Interoperability (1)
A diversity of formats results in interoperability problems
Possible solutions:• Crosswalks (mapping tables) - useful
for format comparisons or producing conversion programs
• Core formats - Dublin Core• Heterogeneous resource discovery
6
Interoperability (2)
MODELS project• Funded by JISC through eLib• A forum for exploring problems of
distributed heterogeneous information resources and services
• Layered approach to cross-domain resource discovery
Arts and Humanities Data Service• Implementation of layered system using
DC and a Z39.50 gateway
7
Interoperability (3)
European Dublin Core implementations:• Nordic Metadata Project
– Dublin Core toolkit
• BIBLINK: linking publishers and national bibliographic services
– EU Telematics for Libraries project– Format conversions DC/SGML - MARC
• DC-dot– Dublin Core generator
8
Interoperability (4)
ROADS and Internet subject services• Funded by JISC through eLib• Whois++ protocol• ROADS cross-searching• Centroids for query routing• Template registry and ‘cataloguing
guidelines’• Interaction with the Z39.50 protocol
9
Digital preservation (1)
A variety of preservation strategies are available - all depend upon the creation, capture and storage of metadata
Initiatives include:• RLG Working Group on Preservation
Issues of Metadata (May 1998)• Cedars project - funded by JISC under
eLib, managed by CURL• PANDORA project - National Library of
Australia
10
Digital preservation (2)
OAIS model for ‘archival information object classes’:
• Content Information• Preservation Description Information
– Reference Information
– Context Information
– Provenance Information
– Fixity Information
• Packaging Information• Descriptive Information
11
RDF
Resource Description Framework• Data model and XML based syntax• An implementation of the conceptual
‘Warwick Framework’• Modular interoperability• Useful for aggregating the different
metadata types required for managing digital information over time
12
Call to action:
Standards:• the use of standards is important
Interoperability:• needs to be a major consideration
Integration and aggregation:• metadata is a useful tool for a wide
range of tasks, resource discovery, rights management, digital preservation, etc.

UKOLN
UKOLN is funded by the British Library Research and Innovation Centre (BLRIC), the Joint Information Systems Committee (JISC) of the UK Higher Education Funding Councils, as well as by project funding from the JISC’s Electronic Libraries (eLib) Programme and the European Union. UKOLN also receives support from the University of Bath, where it is based.
