Objectives • To understand what metadata standards are • To explore the need for metadata standards • To discuss metadata standards in the UK public sector
What are Metadata Standards? • Standardised descriptions of information items … • … in a structured record … • … with a consistent format
What You Can See • Photo • Amphitheatre • What You Can’t See • Location • When it was taken • Publisher, who has the IP rights • Title • Interesting trivia • Subject
Metadata standards address three main concerns: • Efficiency of retrieval • Management of information • Interoperability
Metadata Standards • Dublin Core Metadata Initiative • e-Government Metadata Standard (e-GMS)
Dublin Core Metadata Initiative • The original need • The original standard • ISO 15836
15 Core Elements • Title Creator • Subject Description • Publisher Contributors • Date Type • Format Identifier • Source Language • Relation Coverage • Rights
e-Government Metadata Standard (e-GMS) • Why does the UK public sector need a metadata standard? • Efficiency, sharing and re-use • Electronic records management systems • Legislative requirements • Transformational Government objectives
From Dublin Core to e-GMS • DC as foundation of e-GMS • e-GMS developed to recognise government needs • Mandated by e-Government Interoperability Framework (e-GIF) • e-Government Unit, Cabinet Office
e-GMS elements • Title Creator Addressee • Subject Description Aggregation • Publisher Contributor Audience • Date Type Disposal • Format Identifier Location • Source Language Mandate • Relation Coverage Preservation • Rights Accessibility Status • Digital signature
Mandatory • Creator Date Subject Title • Mandatory if applicable • Accessibility Identifier Publisher • Recommended • Coverage Language
Subject Element and the Integrated Public Sector Vocabulary (IPSV) • 3,080 preferred terms and 4,843 non-preferred terms • Hierarchical tree structure (interactive search feature)
Future Developments & Maintenance Principles • E-Government Unit endeavour not to: • Remove any elements or refinement (if removal is unavoidable, a warning will be given by deprecating a term first) • Rename any elements or refinements • Add new elements that could contain values contained in the existing elements
Summary • e-GMS in the UK public sector… • Enables the identification of individual documents • Assists in the retrieval and management of documents • Fosters interoperability between different systems
