Flexible, use case specific metadata cataloging for CAS

Hi All, I picked up OODT today and immediately thought about an implementation of Apache Gora [0] for abstracting persistence within the CAS metadata catalogue. Right now, for me, the persistence of my metadata catalogue to Lucene or MySQL is sufficient and I have no immediate justification for usi
