[Rdfapi-php-interest] FILTER implemented?

[GSO <gs...@ya...>]

A quick question if I may, are FILTER queries currently supported?  An example:

PREFIX ll: <http://www.gsowww.uklinux.net/librarylinks/vocabulary#>
SELECT *
WHERE { ?url ll:title ?title .
	?url ll:abstract ?abstract .
	?url ll:date ?date .  FILTER  (?date >= 12345 && ?date <= 54321) .
	?url ll:publisher ?publisher }
ORDER BY DESC(?date)
