Some other interesting sources

Hello everyone,

Similar to openlink and franz is also ontotext(http://www.ontotext.com/), where they have created a variety of useful products based on semantic web technologies.
Since we are trying to reach a variety of graph based approaches we could also try and reach http://jena.apache.org/ from the apache foundation.

There are also many other institutions (mainly academic), that currently work on graph technologies or some hybrid approaches with the semantic web stack.

Regards,
Michael.
