As a developer, what problems does the KB_bundle product solve for you?

• Quick start for using Semantic Web technologies - reduces your learning curve.
• KB_bundle is free for non-commercial use (including creating demos for your boss) and has a low commercial use license cost: $200 for a combination 1-develper/1-deployment-server license
• Low cost solution for designing and implementing custom document repositories with full search and indexing support, and document clustering functionality.
• Generate short summaries of any text documents.
• Utilities for wrking with many rich document formats.

Version 1 of the KB bundle product (Java version) will be available August 2008 under either a free non-commercial use (compiled only) license or a commercial use license (compiled and source code versions).
JavaDoc documentation for KB_bundle (updated 6/28/2008).

I use the Sesame RDF/RDFS/OWL libraries on the Java platform and the Franz AllegroGraph commercial product for development on the Common Lisp platform.

I also offer Semantic Web and Knowledge Management consulting services.
