[OAI-implementers] resumptionToken and metadataPrefix

[Tim Brody]

Hi,

ResumptionToken is *exclusive* - an OAI-compliant harvester must not supply
a metadataPrefix with a resumptionToken.

(As has been mentioned in the past by Herbert, if a prefix could be
supplied, the query could be changed, therefore the result set would be
inconsistent)

If a repository requires a metadataPrefix it isn't OAI-compliant, so either
contact the repository administrator to fix it, or you'll need to code an
explicit "work-around" for broken implementations.

All the best,
Tim.
