Goals
Enable resource discovery.
- E.g., GlOSS needs to know available resources and their content summaries.
Enrich query formulation support.
- E.g., Query Constructor needs to show users the names of attributes and their documentation.
Drive query translation.
- E.g., Query Translator needs to know the capability of the target services.
Facilitate result analysis.
- E.g., SenseMaker needs to transform documents (sets of attributes) into a canonical model (i.e., mapping of attributes and their values).
