Announcing TopBraid Composer 2.0

We are very excited to announce the release of TopBraid Composer 2.0 today. This milestone release makes Composer the first professional Semantic Web development tool to support the evolving OWL 1.1 specification. We have also significantly improved the inferencing architecture, allowing TopBraid users to execute reasoners in a delegation chain, and to use SPARQL as a rule language. I will write detailed blog entries about these features shortly.

In addition to these and many other new features (listed on our web page), we have spent extra time debugging to make sure that Composer stays ahead of its competitors in terms of stability and performance. We have discovered and worked around some Eclipse incompatibilities on Mac computers. Doing a major release was also a good opportunity to review and update the help pages: I actually ended up adapting all pages and replacing all the screenshots. Finally, we have simplified the installation on Windows, and now provide a clean installer package including Java and Eclipse.

Reflecting on the rapid evolution of the tool since its first release early 2006, I would like to acknowledge all of our users who have provided invaluable feedback and otherwise supported our work. We very much appreciate to have you on board! Many of the features that you find in Composer these days are also a direct result of TopQuadrant's semantic web projects with customers around the world. We all hope you enjoy TopBraid Composer 2.0 as much as we do!
