status, future developments

EDLproject Workshop, National Library of
Austria, 27th and 28th November, 2006
2
Background

• Importance of metadata interoperability for the
  development of a european digital library
• EDL project (WP1, task 4) first step towards
  metadata interoperability
• Building on how metadata has been standardised
  within The European Library
• Can TEL metadata models be extended to allow
  interoperability between other types of metadata?

3
Introduction

• What types of metadata are used in The European
  Library?
• How is this metadata used within The European
  Library?
• How is this metadata managed?
• Can these management models be extended to
  metadata from eContentplus projects?

4
Metadata in The European Library

• Two types of metadata in The European Library
• Metadata about the collection itself
• Collection level descriptions
• Metadata about the objects themselves Metadata
  records / object level metadata

5
Collections metadata

• Help users to select collections
• e.g. title, description logo of the collection
• Available in multiple languages
• Standardised
• TEL Application Profile for Collections
• NISO Collection Description Specification
• Submitted / edited via a web form
• Stored in XML format

6
Help users to select collections

• Encourage users to select collections with
  relevant content before searching
• Optimal searching up to 15 collections
• Browse collections by subject
• Search collections by description
• Browse all collections

Collection title, description logo

Collection metadata questions

• Do you have collections?
• Do you already have metadata descriptions of your
  collections?
• How do you store your collection descriptions?
• What collection description standards do you use?

18
Objects metadata

• The EL portal searches the local databases of
  partner libraries
• Or records harvested into central index
• Metadata records converted to TEL Application
  Profile for objects
• The metadata records can then be displayed in The
  European Library
• Provide access to the digital item or object
• Link to record in native interface

19
Object level metadata

• Search for

Objects metadata questions

• Do you have objects?
• Do you already have metadata records for these
  objects?
• What metadata format are these records in?
• Can you provide individual URLs for these
  objects?

27
Managing Metadata

• The European Library Application Profiles
  developed during the TEL project
• Based on Dublin Core Libraries Application
  Profile (DC-Lib)
• Two TEL application profiles
• TEL AP for collections
• TEL AP for objects
• All terms stored and described in The European
  Library Metadata Registry

28
The TEL Metadata Registry

• Place to store all the terms used in both
  application profiles
• Place to describe the terms
• Place to provide guidance on how they may be used
• Application Profiles are not static need to be
  reviewed and updated
• Development process part of registry
• Managed by the TEL Metadata Working Group

Extending the TEL Metadata Registry

• Need for metadata from eContentplus projects
  interoperable
• Move towards the development of a european
  digital library
• Initial research is being undertaken as part of
  EDLproject (WP1, task 4) www.edlproject.eu
• Extend the TEL Metadata Registry to include
  metadata elements for eContentplus collections.

31
Extending the TEL Metadata Registry

• Working with content partners from other
  eContentplus funded projects???
• Investigate metadata formats currently used in
  these projects.
• Map metadata elements onto the TEL Application
  Profiles.
• Add additional elements as required.
• Pilot providing access to non-library collection
  via the EDLproject test portal.
• Moving towards the development of a European
  Metadata Registry
