Hi, very happy to join the Jena community. To start with, I have a few basic questions: 1) Is Jena still active in development, and with a good user community? 2) Anyone know of any commercial use of it? 3) For millions of entities and relationships, will there an efficiency problem? 4) Can Jena handle OWL ontology which are created by Protege?
Thank you in advance for comments or advice. Martin
