We're using collections to associate requirements artifacts with a given team or test corner, but it would be handy to have a collection that is a collection on collections, sort of like this:

Big Collection --+--> Regular collection 1 ---> Requirement 1

                 |                              Requirement 2

                 |                               

                 '--> Regular collection 2 ---> Requirement 3 

                                                Requirement 4

Is that possible? When I go into Big Collection and try and have it point at a Regular Collection, the options seem to be greyed out.

Hi Paul
There is an item that would fit a similar use case here https://jazz.net/jazz03/resource/itemName/com.ibm.team.workitem.WorkItem/44252
3.0.1 does not currently allow collections of collections.

...how in RRC do we best associate or come up with a view where we can see all the requirements associated with a given department or team, while at the same time being able to composite all of the requirements up for a multi-team area?

There are five primary grouping mechanisms in RRC V3.0.1:

1. Collections, which include individual artifacts. A collection has a unique name and URL

2. Folders (similar to folders / directories on your local hard drive)

3. Tags

4. Attributes

5. Review and approval artifacts. Can include any set of artifacts (but not other review artifacts). Can optionally include specific revisions of artifacts (formal review). Also has a unique name and URL.

You can create saved filters that include various combinations of (2) - (4) above (including which attributes to show in the columns).

Optionally, from any set of artifacts in a view, you can create a collection. Artifacts can be in more than one collection.

I believe it's also possible to embed a collection into a textual artifact, and include that artifact in another collection. It's unlikely to meet your needs (it's a bit unwieldy), but I mention it here for the sake of completeness.
