  1. Mapping MARC to FRBR

  2. Functional Analysis of the MARC 21 Bibliographic and Holdings Formats Prepared for the Network Development and MARC Standards Office Library of Congress by Tom Delsey February 2002 www.loc.gov/marc/marc-functional-analysis/home.html

  3. BackgroundObjectives and Approach • Clarify the relationship of MARC 21 to the FRBR and AACR models • Extend the FRBR model to account for all data elements in MARC 21 • Relate individual data elements to user tasks • Highlight key issues for future development of the MARC 21 formats

  4. WORK EXPRESSION MANIFESTATION ITEM PERSON CONCEPT CORPORATE BODY OBJECT EVENT PLACE FRBR Model IFLA Study Group on the Functional Requirements for Bibliographic Records

  5. Extending the FRBR ModelAdditional attributes defined for FRBR entities WORK EXPRESSION MANIFESTATION ITEM PERSON CONCEPT CORPORATE BODY OBJECT EVENT PLACE

  6. Extending the FRBR ModelAdditional entities related to work WORK TASK WORK UNIT PROJECT PROGRAM CONTRACT CURRICULUM GRANT STUDY PROGRAM

  7. Extending the FRBR ModelAdditional entities related to item ITEM ACTION AUTHORITY POSITION

  8. Extending the FRBR ModelAdditional processing entities RECORD SEGMENT FIELD DATA ELEMENT

  16. Problematic Mappings (1) Coded data elements containing a mixed set of values • Coded values defined for a single fixed-length data element map to different attributes/entities • Form of item (006/008) • microfilm/microfiche/microopaque = form of carrier • large print = type size • regular print reproduction = relationship • Type of visual material (006/008) • game, picture, chart, etc. = form of work • graphic, model = form of expression • flash card, slide, etc. = form of carrier

  17. Problematic Mappings (2) Coded data elements defined by data type • Data elements defined by data type may map to different attributes/entities • Date 1 / Date 2 (008) • date of publication/distribution (manifestation) • date of manufacture (manifestation) • date of expression • Place of publication (008) • place of publication/distribution (manifestation) • place of manufacture (manifestation)

  18. Problematic Mappings (3) Variable data elements defined by function/form • Subfields defined by function or form may map to different attributes/entities • Linking entry fields (760-787) • ‡a (main entry) = person/corporate body/work • Subject added entry – topical (650) • ‡a (topical term) = concept/object/event/place

  19. Problematic Mappings (4) Variable data elements comprising multiple attributes • Subfields defined to encompass more than one discrete data element • Physical description (300) • ‡e (other physical details) = physical medium / capture mode / playing speed / groove width / kind of cutting / tape configuration / kind of sound / special reproduction characteristics / colour / polarity / presentation format / file characteristics • Original version note (534) • ‡t (title statement) = title of manifestation + statement of responsibility • ‡e (physical description) = form of carrier + extent of carrier + dimensions of carrier, etc.

  20. Problematic Mappings (5) Variable data elements defined in non-specific terms • Subfields defined as “catch alls” • Miscellaneous/qualifying information (1XX/2XX/6XX/7XX/8XX) • 1XX/6XX/7XX/8XX ‡g (miscellaneous information) • 210/222 ‡b (qualifying information) • 760-787 ‡c (qualifying information) • Additional information (3XX) • 307 ‡b (additional information) • Remainder of title (2XX) • 242/245/246/247 ‡b (remainder of title) • Note/display text (5XX/760-787/85X/86X/87X) • 500 ‡a (general note) • 760-787 ‡n (note) • 852/856/863/866/867/868/876/877/878 ‡z (public note)

  21. Problematic Mappings (6) Data elements requiring clarification • Definition of MARC data element needs clarification to confirm mapping • Confirm applicability to defined attribute • Festschrift (006/008 Books) = purpose of work? • Patent number (013 ‡a) = manifestation identifier? • Direct reference method (352 ‡a ) = file characteristics? • Determine appropriate entity/attribute • Production elements (007 MP) = ??? • Copy information (051/061/071) = ??? • Extent (583) = ??? • Level of index term (653/01) = ???

  30. ConclusionsCompatibility, conversion, correlation • High level of compatibility between MARC 21 and the FRBR model • Conversion from MARC 21 to an FRBR record structure requires complex processing routines • Residue of unmapped data • Hierarchical displays reflecting FRBR relationships using subset of MARC 21 data elements
