Hi all, I am currently working in a technical committee on OASIS defining a document management interoperability specification called CMIS . CMIS shoots for a protocol level interoperability between applications and various repository vendors.
The specification is in a very early stage and a lot of things need to be addressed , but it has peeked the interest of a number of people at Apache already. Since functionally the CMIS specification is a subset of the JCR specification it allows a very simple and straight-forward mapping to a fully compliant JCR repository such as Jackrabbit. Similar to the existing protocol layers (webdav etc) on top of JCR that are already part of Jackrabbit, I would like to propose that we initiate first tests with an implementation in a sandbox project. I think that there are going to be a lot of benefits from such an implementation. First it will allow any JCR implementation to be CMIS compliant automatically (once the specification is released ;) ) and allow us to find the issues to be fixed in the specification itself and drive it into a good direction. But most importantly it will provide an platform for interested parties to collaborate in the open on an implementation. Most of the organizations on the technical committee of CMIS are already heavily involved at Apache either as contributors or as sponsors and are also on the JCR expert group. Let me know what you think. regards, david  http://lists.oasis-open.org/archives/tc-announce/200810/msg00003.html  http://roy.gbiv.com/untangled/2008/no-rest-in-cmis
