UNIMARC and BC

Management of the flow of events (updates, enhancements)

Management of the database of records

Allow searching and downloading of records

• Cataloguing in Publication(CIP) type records

• Conversion on to national MARC format using USEMARCON

• Enhanced records optionally returned to publishers

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
