I’m starting to work on my tasklist for Matterhorn (Opencast v1.0). One of the research tasks I have is answering how a number components spread across different JVMs (or not running in a JVM at all) and different servers can efficiently access a common content repository. There may not be an efficient mechanism for non JVM components, but there must be some kind of network access.
I’ve put together some experiments to help me understand JCR in general and Jackrabbit in particular, with the hope that we’ll be able to leverage this JCR implementation in Matterhorn. So far, I’ve had luck reading and writing to JCR from multiple JVMs. The writes from JVM1 show up in JVM2, so this looks like a good start. The code is at https://opencastproject.svn.sourceforge.net/svnroot/opencastproject/jcr/
