I assume you are referring to Z39.50 here. If so, then I would
point out that a "result set" is an ordered list of records that
satisfy particular search criteria. The records themselves can
be composed in whatever manner suits the need. Certainly the
records can be composed of elements drawn from multiple sources,
whether those had been centralized or distributed, and whether
they had common structures or not. So, melding content from an
OASIS Registry and Public UDDI is quite feasible in a Z39.50
environment. Because Z39.50 itself is silent about how melding
is to be accomplished, melding mechanisms are unconstrained.
