Summary

Description of the profile
...
The Semantic Infrastructure provides the behavioral semantics required for dynamic composibility of services or generation of distributed queries. This includes runtime contract discovery.
An artifact is a managed resource within the Semantic Infrastructure.
...
- 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.

Service orchestration and choreography allows both application developers and non-developers to discover service "building blocks" that can be composed dynamically to provide business capabilities. Special cases include the orchestration of multiple services for a distributed query, or for a transactional workflow. Service orchestration and choreography will leverage static and behavioral semantics from the Semantic Infrastructure 2.0. The Semantic Infrastructure provides the behavioral semantics required for dynamic composibility of services or generation of distributed queries. This includes runtime contract discovery and negotiation to determine composibility of services based on service capabilities and constraints. Another use case is dynamic retrieval and enforcement of the policies that are in effect for a service interaction in the areas of logging, validations, data transformation, or routing. This information can be used either during the design of the orchestration or during the execution of the defined flow. Link to use case satisfied from caGRID 2.0 Roadmap: Federated query over the TCGA data and other data sets is performed using a service orchestration. | Semantic Infrastructure Requirements::caGRID 2.0 Platform and Terminology Integration::

The Semantic Infrastructure provides the behavioral semantics required for dynamic composibility of services or generation of distributed queries. This includes runtime contract discovery.
...
- access to contract modules
- unique identification for each contract
- access to the metamodel defining terms used to describe the contract, its functions, and its effects;
- one or more discovery mechanisms that enable searching for contracts that best meet the search criteria specified by the service participant; where the discovery mechanism will have access to the individual contract 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.

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.
