Retrieval That Works: FRBR (Functional Requirements for Bibliographic Records) and OCLC:  Retrieval That Works: FRBR (Functional Requirements for Bibliographic Records) and OCLC Eric Childress OCLC Research SEALL 2006 Raleigh, NC 8 April 2006 Outline:  Outline Background FRBR explained FRBR applied FRBR Explained:  FRBR Explained FRBR basics :  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 The FRBR Project:  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 (1992-1995): Against the changing environment within which cataloging principles andamp; standards operate… Conceptualize a cataloging code- and implementation-agnostic, generalized view of the bibliographic universe Deliver (1996-1998): A reference (i.e. conceptual) model A report: Functional Requirements for Bibliographic Records: Final Report Münich : K.G. Saur, 1998. [viii, 136 pages. ISBN 3-598-11382-X] About the FRBR study…:  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 Value of FRBR:  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 Slide8:  '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 FRBR Explained:  FRBR Explained (in Swedish…) Four User Tasks::  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 user’s criteria Obtain access to the entity through purchase, loan, or through electronic remote access And, maybe a fifth: Navigate FRBR defines 3 groups of entities:  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 Slide12:  From William Denton ( intellectual/ bibliographic units agents 'aboutness' Slide13:  From William Denton ( Group 1 Entities:  Work Expression Is realized through 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 Slide15:  Group 1 Attributes:  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) Attributes of Group 1 Entities:  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 Slide18:  From: OCLC FRBR work set algorithm used to cluster related WorldCat records:  OCLC FRBR work set algorithm used to cluster related WorldCat records Original English Translation Illustrated edition Abridged edition Adaptation Expressions Work¹ Work² e¹ e² e³ e¹ An example of a law title:  An example of a law title Original Microform edition 5th edition Expressions Work e¹-e3 m1 e4 Handbook of the Law of Torts William Prosser (1941) 2nd-4th editions [Braille] 5th edition, Student edition e5 Worldcat:  Worldcat Manifestations Works Items (est: holdings*1.5) 59,879,322 47,423,810 1,531,400,969 35,372,459 28,542,021 1,194,751,352 Total Print books Slide22:  Works with 1 manifestation: 87% Works with between 2 and 5 manifestations: 12% Works with andgt;
