LSID
ODO - Ontologies, Databases, and Optimizations
I have been working at IBM for the past couple years on a project called the IBM Semantic Layered Research Platform . The project is a collection of software components that provide support for semantics through the entire application-middleware stack.
We released the source code for the entire project in November under the Eclipse Public License .
My part of the project originates from my work on the LSID project. I had been working with a lot of RDF metadata while maintaining the Perl LSID development stack and realized that (back in early 2004) that a clean, useful and relatively bug free RDF framework didn’t exist. It turns out that a number of people shared my concerns and were independently creating their own ad hoc Perl libaries for RDF processing.
