Subject Element and the Integrated Public
Sector Vocabulary (IPSV)
• 3,080 preferred terms and 4,843 nonpreferred 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
