Hi, Apologise for cross-postings. Are there somebody trying to index/search using "semantics" (as a protocol)? The vision I'm trying to figure out is to use semantics as a protocol facade for browsing an index and a repository "smartly". It's nothing but relegating the features of a linked graph only as a "resource map" of where the data is currently held and linked and which should "understand semantic/intelligent links" The idea is drafted here: http://cognescent.googlecode.com/files/Index.pdf I hope there is some (open) work done in this way. Would be nice to know if there is a working example or if the idea is worth the effort implementing it. Best, Sebastián.
