Title
- Discover content using semantic queries
Description
Currently ebXML Registry allows content to be discovered using ad hoc queries which are based on predicates defined over attributes of RIM classes.This use case envisions allowing content to be discovered using semantic ad hoc queries which are based on predicates defined over attributes of Ontology class instances in addition to attributes of RIM classes .
The result is that a Registry Client may now discover content by expressing their intended target using enhanced expressive power, semantic clarity and reduced ambiguity.
