...
The Decision support service provides a powerful discovery mechanism that allows either the service orchestrator or a program to find the services that best fit the requirements of a given process.
This increases both runtime and design time flexibility by enabling selection of services based on computable metadata. This includes Included are support for runtime contract discovery and negotiation; this , which supports the key requirement of the semantic infrastructure which is to support semantic workflow composition.
Runtime contract discovery and negotiation capabilities provided by the decision support service Decision Support Service will allow the service orchestration tool to specify expressions that are processed by the decision support service Decision Support Service, to deliver service orchestration /and compatibility recommendations.
The decision support service Decision Support Service also provides a set of interfaces for generating reports based on specific user-defined criteria to better identify, for example, services of with specific profiles, etc. The governance service Governance Service uses the decision support Decision Support Service for generating compliance reporting based on specific input criteria.
The decision support service Decision Support Service allows users to construct user queries including but not limited to:
- User friendly and ad

- hoc queries
...
- using natural language expressions
...
- User friendly semantic web queries
- Visual queries
, visual queries, etc. The results of these queries can be structured in multiple formats; this . This is the primary interface between the caGRID caGrid 2.0 service registry and the SI Semantic Infrastructure 2.0 infrastructure.
The Decision Support Service provides capabilities to:
- Construct and execute semantically rich queries.
- Develop custom analysis reports to support decision making
- Export information in multiple formats, allowing the application of custom algorithms /and rules to the metadata to for additional analysis
- Ability to run reasoners (like Web Ontology Language (OWL) reasoners) and view results in a user friendly format
- Ability to perform impact analysis to identify dependencies and constraints
- Support both design - time and run-time runtime contract discovery and negotiation

Service Description
The Decision Support Service will provide the following functionality:
- Provide a multiple mechanism mechanisms to construct semantic queries
- Support natural language queries
- Specify the format of reports generated as a result of the queries
- Search the registry for items including but not limited to a model, existing value sets, OID's and Object Identifiers (OIDs) in an OID registry, etc.
- Retrieve an existing model from the Knowledge Management Service, and retrieve schemas and form definitions.
- Download /Export and export information in user defined formats, applying the appropriate transforms
- Support for executing reasoners and display of information in a user friendly format
- Provide interfaces for service discovery and runtime contract negotiation.
- Identify dependencies
