Protocols are not applications. Protocols enable services on which
applications are built.

I think that if this working group had 5 or 10 specific scenarios
that illustrate the problems we're trying to solve, it would help
focus the discussions.

I'll start with this example...

Bob has a citation for a paper, giving author, title,
and date of publication. He knows it's available on
the internet somewhere, but he doesn't know where.
Certainly this information is enough to locate the
paper (perhaps a few keywords like "high energy physics"
would help seed the search...). Given sufficient compute
resources and connectivity, he should be able to
find the paper in an automated fashion.
