- Could we have some HTTP-rendering examples of how to add/remove Kind instances to/from a collection other than the defining collection?
AE: I'll get some examples added asap.
Good, I just want to make sure the add/remove collection tag thing does not end up with the same problems as we had with Links in the past.
AE: Ooops my mistake - Actions should not have been mentioned (I'll make that edit). Paging through collections should be accomplished using Links (e.g. in HTTP header renderings) as you point out. A beginning example can be found here [1] in section 1.4.3.1. We need to make sure that the current incarnation of Links can accommodate this behavior.
Implementing navigation using Link Headers should be easy, we can grab that part directly from the RFC and it will not conflict with the OCCI specific use of Link Headers. Regarding confusing terminology could we be _very_ consistent on using "Link Header" when we refer to RFC5988 and just "Link" when referring to the OCCI base type? I think we should at least consider renaming the OCCI Link base type to something else because the current situation will confuse people.
AE: we could use something like "http://schemas.ogf.org/occi/core/collections#" as the scheme for tags?
We could but Alex point of keeping the namespace clean is also important. Not sure which is best. Will there be only one Category for the collection stuff or will there be more (defined by Core) in the future? Speaking of user defined collections. How is the mix-in attribute occi.core.tag supposed to work when a user adds a Resource instance to 2 or more collections? regards, Ralf
I will annotate the wiki page as well.
regards, Ralf

Hey all, I've placed a write up of how categories and collections related to each other. Also there is how one can interact with collections. I've tried to keep the description as non-rendering-specific as possible.

If there are comments etc please annotate the wiki page at the appropriate place or place your questions in the "Open Issues" section.
