Intro

Semantic mediation is a required mechanism to allow system interoperability and data integration. Such mechanism comprises a set of key operations including controlled vocabulary definition and maintenance, terminology mappings, and inference, among others. MMI has advanced a proof-of-concept prototype system, the MMI Ontology Registry and Repository, which provides the basis for semantic mediation. A complementary service is provided by the MMI Ontology and Term URI Resolver. This service provides URI resolution for both whole vocabularies and individual entities defined within. Content negotiation allows diverse clients to access the corresponding contents in the appropriate form as described in Resolving Term and Ontology URLs.

Goals

This group will determine the required vocabularies/ontologies that will support the association of references to corresponding definitions in SWE documents. It will also discuss and determine UI functionalities that exploit the semantic information associated with data registry and observation services. 

Use cases

We need to determine the relevant use case(s). Some possibilities are:

1. Data provider annotates SWE documents with references to semantic definitions.
2. User (or software agent) searches for data providers and observation data via semantic queries.
3. User (or software agent) gets data and then navigates (linked) metadata elements in associated vocabularies and ontologies.
