With respect to the Multiple Resources model[1] that emerged in Chicago

1. It would be nice if the Issues List reflected what Rob's initial
proposal morphed into, and the discussion continued there. (Rob: I'll have
a try if you want...)

2. oa:Set and probably oa:List can profitably be applied to  a collection
of oa:Annotations.  The use case is actionable annotations that are
delivered to remote agents,  and upon which collections of expected actions
must taken, possibly in a prescribed order.  This is particularly needed
when actionable annotations will generate response annotations (e.g. "Agent
Smart accepted all of your corrections in the oa:Set :mySet1 except the
oa:item :mySet1.item10.").  If a collection of actionable annotations
travels in a disconnected fashion, the annotation publisher can not easily
(at all?) convey that a coordinated action is desired.  There may be an
argument for ao:XOR on collections of annotations also.  It's likely that
none of these collection types should be restricted to Target, Body, and
Specifiers, as is perhaps being suggested in [1]

3.  Probably oa:List objects cannot(?) survive being put in a triple store,
since order of identified nodes is not defined in the graph. [2] is a
proposal to address the issue, but it is unclear how much traction it has.
This means that  processing order for oa:List will depend on the
serialization, not on the RDF.  I vaguely recall this was raised in
Chicago, perhaps tabled for more discussion.
