There are a few Jackrabbit mailing list threads discussing such issues, mostly from the point of view of a user who wants to access an existing relational database through the JCR API. Jackrabbit quite explicitly does not support such use cases, so mostly those threads have ended fast. In general it would be possible, and actually quite interesting, to implement a JCR-to-JDBC bridge that would for example expose each relation as a node type and a related (flat) set of nodes. One could also do the reverse, a JDBC-to-JCR bridge that exposes each JCR node type as a separate relation (with just the non-residual properties mapped). However, both such bridges are at best non-trivial to implement (especially if you want even simple write functionality), and so far I haven't seen very much demand for them. BR, Jukka Zitting
