What's Needed?
In order to deploy distributed cross-searching in an open, application-independent way we need:
- Metadata in a machine-readable format - RDF
- Syntax for describing the metadata - see RDF pages at <URL: http://www.w3.org/RDF/>
- Language for processing metadata - see XML-QL, A Query Language for XML at <URL: http://www.w3.org/Submission/1998/12/>
- An open authentication infrastructure
Issues:
- Timescales • Costs
- Software support • Protocol support
- Short-term pragmatic solution vs long-term purer solution
