BIBLINK Core metadata

Principles• Minimum data set (Cataloguing in Print level)• Type should refine elements• BIBLINK extensions used to extend semantics• Conversions require intermediate format

Issues• Time of change for MARC formats• Need to describe journals at article level• Mapping from simple to richer format
