Re: Draft Protocol question -- Creating a child basic container for annotations

Hi Tim,

That's correct. You would have the interaction model specified in the POST,
via the Link header.  The actual specification documentation is 5.2.3.4 in
LDP.

As to the protocol doc, I don't know if we need to re-specify that, rather
than the annotation specific interactions.  Or, in other words, I think the
scope of the document is limited to managing annotations in containers, and
we can assume that the containers already exist.  Open to arguments to the
contrary, if we think that management of the containers is something we
need to specify as well.
