Project – HILT Phase IV

High-Level Thesaurus (Phase IV)

Short Project Name: HILT IV

Programme Name: Repositories and Preservation Programme

Strand: Shared Infrastructure Services

Brief project description:
Pilot terminology service to assist users of the IE with the discovery of the appropriate resources by subject browse and search.

“‘HILT phase IV: Transition to Service Testbed and Future Requirements Study’ aims to research, investigate and develop pilot solutions for problems pertaining to cross-searching multi-subject scheme information environments, as well as providing a variety of other terminological searching aids.

HILT phase IV will build on the work of phase III by moving HILT to a transition to service phase. This will allow an initial entry-level service to be built, tested for user requirements and retrieval effectiveness, refined in line with the findings, and extended to permit the use of a range of distributed terminology services for interoperability. It will also allow an examination of the level of need and interest amongst JISC services in respect of an operational service and, if appropriate, a scoping of the costs and requirements of a future operational phase of the service.

HILT phase IV will also conduct a parallel programme of research into selected topics germane to terminology services, as well research into the costs and requirements of an initial entry-level operational service and any future extension of this. ”

Output – SAFIR: Requirements Specification – OAIS

Title: Digital Library Project (SAFIR): Requirements Specification

Pages: 5-13
Date Released: 07 March 2008

URI for Output: https://vle.york.ac.uk/bbcswebdav/xid-89716_3

Summary of contents:

This section of the specification uses the Reference model for Open Archival Information Systems (OAIS) as a basis for analysing the repositories context and creating a specific reference model on which to base the requirements specification.

The following the OAIS model the analysis considers:

  • the designated communities of the repository
  • how it aproaches different functional areas (ingest, archival storage, data management, administration, preservation planning, and access)
  • the information model and information lifecycle that has to be supported
  • issues of interoperablity and integration

Comments:

This provides an example of a lightweight use of OAIS as a method of describing and analysing the context of a repository. As such it considers the whole information lifecycle as part of the planning process.
