well, I think it's convenient to have date times represented as xsd:dateTime in RDF... now yes, ideally they could be mapped to long timestamps in TDB. This wouldn't really change the core issue though, which is that all the triples are fetched, and only then their object is compared, instead of doing the comparison at the time of fetch. I can't really test converting my values to longs though so I can't really say... Best, -- Elie
