Creating an Ordered Collection (proposal)
Ordered header for use with MKCOL
Value is URI of ordering semantics
Example
MKCOL /collection1/ HTTP/1.1
Host: www.foo.com
Ordered: http://www.foo.com/semantics/s1.txt
Notes:
Since orderings are properties of collections, it makes more sense to create them when the collection is created than incidentally when the first member is added or by PROPPATCH after creation of the collection.
You can change your mind about the ordering semantics later by PROPPATCH.
You can change your mind later about whether the collection is ordered by PROPPATCH.
Would an ordering still get created automatically if someone did PUT or ADDREF with Position on an unordered collection?
Can you still directly create the DAV:ordering property with PROPPATCH?
