Description of the profile Dynamic retrieval and enforcement of the policies that are in effect for a service interaction in the areas of data transformation. This information can be used either during the design of the orchestration or during the execution of the defined flow. Data Transformation Policy includes the following capabilities * definition and configuration of Data Transformatio policy * author policy * store policies * approve policies * validate policies * execute policies at runtime 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. Artifact descriptions change over time and their contents will reflect changing needs and context. Architectural implications of change on the Semantic Infrastructure are reflected in the following capabilities: * mechanisms to support the storage, referencing, and access to normative definitions of one or more versioning schemes that may be applied to identify different aggregations of descriptive information, where the different schemes may be versions of a versioning scheme itself; * configuration management mechanisms to capture the contents of the each aggregation and apply a unique identifier in a manner consistent with an identified versioning scheme; * one or more mechanisms to support the storage, referencing, and access to conversion relationships between versioning schemes, and the mechanisms to carry out such conversions. Artifact Descriptions may capture very focused information subsets or can be an aggregate of numerous component descriptions. Service description is an example of a likely aggregate for which manual maintenance of all aspects would not be feasible. Architectural implications of composition on the Semantic Infrastructure are reflected in the following capabilities: * tools to facilitate identifying description elements that are to be aggregated to assemble the composite description; * tools to facilitate identifying the sources of information to associate with the description elements; * tools to collect the identified description elements and their associated sources into a standard, referenceable format that can support general access and understanding; * tools to automatically update the composite description as the component sources change, and to consistently apply versioning schemes to identify the new description contents and the type and significance of change that occurred. Descriptions of interactions are important for enabling auditability and repeatability, thereby establishing a context for results and support for understanding observed change in performance or results. Infrastructure services provide mechanisms to support service interaction. Architectural implications of interactions on the Semantic Infrastructure are reflected in the following capabilities: * one or more mechanisms to capture, describe, store, discover, and retrieve interaction logs, execution contexts, and the combined interaction descriptions; * one or more mechanisms for attaching to any results the means to identify and retrieve the interaction description under which the results were generated. * mediation services such as message and event brokers, providers, and/or buses that provide message translation/transformation, gateway capability, message persistence, reliable message delivery, and/or intelligent routing semantics; * binding services that support translation and transformation of multiple application-level protocols to standard network transport protocols; * auditing and logging services that provide a data store and mechanism to record information related to service interaction activity such as message traffic patterns, security violations, and service contract and policy violations * security services that abstract techniques such as public key cryptography, secure networks, virus protection, etc., which provide protection against common security threats in a SOA ecosystem; * monitoring services such as hardware and software mechanisms that both monitor the performance of systems that host services and network traffic during service interaction, and are capable of generating regular monitoring reports. 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. Artifact Descriptions include references to policies defining conditions of use and optionally contracts representing agreement on policies and other conditions. Architectural implications of policy on the Semantic Infrastructure are reflected in the following capabilities: * descriptions to enable the policy modules to be visible, where the description includes a unique identifier for the policy and a sufficient, and preferably a machine processible, representation of the meaning of terms used to describe the policy, its functions, and its effects; * one or more discovery mechanisms that enable searching for policies that best meet the search criteria specified by the service participant; where the discovery mechanism will have access to the individual policy descriptions, possibly through some repository mechanism; * accessible storage of policies and policy descriptions, so service participants can access, examine, and use the policies as defined. Policy capabilities are specialization of Artifact capabilities. While policy and contract descriptions have much of the same architectural implications as Service Descriptions, mechanisms supporting policies and contracts also have the following architectural implications: * decision procedures which must be able to measure and render decisions on constraints; * enforcement of decisions; * measurement and notification of obligation constraints; * auditability of decisions, enforcement, and obligation measurements; * administration of policy and contract language artifacts; * storage of policies and contracts; * distribution of policies/contracts; * conflict resolution or elevation of conflicts in policy rules; * delegation of policy authority to agents acting on behalf of a client; * decision procedures capable of incorporating roles and/or attributes for rendered decisions. While policy and contract descriptions have much of the same architectural implications as Service Descriptions, languages supporting policies and contracts also have the following architectural implications: * expression of assertion and commitment policy constraints; * expression of positive and negative policy constraints; * expression of permission and obligation policy constraints; * nesting of policy constraints allowing for abstractions and refinements of a policy constraint; * definition of alternative policy constraints to allow for the selection of compatible policy constraints for a consumer and provider; * composition of policies to combine one or more policies. h6.

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.

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. h6.
