It depends *who* the users are - one community of users we have around
Oxford are cataloguers (about 500 of them). Our cataloguing client
currently uses Z39.50 and the Z39.50 extended update service, but
there's no reason why it shouldn't use SRW and SRW-Update in a future
For such people who eat sleep and dream MARC tags, formatting a query in
MARC comes much more naturally that formulating dublin core queries.
Especially if what they really want to search for are examples are where
someone else has catalogued a record which uses a 852$x linking field to
a 946 field. Or what the 652$v looks like if the 652 indicator1 is set
to 6, or some other esoteric cataloguing issue etc. etc.
