Hopefully this may be of some use

[Robert E. Jackson]

I once worked on a project to make it easier to find which
Astronomical Telescope/Instrument is capable of obtaining
the data you wanted.

The basic notions are described in the attached DBI-VIEWGRAPH.PDF.

A possible schema description in the attached OBSERVATORY.HTML

A possible query interface is in the attached OBSERVATORY-QUERY.HTML

A possible way of making the approach scalable is described at:

     http://adass.org/adass/proceedings/adass94/jacksonr2.html

In any event, may there never be a cloudy night at the Virtual Observatory.
