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
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

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
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)
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
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.
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)
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) = ???

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
