[redland-dev] Redland PostgreSQL functions

[Michael Nachbaur]

Hello all,

I have recently been playing with the libxml2 support for PostgreSQL - 
integrating libxml2 with the database to perform XPath and XSLT 
functions against XML content stored in a database - and have had the 
idea that perhaps the same could be extended to Redland.

I know there is currently now PostgreSQL database storage support for 
Redland, though assuming this were the case, I was thinking it would be 
quite an interesting feat to be able to perform SPARQL or other sorts 
of queries - or even simply apply primitive RDF queries - against the 
database contents from within the database itself.

This would permit RDF queries to be performed from within SQL 
statements, from inside stored procedures and triggers, and potentially 
be able to represent the result of SPARQL queries as virtual tables.

My C skills are lacking however, so I wanted to know what other 
developers here thought of this idea, how feasible it might be, and if 
anyone else thinks that node-graph queries of an RDF model would be an 
interesting capability to add to an RDBMS?
