Yeah, that's the main issue and we should really do something about it. I have been tinkering with various design over the last couple of days. None of them made me completely happy yet. What I quite like about the current design is that you can "upgrade" a collection into a paged collection without changing the link to the collection: /x --[property]--> /collection /collection a Collection member .... and then, at some point when /collection grows too big, you just add a nextPage link: /collection a Collection member .... nextPage /collection?page=2 (but as we already discussed, it may be unclear what is meant in that case, i.e., just the first page or all pages) Your proposal was to model this as Collections (with and without members) and Pages (always with members). That means that you always have to handle two cases. Perhaps it would be simpler to turn *all* Collections into, what's currently called, PagedCollections. Some of these PagedCollections then just happen to consist of just a single "page". One design that I've tried was to rename PagedCollection to PartialCollection and move all the paging information to a separate entity. Something like /collection a PartialCollection member ... paging [ totalItems ... itemsPerPage ... nextPage ... ... ] But that still doesn't resolve the issue that we can't point to the complete collection and individual PartialCollections separately. One thing we could of course do is to just acknowledge that in the spec and say that pointing to a PartialCollection (from something else than the pagination links) is equivalent to transforming all interlinked PartialCollections to a single Collection referencing all members and pointing to it. Perhaps you, or someone else, has some other, better ideas. -- Markus Lanthaler @markuslanthaler
