Following up on Gianugo's wild idea [1] that Cocoon could be used to implement the DASL part of a WebDAV server..
Cocoon would proxy the following operations to the WebDAV backend: GET, HEAD, POST, PUT, DELETE, MKCOL
Not really. You need to keep your metadata repository in sync, so you need to intercept PUT, DELETE & MKCOL, acting accordingly on the JDBC store, so you would need a bit more than just proxying.
And handle the following operations: PROPFIND, PROPPATCH, SEARCH
Problem areas:
-OPTIONS, backend response must be completed with DASL info (easy)
-MOVE and COPY, URIs must stay in sync between file storage and properties, not too hard to do
Same with methods above...
-Locking must lock both file contents and properties (I assume), slightly harder
Not really. You need to keep trace of lock tokens, but it shouldn't be that hard.
Does this sound too hackish? ;-)
Not at all, infact it was something I wanted to investigate sooner or later (with DAV ACL being the next one to tackle). Care to jump in? :-)
