I think that this is essential functionality.  If we can't find annotations
for the resource(s) that are being viewed in a standard way, then we'll be
a long way from the interoperable world we all want.  Every client will
only work with their own annotation store, and we'll still be locked into
data silos.

Use cases regarding the sorts of queries that we (as a community) would
find useful seems like an essential first step.  Then we can assess whether
it has already solved the issue for us, if another party is working on it
that we could collaborate with, or if we need to do it ourselves.  The LDP
WG has been discussing search as a new deliverable in their rechartering
process, and given that they have a solid foundation of REST and JSON-LD,
it seems to me like a good route to explore first.

Agreed, and this is useful outside of discovery.   A requirement would be a
method for the publisher to let a client know where those notifications
should be sent.  The activity streams work in Social Web group seems like a
good place to start on this side.

Thanks Ray,
