[OAI-implementers] Sets in and subjects in OAI-PMH

[Jody DeRidder]

Hi Hussein--
  You have good points.  I was thinking that if we had a standardized set of
subjects/sets to use, it would be simpler/easier to analyze/divide/catalog
the records, for further use. Are there any international standards that
could be used?
