1. FAST: Faceted Application of Subject Terminology Edward T. O'Neill, OCLC Online Computer Library Center, Inc. Subject Metadata from the Other Side ASIST 2002, Philadelphia, PA November 21, 2002

2. Schema Requirements Suitable for metadata, Simpleusable by non-catalogers and in non-library environments, Semantic interoperability enabling users to search across discipline boundaries.

3. OCLC ALCTS/SAC Synergy Library of Congress OCLC Team Lynn El-Hoshy Lois Mai Chan

4. 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)

5. 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.

6. Card Format LCSH was originally created for card catalogsa 3x5 card environment, Cards required pre-coordinated vocabulary, Cards restrict the limits number of entries. Z693.5 Chan, Lois Mai.

7. 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.

9. 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.

11. Geographic name will be established and applied in indirect order, [OhioColumbus 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. FACET: Geographic

13. 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.
