Adrian Otto commented on CAMP-42:
---------------------------------

Alex,

I suggest:

1) I will open a ticket to improve the spec to prefer association over composition in important resources like platform. That would be a great improvement, but is another issue.

2) You draft a resolution to this issue that addresses the need for paginated collections.

3) Leave the subject of filtering out of scope for now, and revisit it if we become aware of anyone offering those features through our extensibility mechanisms, and get a sense of what approach(es) is/are chosen and why.

> Currently the spec only dictates requests whose response is an entire Resource object.  These Resources could be very large however, and it is wasteful for everyone to send the entire object if, as will commonly be the case I expect, the client is only interested in a small piece of the Resource.
> This spec should define how a client can restrict a query to selected items of the Resource.  This should include:
> * filtering: selecting a specific key or restricting to a set of keys
> * pagination: selecting a specific element or range of elements (where a key's value is of type list)
