## METS: Implementing a metadata standard in the digital library

## 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

## 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

## 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

## The structure of a METS file

- dmdSec

- admSec

- behaviorSec

- structMap
