1 OCLC Online Computer Library Center Retrieval That Works: FRBR (Functional Requirements for Bibliographic Records) and OCLC Eric Childress OCLC Research SEALL 2006 Raleigh, NC 8 April 2006

2 OCLC Online Computer Library Center Outline Background FRBR explained FRBR applied

3 OCLC Online Computer Library Center FRBR Explained

4 OCLC Online Computer Library Center FRBR basics FRBR = Functional Requirements for Bibliographic Records Developed by cataloging experts working under the auspices of IFLA (International Federation of Library Associations and Institutions) FRBR is from a document issued by IFLA: Functional Requirements For Bibliographic Records: Final Report (1998) FRBR is a conceptual model (not a standard!) FRBR systematically models the bibliographic universe

5 OCLC Online Computer Library Center The FRBR Project Stockholm Seminar on Bibliographic Records (1990) Issued a resolution calling for the commissioning of a study to define the functional requirements of bibliographic records IFLA Study Group on the Functional Requirements for Bibliographic Records Study ( ): Against the changing environment within which cataloging principles & standards operate… Conceptualize a cataloging code- and implementation-agnostic, generalized view of the bibliographic universe Deliver ( ): A reference (i.e. conceptual) model A report: Functional Requirements for Bibliographic Records: Final Report Münich : K.G. Saur, [viii, 136 pages. ISBN X]Functional Requirements for Bibliographic Records: Final Report

6 OCLC Online Computer Library Center About the FRBR study… Primary objectives of the FRBR study: Provide a clearly defined, structured framework for relating bibliographic data to user needs Recommend a basic level of functionality for records created by national bibliographic agencies Modeling the bibliographic universe: Utilizes an entity-relationship framework: Entities = a class of things Relationships = associations among entities Attributes = characteristics of the entities

7 OCLC Online Computer Library Center Value of FRBR FRBR study process and report: Fresh look at what functions bibliographic records perform FRBR systematically models the bibliographic universe Helps us answer important questions: What information is of the most value to users of the catalog? How can that most valuable information be used more effectively? Promises to inspire next generation catalogs, etc. Illuminates user tasks Clarifies how catalogs should function

8 OCLC Online Computer Library Center The FRBR model is revolutionary. The (computer) catalogue is not seen as a sequence of bibliographic records and a replica of the traditional card catalogue, but rather as a network of connected data, enabling the user to perform seamlessly all the necessary functions. -Dr. Maja Žumer. National and University Library, Ljubljana, Slovenia

9 OCLC Online Computer Library Center FRBR Explained (in Swedish…)

10 OCLC Online Computer Library Center Four User Tasks: Find entities that match the search criteria Identify entities (confirm that the user has found what they were looking for) Select an entity that matches the users criteria Obtain access to the entity through purchase, loan, or through electronic remote access And, maybe a fifth: Navigate

11 OCLC Online Computer Library Center FRBR defines 3 groups of entities Group 1: products of intellectual or artistic endeavor that are named of described in bibliographic records work, expression, manifestation, item Group 2: entities responsible for the intellectual or artistic content, the physical production and dissemination, or the custodianship of such products person, corporate body Group 3: entities that serve as the subjects of intellectual or artistic endeavor concept, object, event, place

14 OCLC Online Computer Library Center Work Expression Is realized through Is exemplified by Item Manifestation Is embodied in A distinct intellectual or artistic creation The intellectual or artistic realization of a work The physical embodiment of an expression A single exemplar of a manifestation Group 1 Entities

15 Group 1

16 OCLC Online Computer Library Center Attributes A set of characteristics that serve as the basis for formulating queries and interpreting responses Can be either inherent or externally applied E.g., inherent: the physical medium and dimension of an object E.g., externally sourced: assigned identifiers (e. g., thematic catalog numbers for musical compositions)

17 OCLC Online Computer Library Center Attributes of Group 1 Entities Work Work title, form or genre, date, performance medium, intended audience Expression Expression title, form of the expression, language of the expression, type of score, scale of a map Manifestation Manifestation title, publisher, date of publication, form of carrier, dimensions, manifestation identifier (e.g. ISBN), terms of availability Item Location or call number, barcode, provenance, condition, access restrictions on an item

26 OCLC Online Computer Library Center Group 2 – Responsible Entities Entities responsible for the intellectual or artistic content, the physical production and dissemination, or the custodianship of such products Group 2 entities: Person Corporate Body And perhaps a third … Family

27 OCLC Online Computer Library Center Attributes of Group 2 Entities Attributes of Group 2 entities: Person Names, dates, titles or other designations Corporate body Name, number, place, date, other designation

28 From William Denton (http://www.frbr.org/)http://www.frbr.org/

29 OCLC Online Computer Library Center Group 3 - Subject Entities Entities that serve as the subjects of intellectual or artistic endeavor Group 3 entities: Concept: topical subject heading Object: name for an object Event: name for an event Place: name for a place Plus the Group 1 and 2 Entities: Works about Works/Expressions/Manifestations/Items Works about Persons and/or Corporate Entities

31 OCLC Online Computer Library Center Since the initial FRBR report… Statement of International Cataloguing Principles Approved by the IFLA Meeting of Experts on an International Cataloguging Code (Frankfurt, 2003) Statement of International Cataloguing Principles Adapts and expands the Paris Principles (1961)Paris Principles Expands scope from: Textual works to all types of materials Choice and form of entry to all aspects of bibliographic & authority records First principle remains: Serve the convenience of the users of the catalogue

32 OCLC Online Computer Library Center Working the FRBR/FRANAR framework… All work now under the FRBR Review Group:FRBR Review Group Group 1 entities [bibliographic]: The IFLA Study Group on the Functional Requirements for Bibliographic Records, Various follow-on work underway (Clarifying expression ; Clarifying FRBR for continuing resources, more…) Group 2 entities [authorities]: Functional Requirements and Numbering of Authority Records (FRANAR) Working Group Group 3 entities [subject access]: Working Group on Subject Relationships

33 OCLC Online Computer Library Center FRBR Applied

34 OCLC Online Computer Library Center Applying FRBR in services Incorporating the concepts of the FRBR model in systems: Superior presentation of search results Esp. in large files – more intuitive clustering May help streamline library cataloging Reduces repeated keying of work-related info Bibliographic & management intelligence New insights into works (e.g., OCLCs 1000 list)OCLCs 1000 list Libraries can operate at workset level (e.g., ILL)
