So as not to assume that the WAIS request is always coming from a WWW client
I will probably do all this with a WAIS gateway and WAIS server scripts.
I hope that I can get it smart enough to then regenerate metadata files when
a hit is made. Then these could be picked up by the Multiformat Opportunity
of the client. These metadata files would then be regularly re-indexed
rather than do the keywords caper.
