Semantic Indexing

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:

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.
