- UK Office for Library Information Networking
(UKOLN) - P.Miller_at_ukoln.ac.uk http//www.ukoln.ac.uk/
UKOLN is funded by the Library and Information
Commission, the Joint Information Systems
Committee (JISC) of the Higher Education Funding
Councils, as well as by project funding from the
JISC and the European Union. UKOLN also
receives support from the Universities of Bath
and Hull where staff are based.

4Standard solutions
The nice thing about standards is that
there are so many to choose from!
5So why use standards?
- Benefit from the expertise of others
- Standards are (often!) compiled by groups of very
knowledgeable people and you cant afford to
employ them all yourself - Enforce rigour in internal practices
- Standards are means of asserting control over the
resource, allowing you to manage it more
effectively - Facilitate interoperability (and access)
- Community Information originates from multiple
sources, and has many potential uses - Considered deployment of standard solutions makes
access to those resources feasible for many - A virtual CIS for London?
6What do standards do?
- Help identify whats important
- GILS Access Points
- Dublin Core elements
- Mandatory fields
- Allow for consistent use of terminology
- Name Authority Files
- Thesauri
- Lookup tables
- Enable internal and external data exchange
- Reduce duplication of effort
- Minimise (hopefully!) wasted effort
- Reflect consensus.
7What types of standard are there?
- Terminology
- East Riding of Yorkshire, not North
Humberside - City of York Council is preferred to York City
Council - Format
- Miller, A.P. 1971, not Paul Miller
- Discovery/ Semantics/ DBMS
- A gross simplification, and a very big bucket
- Creator, Subject, Title, Description
- Syntax
- ltRDF xmlns http//www.w3.org/TR/WD-rdf-syntax
gt - Transfer
- ftp//ftp.niso.org/ .
8What is Metadata?
- meaningless jargon
- ora fashionable, and terribly misused, term for
what weve always done - ora means of turning data into information
- anddata about data
- andthe name of a public servant (Tony Blair)
- andthe title of legislation (the Freedom of
Information Act).
9Metadata Standards
- Paul Miller gave a really interesting talk about
Dublin Core at the Institute of Physics in
London - In London, or in Dublin?
- About Physics and about milling?
- But what was it?

11Challenges
Opportunities
- Many flavours of metadata
- which one do I use?
- Managing change
- new varieties, and evolution of existing forms
- Tension between functionality and simplicity,
extensibility and interoperability
12Introducing the Dublin Core
- An attempt to improve resource discovery on the
Web - now adopted more broadly
- Building an interdisciplinary consensus about a
core element set for resource discovery - simple and intuitive
- crossdisciplinary not just libraries!!
- international
- open and consensual
- flexible.
See http//purl.org/dc/
13Introducing the Dublin Core
- 15 elements of descriptive metadata
- All elements optional
- All elements repeatable
- The whole is extensible
- offers a starting point for semantically richer
descriptions - Interdisciplinary
- libraries, government, museums, archives
- International
- available in more than 20 languages, with more on
the way...
14Introducing the Dublin Core
- Title
- Creator
- Subject
- Description
- Publisher
- Contributor
- Date
- Type
- Format
- Identifier
- Source
- Language
- Relation
- Coverage
- Rights

15The Dublin Core and Public Sector information
- Global/Government Information Locator Service
- Richer set of Access Points, offering enhanced
functionality within a domain - Maps well to Dublin Core
- Next version likely to entirely adopt DC1.1
semantics - Integrated well with Z39.50 for distributed
search - Australian Government Locator Service
- Based closely upon Dublin Core
- Adds information on Audience, Availability,
Mandate, and Function.
See http//www.gils.net/
See http//www.naa.gov.au/govserv/agls/
16Introducing Z39.50
- International Standard (ISO 23950)
- Originally librarycentric
- Permits remote searching of databases
- Access via Z client or over web
- Relies upon Profiles
- GILS Profile for government information
See http//www.ariadne.ac.uk/issue21/
17Z39.50 Challenges
- Profiles for each discipline
- Defeats interoperability?
- Bib1 bloat
- Largely invisible
- Seen as complicated
- Seen as expensive
- Seen as oldfashioned
- Surely no match for XML/RDF/whatever.
