As a next step following documentation of the requirements for search
interoperability ( http://www.search.gov/interop/requirements.html ),
I need to construct a simple demo showing what benefits one gets from
standardized search services. The task is to do a side-by-side compare
of information searching: "with a standard" versus "without a standard".

My immediate thought is to use a metasearch example, simply because
metasearching by definition has to interface with multiple search
service instances. Here, I would use one of the tools that takes
advantage of structured information in the result sets, to make the
point that merely aggregating full-text search is just a baby step.

Please do let me know of any canned demos you may have on the shelf,
or any ideas on how best to pitch this. (Of course, hard cost/benefit
data would be nice if you have that, too!)

Thanks,

Eliot
