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.
