schema requirements
Schema Requirements
  • Suitable for metadata,
  • Simple—usable by non-catalogers and in non-library environments,
  • Semantic interoperability enabling users to search across discipline boundaries.

options for metadata
Options for Metadata

We were limited to three basic choices in selecting an indexing/subject heading schema for metadata:

  • The use an existing schema(s),
  • Adapt or modify an existing schema,
  • Develop new schema(s).

We elected to adapt the Library of Congress Subject Headings (LCSH)

advantages of lcsh
Advantages of LCSH
  • Rich vocabulary covering all subject areas,
  • It has the strong institutional support of the Library of Congress,
  • Synonym and homograph control,
  • Has been extensively used by libraries, contained in millions of bibliographic records,
  • Has a long and well-documented history.

Card Format
  • LCSH was originally created for card catalogs—a 3x5 card environment,
  • Cards required pre-coordinated vocabulary,
  • Cards restrict the limits number of entries.
objective of fast project
Objective of FAST Project
  • Develop a new subject heading schema by faceting LCSH that:
  • Is easy to use, understand, and maintain,
  • Is suitable for metadata,
  • Minimizes the construction of headings,
  • Simplifies the syntax,
  • Retains the richness of the vocabulary,
  • Is upwardly compatible with LCSH.

facet topical
FACET: Topical
  • LCSH main headings from topical headings (650),
  • All associated general ($x) subdivisions from any type of LCSH heading,
  • Period subdivisions containing topical aspects from any type of LCSH heading,
  • Hierarchy (Subdivisions) is retained within facets.
fast topical headings
FAST: Topical Headings

Industrial project management—Data processing

Colombian poetry

Blacksmithing—History

Epic literature—History and criticism

Pets and travel

Quartets (Pianos (2), percussion)

Natural gas pipelines—Economic aspects

School psychologists

Blood banks

Loudspeakers—Design and construction

facet geographic
FACET: Geographic
  • Geographic name will be established and applied in indirect order, [Ohio—Columbus not Columbus (Ohio)],
  • First level geographic names will be limited to names from the Geographic Area Codes table (e.g., Ohio, France, Great Lakes, etc.) Other names will be entered as subdivisions under the smallest first level name in which it is fully contained (North America—Maya Forest)
  • Geographic Area Codes will be added to all authority records for geographic names,
  • Information from the Geographic Names Information System (GNIS) including feature type, county, latitude, and longitude will be added to geographic authority records.

authorities
Authorities
  • A proposal to modify the MARC 21 bibliographic and authority formats to accommodate FAST has been approved by MARBI,
  • Authority records will be created for all FAST headings except chronological— chronological authorities will be created only when required for references,
  • Approximately 2 million FAST authority records will be created in Phase I.
