Fogbeam's FOAF library in Java
Written by Fogbeam Labs for use in Quoddy, Neddick and other projects, the goal is to eventually provide a 100% spec compliant FOAF library, in Java, licensed under the Apache License v2 (ALv2). Right now this isn't even close to 100% done, and it will be evolving along with our support for FOAF in Quoddy and Neddick.
