• from national MARC formats back to
UNIMARC and BC
Management of the flow of events (updates,
enhancements)
Management of the database of 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
