The underlying knowledge representation technology was developed in the late 1990's and predates rdf and owl. There are also distinct differences.

It should be fairly easy however to put a SPARQL layer on top of our API. In fact, I believe this could be done by someone outside of True Knowledge.

I think about this perspective too, but this will require a lots of work and a lots of data stored to recode your [uri] to w3c uri".

It may become easier to just dump yuor data to other storage engine then translate data on evry query and decomposite complex SPARQL a number of TKQ, specialy then one SPARQL will require non constant number of TKQ.

I think you have to think about standarts, even if you begined earlyer.
