3When to use metadata (and what to use)
- Metadata is involved throughout the digitisation
process - Images

- covers preservation, migration, formatting
- also RLG Working Group on Preservation Issues

4Why use metadata?
- Good housekeeping
- Digital preservation
- Resource discovery
- Rights management
- Turning stuff into information
5Why use metadata - good housekeeping
- The good news if you keep object records, you
already use metadata - The naming conventions used in your records
(name/subject, collector, date acquired, location
etc) relate directly to those required by a
metadata schema - The adoption of a metadata schema enforces a
standard approach to the way you collect and
manage this information
6Why use metadata - digital preservation
- Metadata preserves the core of important
contextual information alongside the object
record itself - Metadata enables a structured approach to the
management and preservation of information - Organised metadata provides a meta-collection
which can be searched and referenced more
efficiently than the original records themselves
7Why use metadata - resource discovery
- Indexed metadata provides a fast and simple means
of searching across and retrieving large numbers
of records - Standard applications of metadata (eg the RSLP
CLD/ Dublin Core) enable cross-searching between
different databases even where different field
names/ terminologies have been applied - Enables the reuse of information to suit
different priorities - Owner/manager - information management
- User/software agent - locating interpreting
information - Third-party agent - promotion re-use of
information
8Why use metadata - rights management
- Metadata preserves rights information alongside
the original object record - Enables content to be re-used and distributed in
a way that maintains the link to its original
creators - The RSLP CLD schema preserves not only the
specific contextual information but also the
relationship information - for example the
relationship between an institution, a subject
collection and a named sub-collection - In other words, metadata not only preserves
information about provenance, but also about
management and status of the collection
9Why use metadata - stuff to information
- Overall, metadata is the bridge between the
individual object record, and the much wider
context to which it belongs - Metadata enables the meaningful re-use of the raw
data. It allows users to discover, interpret and
re-purpose the information to create resources - Metadata facilitates the grouping of data into
meaningful sets of information - Metadata also preserves the necessary rights and
institutional details alongside the re-applied
information
10Why use metadata?
- At a minimum, metadata should conform to
developing e-Government and UfI metadata
standards and should be capable of supporting the
delivery of item-level Dublin Core (DC)
descriptions of all project resources. - - Source, NOF-digitise technical standards (V3.1)
11Metadata and your existing information
- There are a number of approaches to metadata
generation, depending on - which stage of information gathering/content
creation the project has reached - the technical architecture of your information
store - the schema, or conceptual architecture of your
information - the requirements of resource discovery, retrieval
and delivery - Options include
- a proprietary schema that maps directly to RSLP
CLD field names - a rich schema that can be distilled into a simple
metadata set such as Dublin Core - a Content Management System that is able to
generate metadata dynamically from object records - a CMS that is able to generate metadata in XML,
or a pure XML expression of the dataset
12Metadata and your existing information
- There are one-off tools which will distill
rich information into a simple metadata set
like Dublin Core - These run on a page by page basis
- For example, the dc.dot tool available either
as a download or direct from the UKOLN website - http//www.ukoln.ac.uk/metadata/dcdot/help/persona
l.html - Or the Metty product from ClickFire at
- http//www.clickfire.com/freeware/metty/

15but, this approach is too resource-intensive for
batch-processing of information. Where records
are held in a Content Management System, it is
much easier to generate metadata on the fly.

In other words, metadata provides the bridge
between user and information in the automated
process of resource discovery.
17Metadata and Content Management Systems
- Most current Content Management Systems will
support the publishing of metadata in a number of
formats direct from the database - It is relatively easy to distil a simple set of
metatags from the rich environment of a CMS. - The important thing is to establish a map between
your field names and the elements of the relevant
metadata set - Eg..

19Project example
- Crossroads project
- A cross-domain project to enable online access to
library, museum and archive collections in the
West Midlands - Field/database structure based on the RSLP
Collections Description Schema - CLD revised to suit the purposes of the project
but retains the core DC.elements to enable
resource discovery - Sample input form and background information now
available at http//crossroads-wm.org.uk
20dc.title
dc.identifier
dc.description
dc.coverage
dc.language
And so on. The form is designed using the RSLP
CLD as a basis, which enables it to retain
sufficient granularity to describe the
collections and relationships, but is also
capable of exporting a simplified set of
information based on the DC element set.
21e-Government and metadata
- e-Government Interoperability Framework (e-GIF)
specifies protocols and standards for
interoperability between public-sector services
online - Full documentation available at
http//www.govtalk.gov.uk - Provides a Government Category List (GCL) now
published in full, intended for use with the
Subject element of the e-Government Metadata
Standard - Standard arises from the e-Government Metadata
Framework. This document specifies the standard
approach to metadata, including the role of
Dublin Core, for public-sector bodies - NOF -digitise projects will need to familiarise
themselves with the e-GMF
22e-Government and metadata
- UfI (learndirect) implementation standards
- Specified in NOF-digi technical standards
- Provide information and guidance of relevance to
the re-use of your content for lifelong learning - Full documentation available at
