various autonomous and component profiles. Also depicted are the relationships between component profiles.

Change log
Version | Date | Description
--- | --- | ---
1.0.0 (prelim) | 2006-12-06 | Released as a Preliminary Standard
1.0.0 | 2007-06-25 | Released as a Final Standard
1.1.0a | 2011-12-19 | Released as Work in Progress, with the following changes: Converted to DMTF machine readable format. This included using new concepts from DSP1001 v1.1, such as class adaptations, features, constraints, generic operations and DMTF collaboration structure diagrams. The functionality of this profile in v1.1.0 is the same as in v1.0.0, it is just now described using these new concepts. Implementations that conformed to v1.0.0 of this profile, will also conform to v1.1.0 of this profile. Deprecated the use of leading slash (/) characters in namespace names. For producers of namespace names, tightened the permission to use a leading slash to become a recommendation against using a leading slash. Deprecated the use of "root/interop" as a name for the Interop namespace. Removed requirements on profile authoring, since these are now covered by DSP1001 v1.1. This caused the following v1.0 subclauses to be removed: "Central Class and Central Instance Identification" "Scoping Class and Scoping Instance Identification" "Association Traversal Path Existence" "Overlapping Profile Definitions" Cleaned up terms and definitions. Deprecated the term "subject profile", replacing it with "registered profile". Changes in use cases and state descriptions to better communicate the important scenarios. Other small clarifications.
