2 FRBR Consoidation - Why and How FRBR (1998), FRAD (2009), FRSAD (2010) 3 distinct modes Different eves of specificity Different focus Different modeing decisions Consoidation Editoria Group, Creating IFLA-Library Reference Mode (IFLA LRM) Accepted as IFLA standard on August 18, 2017 DCMI, October

3 Main differences user tasks Find, identify, seect, obtain defined by FRBR Expore added by FRSAD (to cover browsing) Justify and contextuaize in FRAD (focus on the cataoguing process) DCMI, October

4 Main differences - appeations In FRBR modeed as attributes of entities Nomen in FRSAD Name, identifier, controed access point in FRAD DCMI, October

5 Main differences - subjects Reationship ( work has as subject ) in FRBR and FRSAD Work attribute in FRAD DCMI, October

6 Main differences - reationships Different eves of specificity In FRBR and FRAD decared in one direction and with no cardinaity restrictions; domain and range not aways indicated DCMI, October

7 Goas of LRM High-eve conceptua mode Expressed in entity-reationship framework Consistent view of bibiographic universe Work informed by Research with users FRBRoo and CIDOC CRM Experiences impementing FRBR, FRAD, FRSAD Semantic Web and Linked Data context DCMI, October

8 Modeing Decisions Mode the data needed to fufi (end-)user tasks, not ibrary operations Entity-reationship modeing anguage (entities, reationships, attributes) High-eve conceptua mode Framework that enabes consistent expansions in impementations Ony high-eve attributes and reationships DCMI, October

9 LRM User Tasks Find Identify Seect Obtain Expore Confirm end-user focus of the mode Library interna processes not refected in the tasks Reworded definitions to be more genera DCMI, October

10 User Tasks: Definitions Find: To bring together information about one or more resources of interest by searching on any reevant criteria Identify: To ceary understand the nature of the resources found and to distinguish between simiar resources Seect: To determine the suitabiity of the resources found and to be enabed to either accept or reject specific resources Obtain: To access the content of the resource Expore: To discover resources using the reationships between them and thus pace the resources in a context. DCMI, October

11 Work Entities ( from FRBR group 1) The inteectua or artistic content of a distinct creation Expression A distinct combination of signs conveying inteectua or artistic content Manifestation A set of a carriers that are assumed to share the same characteristics as to inteectua or artistic content and aspects of physica form. That set is defined by both the overa content and the production pan for its carrier or carriers Item An object carrying signs intended to convey inteectua or artistic content DCMI, October

12 Entities (FRBR group 2) Agent An entity capabe of deiberate actions, of being granted rights, and of being hed accountabe for its actions Coective Agent Person A gathering or organization of persons bearing a particuar name and capabe of acting as a unit An individua human being DCMI, October

13 Entities Res and Nomen From FRSAD, but Thema is repaced with Res to avoid impicit restriction to the subject reationship Res: Any entity in the universe of discourse (=supercass of a) Nomen: An association between an entity and a designation that refers to it DCMI, October

14 New entities Pace A given extent of space Time-span A tempora extent having a beginning, an end and a duration DCMI, October

15 Attributes Data describing instances of entities Ony most important or representative attributes NOT an exhaustive isting of possibe attributes Impementations can expand by adding the attributes that are needed DCMI, October

16 Representative Expression Attribute New WORK attribute An attribute which is deemed essentia in characterizing the work and whose vaues are taken from a representative or canonica expression of the work Generay mutivaued, the attributes depend on the Category of work The specific representative expression does not have to be identified DCMI, October

17 Manifestation statement attribute Mechanism for recording data transcribed from the resource (such as edition statement, responsibiity statement ) Important for identification In addition to reationships DCMI, October

18 Core WEMI reationships DCMI, October

19 Agent reationships DCMI, October

20 Agent reationships to WEMI WORK was created by created EXPRESSION was created by created AGENT is distributed by distributes MANIFESTATION was manufactured by manufactured is owned by owns was modified by modified ITEM DCMI, October

21 Work-to-work reationships WORK has part (is part of) WORK WORK precedes (succeeds) WORK WORK accompanies / compements (is accompanied / compemented by) WORK WORK is inspiration for (is inspired by) WORK WORK is a transformation of (was transformed into) WORK DCMI, October

22 Subject and apeation reationships WORK has as subject is subject of RES RES has apeation is appeation of NOMEN has part DCMI, October

23 Overview has part is associated with is associated with TIME-SPAN is associated with has part is subject of RES is appeation of NOMEN PLACE WORK created has part is derivation of was assigned by has part precedes accompanies is inspiration for is transformation of has part was derived into is reaized through EXPRESSION is embodied in MANIFESTATION created created produced distributes owns modified AGENT isa isa PERSON has part has reproduction has aternate has reproduction is exempified by ITEM is member of COLLECTIVE AGENT has part precedes DCMI, October

24 Expanation of: Namingand identity Aggregates Serias DCMI, October

25 Fina steps FRBR RG met August 19, IFLA 2016 (Coumbus), fina decisions made foowing word-wide review comments CEG editing Fina draft reviewed again by FRBR RG Approva by Committee on Standards Approva by the PC in Wrocaw Minor editing, fina pubication in November DCMI, October

26 What next? LRM namespace Mappings FRBRoo 3.0 (LRMoo?) Extensions Types of resources Audiences Other specific needs DCMI, October
