METS: Implementing a metadata standard in the digital library

1
METS Implementing a metadata standard in the
digital library

• Richard Gartner
• Oxford University Library Services
• rg_at_bodley.ox.ac.uk

2
The lack of a standard what it mean for the
digital library

• poor cross-seaching
• limited interchange facilities
• metadata tied to proprietary packages
• consequent obsolescence and costs of conversion

3
Three types of metadata

• Descriptive information about intellectual
  content (analogous to standard catalogue record)
• Administrative information for handling,
  maintenance and archiving of object
• Structural description of internal structure of
  object

4
METS Metadata Encoding and Transmission
Standard

• Produced by Library of Congress Standards Office
  and Digital Library Federation
• Provides framework for holding all types of
  metadata for digital object
• Written in XML
• Does not prescribe content of metadata, but
  recommends a number of schemes for this
