Okay not to throw a wrench in here, but another thing I get questioned
about regularly is how does one fine an analytical resources/tool/etc.
Like now we have at the one ST registry site a pointer to client
resources (very limited set) separate. This has been discussed many
times abstractly, and since there is such a limited set not too much of
a pressing point.
Are there plans to 'register' and characterize tools and if so are they
services, interfaces (probably not), and where does the line get drawn
between apps/clients and such things?
Perhaps this is a separate deal from the resource/service/interface
discussion but often a question we've received from registry users.

Okay, this is a pretty good cut. The different interfaces provide
to the same logical functionality. The service, then, is defined by its
behavior and some abstract description of its inputs and outputs. In
specific terms, different services will be described by different
"capability" metadata. This is all consistant with the current XML

I think so.
