e-GMS

The e-Government Metadata Standard , e-GMS , is the UK’s e-Government Metadata Standard. It defines how publicly available information is easily managed, found and shared.

The metadata standard is an application profile of the Dublin Core Metadata Element Set and consists of mandatory, recommended and optional metadata elements such as title, date created and description.

The e-GMS is part of the e-Government Metadata Framework (e-GMF) and eGovernment Interoperability Framework (e-GIF). [1] [2] [3] The standard provides a basis for the adoption of XML schemas for data exchange. [4]

Metadata elements

The current standard defines twenty-five elements. Each has a formal description (mandatory if applicable, mandatory if applicable, recommended or optional):

  1. Accessibility (mandatory if applicable)
  2. Addressee (optional)
  3. Aggregation (optional)
  4. Audience (optional)
  5. Contributor (optional)
  6. Coverage (recommended)
  7. Creator (mandatory)
  8. Date (mandatory)
  9. Description (optional)
  10. Digital signature (optional)
  11. Disposal (optional)
  12. Format (optional)
  13. Identifier (mandatory if applicable)
  14. Language (recommended)
  15. Location (optional)
  16. Mandate (optional)
  17. Preservation (optional)
  18. Publisher (mandatory if applicable)
  19. Relationship (optional)
  20. Rights (optional)
  21. Source (optional)
  22. Status (optional)
  23. Subject (mandatory)
  24. Title (mandatory)
  25. Type (optional)

Each element has a statement of purpose, notes, clarification, refinements, examples of use, HTML syntax, encoding schemes and mappings to other metadata where applicable. [5]

Development

The first version of the standard comprising simple Dublin Core elements was first published with the e-GMF. E-GMS was published as a separate document by the Office of the e-Envoy in April 2002 and contained twenty-one elements. [6] Version 2 was released in December 2003 and added separate elements for Addressee, Aggregation, Digital Signature and Mandate. [7] Version 2 added aussi Further Refinements and Introduced the e-GMS Audience Encoding Scheme (e-GMSAES) and e-GMS Type Encoding Scheme (e-GMSTES). [8] [9] Version 3 was released in April 2004 and incorporated PRONOM within the format and preservation elements. [10] The most recent version, 3.1, Was published in August 2006 by the Cabinet Office e-Government Unit following the Office of the e-Envoy. [5] It now forms part of the UK Government’s Information Principles , supporting the principle that “Information is standardized and linkable”. [11] Responsibility for maintenance and development of the standard has been moved from central to local government.

Subject metadata and the Integrated Public Sector Vocabulary (IPSV)

The Integrated Public Sector Vocabulary is a vocabulary for describing subjects and was first published in April 2005, building on developments of the subject element with version 3.0 of e-GMS. It merged three earlier lists: the GCL ( Government Category List ), LGCL ( Local Government Category List ) and the seamlessUK taxonomy. [12] [13] It had 2732 preferred terms and 4230 non-preferred. [10] [14]

The current version, version 2, was released in April 2006. It is much bigger, with 3080 preferred terms and 4843 not-preferred terms and covers internal-facing as well as public-oriented topics. The Internal Vocabulary was released as a separate subset containing 756 preferred terms and 1333 non-preferred terms. An abridged version of the IPSV was also released containing 549 preferred terms and 1472 non-preferred terms and remains compliant with the e-GMS. [15]

The Public Sector Information Domain – Metadata Standards Working Group Subsequent to Recommend this change to eGMS on the subject of metadata from October 2012:

Where you identify value in using the subject element of the metadata it should be populated from a controlled vocabulary that is used consistently across the sector to which the information relates. In preference, vocabularies should be published according to SKOS and publicly available for free re-use, which then allows tagged information to be further grouped, and associated, by an agent. SKOS also encourages cross-references to be made across otherwise unconnected vocabularies.

This change in advances in the use of eGMS, and modern approaches to cataloging and cross-referencing information against evolving terminologies.

IPSV is no longer directly referenced and mandated within eGMS, allowing the publisher to consider the subject vocabulary that best describes their business. Therefore, IPSV remains an option.

The Local Government Association esd-toolkit HAS since continued hosting IPSV and current URIs Will Remain valid. [16] [17]

Mapping

E-GMS has been mapped to the IEEE / LOM . [5] IPSV has been mapped to the Local Government Classification Scheme. [18]
