While this is all lovely... Why is it that Google docs API and CMIS both use THE SAME solution to returning an ATOM entry which has a link rel to a feed which outlined the resources which are part of this object? Do we need to leave the Atom/Atom Feed spec to solve this problem? I don't like the idea of SIMPLE suddenly needing knowledge of 2 specifications (ATOM and ORE) Dave T On 19 Jan 2011, at 18:57, Richard Jones wrote: > Hi Rob, > > I've just mocked up another deposit receipt serialisation which I think is a > valid Resource Map.
