Complex search offers a natural and user-friendly way to find services by progressively refining search results using a variety of criteria including attributes, artifacts, classification, usage scenarios, and dependencies. This includes runtime contract discovery, a powerful query 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.

Info
titleNote on Search Categorization

For the purpose of requirements categorization, the search functional profiles were interpreted as follows:

  • Discover: search by example, implemented as an interface that takes an existing item and discovers similar items within the knowledge repository
  • Find: search by query, implemented as an interface which accepts criteria and finds responsive items in an index of some nature
  • Visualize: search by navigation, implemented as a graphical interface to follow linked data relationships through models and terminologies

Service generation is the ability to generate services from user defined service metadata. The semantic infrastructure provides this metadata and the platform leverages this metadata for service generation. The constraints and policies specified in the semantic infrastructure are inherited by the platform and are enforced as runtime policies.
