Re: Bridging DataStore and Web

The same binary object could be stored in multiple places (nodes) and thus
have multiple file names and extensions. I believe file name and extension
are attributes (that may change) and should not be bound to the content.

In some cases (DbDataStore) there is no path, and in some implementations it
may not be stable.

These would actually perform true caching functionality and could implement

JCR-1892 should allow you to implement something like the HTTP ETag feature
- http://en.wikipedia.org/wiki/HTTP_ETag - if this is what you need.
