Semantic web for LAMP systems

Just aquainted myself a tiny bit with ARC, RDF Classes for PHP. Might be useful in the Bioclipse / Semantic MediaWiki integration that is in the thoughts for the coming months. ARC "framework", or RDF API used by RDF modules in Drupal, and has been talked about being the substitute for the currently used RAP framework in Semantic MediaWiki (used if one wants to set up a SPARQL endpoint for a Semantic MediaWiki).

On a different note, there are a bunch of nice web apps built on ARC over at, most notably trice, a semantic web application framework.
