What People want from Internet Resource Description
URCs are many things to many people. Roughly, their perceived uses can be
categorized as follows:
- carrying specific metainformation to distinguish between resource
instances (for URN resolution -- the original reason for which URCs were
conceived)
- list of published or mirrored instances
- location of instance
- format of instance
- cost of instance
- more service-specific information
- information to support cacheing systems
- history of document usage
- general cataloguing information
- application- or service-specific metainformation
- e.g., melodic contour representation for a specific
music-retrieval system
- semantic weightings for a particular text-retrieval system
- labels for a ratings service
