I think that there are a number of possible answers to your question, Laufer. The one that I immediately think of is the Linked data API [1] which provides a framework for the kind of thing you refer to here. It maps URIs to SPARQL queries that can return lists of 'everything below here in the graph.' There are a few implementations of the Linked Data API, one that gets most attention these days is ELDA [2]. An alternative URI -> SPARQL mapping tool is Pubby [3] which is used by DBPedia (it's from the same team). To take a fictitious example, I agree it would be nice if: http://data.example.com/id/building/A/rooms returned a list of all the rooms in building A http://data.example.com/id/building/A/rooms/ground returned a list of all the rooms on the ground floor of building A http://data.example.com/id/building/A/rooms/ground/01 identified room 01 on the ground floor of building A. That's a nice thing to set up, and using something like the tools listed above is certainly possible. It conflates URI design with implementation (which may or may not be a good thing). Whether that's an actual Best Practice... is for the WG to decide :-) Phil.
