Summary
Description of the profile
A key function desired by virtually all stakeholders is the ability to query by example using an item from a model or vocabulary (e.g., data element, property, data type, constraint, relation, concept, etc.) to find equivalent and related elements defined anywhere in the knowledge repository. The response should provide an easily understood description of the degree and nature of the semantic convergence between the example item and responsive items.
An artifact is a managed resource within the Semantic Infrastructure.
An artifact is associated with the following capabilities:
- descriptions to enable the artifact to be visible, where the description includes a unique identifier for the artifact and a sufficient, and preferably a machine processible, representation of the meaning of terms used to describe the artifact, its functions, and its effects;
- one or more discovery mechanisms that enable searching for artifacts that best meet the search criteria specified by the service participant; where the discovery mechanism will have access to the individual artifact descriptions, possibly through some repository mechanism;
- accessible storage of artifacts and artifact descriptions, so service participants can access, examine, and use the artifacts as defined.
Discovery is the set of capabilities which enable searching for artifacts that best meet the search criteria specified by the service participant.
Aspects of discovery include:
- Search for services, policies, and other artifact descriptions accessible via some repository mechanism
- Search for operational characteristics of artifacts, which are metrics defined in artifact descriptions. The information is accessible via infrastructure monitoring capabilties or directly from services.
- Tracking and notification mechanisms related to artifact usage, service availability, operational conformance
Capabilities associated with discovery are delineated in the functional profiles inherited, and specialized, by the discovery profile, namely:
- Artifact
- Metrics
- Interoperability
Descriptions provide up-to-date information on what a resource is, the conditions for interacting with the resource, and the results of such interactions. As such, the description is the source of vital information in establishing willingness to interact with a resource, reachability to make interaction possible, and compliance with relevant conditions of use.
Architectural implications of interoperability on the Semantic Infrastructure are reflected in the following capabilities:
- one or more discovery mechanisms that enable searching for described resources that best meet the criteria specified by a service participant, where the discovery mechanism will have access to individual descriptions, possibly through some repository mechanism;
- tools to appropriately track users of the descriptions and notify them when a new version of the description is available.
Artifact Descriptions include references to metrics which describe the operational characteristics of the subjects being described
Architectural implications of metrics on the Semantic Infrastructure are reflected in the following capabilities:
- access to platform infrastructure monitoring and reporting capabilities
- access to metrics information generated or accessible by related services
- mechanisms to catalog and enable discovery of which metrics are available for a described artifact and information on how these metrics can be accessed;
- mechanisms to catalog and enable discovery of compliance records associated with policies, contracts, and constraints that are based on these metrics.

provenance
Description
While the Resource identity provides the means to know which subject and subject description are being considered, Provenance as related to the Description class provides information that reflects on the quality or usability of the subject. Provenance specifically identifies the entity (human, defined role, organization, ...) that assumes responsibility for the resource being described and tracks historic information that establishes a context for understanding what the resource provides and how it has changed over time. Responsibilities may be directly assumed by the Stakeholder who owns a Resource or the Owner may designate Responsible Parties for the various aspects of maintaining the resource and provisioning it for use by others. There may be more than one entity identified under Responsible Parties; for example, one entity may be responsible for code maintenance while another is responsible for provisioning of the executable code. The historical aspects may also have multiple entries, such as when and how data was collected and when and how it was subsequently processed, and as with other elements of description, may provide links to other assets maintained by the Resource owner.
