atom doesn't address such a thing. it would be a cosmo feature. we
could make it so that POST to a collection with a certain media type
would be interpreted as diffs for multiple resources and that the POST
is transactional. the data contained in the request body would have to
identify each resource to update and whatever information is needed to
make each update happen. this could look like a mime multipart
message, or it could look like a bunch of rdf triples, or whatever we
decide we want. really there's nothing atom-specific about this. it's
just basic http.
