  1. Modelling Intellectual Processes: The object-orient FRBR Model CIDOC 2006 Martin Doerr Center for Cultural Informatics Institute of Computer Science Foundation for Research and Technology - Hellas Gothenburg, Sweden September 12, 2006

  2. The FRBR - CRM HarmonizationLibrary and Museum Information • The CIDOC Conceptual Reference Model (CRM) is a core ontology aiming to integrate cultural heritage information. • The Functional Requirements for Bibliographic Records (FRBR) is a core ER model to integrate library information. • Libraries document literature in order to facilitate access to it. • Museum objects are referred to and published in literature. Literature describes the museum objects, their context and theories about and related to them. Literature describes subjects that are exemplified or illustratedby museum objects. • Museum documentation classifies and describes museum objects, their context and relevance. It refers to literature. Museums produce regularly literature. Libraries may also produce literature. • Libraries may document and curate rare objects as museums do.

  3. The FRBR - CRM HarmonizationLibrary and Museum Information • Documentation tasks of museums and libraries overlap. • Museum and library information has complex interrelations. Museum and library information overlaps, and otherwise is different. • Museums and libraries can learn from each others methodology. • Research needs an integrated view on museum and library information • There was no common conceptual model or machine-readable language to integrate rich museum and library information. DC is a good format, but often too simple. MARC is detailed, but used only by libraries. There are the models of FRBR, FRAD, CIDOC CRM.

  4. The FRBR - CRM HarmonizationThe Harmonization Project • Formation in 2003 of the International Working Group on FRBR/CIDOC CRM Harmonisation: • A collaboration of CIDOC CRM-SIG and the IFLA FRBR Review Group. • To express the IFLA FRBR model with the concepts, ontological methodology and notation conventions provided by the CIDOC CRM. • To facilitate the integration, mediation and interchange of bibliographic and museum information. • After 7 meetings, a first complete draft of “FRBROO” for public comment. Definition available as text in the format of the CRM. • Other forms: A comprehensive text with all related CRM definitions and complete mappings FRBRER to FRBROO, OWL/RDF files, VISIO graphics. • Work continues with FRAR (Functional Requirements for Authority Records)

  5. The FRBR - CRM HarmonizationCRM • The CIDOC Conceptual Reference Model (CRM) • developed since 1996 by CIDOC / ISO TC46, ISO 21127 by 2006 • a core ontology aiming to integrate cultural heritage information • Innovations: • centre descriptions not around the things, but around the events that connect people, material and immaterial things in space-time. • explicit description of the discourse on relations between identifiers and the identified. • typologies modeled both as classification means and as objects of the cultural-historical discourse. • Lacks: a model of intellectual work

  6. The FRBR - CRM HarmonizationFRBR • The Functional Requirements for Bibliographic Records (FRBR) • developed 1992-1997 by IFLA, now being complemented by the Functional Requirements for Authority Data (FRAD) • A core ER model to integrate library objects by content relation • Might result in a new library practice • Innovations: • Definition of stages/ abstraction levels of intellectual products: Work, Expression, Manifestation, Item. • Clusters publications and items around the notion of derivation and common conceptual origin across stages / abstraction levels. • Lacks: any explicit notion of the processes behind. Partially ambiguous definitions (overgeneralization).

  7. The FRBR - CRM HarmonizationFRBR : Abstraction Levels has part has a complement has a successor has a summary has a supplement has a transformation has adaptation has an imitation “a distinct intellectual or artistic creation… there is no single material object one can point to as the work...” Work isrealized through (is a realization of) has part “the intellectual or artistic realization of a work in the form of alpha-numeric, musical, or choreographic notation, sound, image, object, movement, etc” has a complement has a successor has a summary has a supplement has a transformation has adaptation has an imitation Expression isembodied in (is the embodiment of ) “the physical embodiment of an expression of a work…all the physical objects that bear the same characteristics… …may be only a single physical exemplar…” has part Manifestation isexemplified by (exemplifies ) has part “a single exemplar of a manifestation...” Item

  8. The FRBR - CRM Harmonizationclarification of Work concepts • The substance of Work is concepts (the idea). • Only through the comprehension of the concepts derivation is possible. • Individual Work: A self-contained set of concepts (“completed”) • Complex Work: Continuation (possibly by others), complements, alternatives, translations ! • Container Work: Incorporating unaltered work. • The Publisher’s work is a Work ! • Serial Work: Coherent, open ended series/serials E28 Conceptual Object F1Work F46 Individual Work F48 Container Work F21 Complex Work F43 Publication Work F22 Serial Work

  9. The FRBR - CRM Harmonizationclarification of Expression concepts • The substance of Expression is signs (the “text”). • An Expression can be “complete”. • The kinds of signs/features that identify an Expression depend on the function. • Self-Contained ~: “Complete” – either according to author or unfinished. • Fragment ~: Any piece, in relation to the whole. • Publication ~: Text, layout, illustrations,… E73 Information Object F2 Expression F23 Expression Fragment F20 Self-contained Expression F41 Publication Expression

  10. The FRBR - CRM HarmonizationWork and Expression Self-Contained Expression = Evidence of Individual Work Complex Work = Coherent set of Individual Works (not “complex”) F1 Work F21 Complex Work R12 has member (is member of) R12 is realized in (realises) F46 Individual Work F46 Individual Work F46 Individual Work F46 Individual Work R56 is realized in (realises) R56 is realized in (realises) F20 Self-Contained Expression F20 Self-Contained Expression F20 Self-Contained Expression F20 Self-Contained Expression

  11. The FRBR - CRM Harmonizationclarification of Manifestation concepts E55 Type immaterial Manifestation Product Type is a class of like items (the publication) F3 Manifestation Product Type E24 PhysicalMan-Made Stuff E84 Information Carrier An Item is single exemplar of a Manifestation Product Type. Manifestation Singleton An Manifestation Singleton is an “original”. It may be a feature (e.g. Inscription) Item material

  12. The FRBR - CRM HarmonizationThe “Externalization”, material / immaterial E65 Creation E12 Production E28 Conceptual Object F31 Expression Creation F40 Carrier Production Event F3 Manifestation Production Type R9 comprises carriers of R41 produced (was produced by) R49 created a realization of R22 created E24 Physical Man-Made Thing F1 Work E84 Information Carrier F2 Expression R45 created R10 belongs to type R56 is realized in F23 Expression Fragment F21 Complex Work F46 Individual Work F20 Self Contained Expression F4 Manifestation Singleton F5 Item

  13. The FRBR - CRM HarmonizationConception and “Externalization” F1 Work R21 initiated P4 has time-span F30 Work Conception E52 Time P14 carried out by P7… E39 Actor P4… P14 carried out by E65 Expression Creation E53 Place P7 took place at R49 created a realisation of R22 created R45 created F2 Expression F4 Manifestation Singleton Work elaboration Work conception Expression creation time produces a work produces an idea Produces (simultaneously) an Expression and a Manifestation-Singleton

  14. The FRBR - CRM HarmonizationWork and Expression – short-cuts F1 Work A has part F1 Work A.2 has part R49B was realised through (created a realisation of) F46 Individual Work A.2.1 R56 is realised in (realises) F31 Expression Creation A.2.1 R22created (was created by) R13 is realized in (realises) F2 Expression A.2.1

  15. The FRBR - CRM HarmonizationContainer Work – What is the Expression? The collected expressions are integral part of the container The Container Work adds Expression: may cause Work with empty expression! F48 Container Work & F46 Individual Work F48 Container Work R13 is realized in (realises) R13 is realized in (realises) Overall Expression Additional Expression <Additional Expr.> R13 is realized in R13 is realized in Expression of Work X Work X Expression of Work X Work X Expression of Work Y Expression of Work Y consistent inconsistent

  16. The FRBR - CRM HarmonizationPublication Work - An Identity Crisis F43 Publication Work F21 Complex Work “Oliver Twist” Publication Concept “Oliver Twist” Idea Publisher’s Level R12 has member (is mem ber of) F46 Individual Work R56 is realized in (r ealises) “Oliver Twist” Completed F45 Publication Event R56 is re alized in (real ises) “Oliver Twist” published! R55 created produ ction plan (was created by) R11B forms part of (is composed of) F41 Publication Expression F20 Self-Contained Expression “Oliver Twist” Publication content “Oliver Twist” Text F39 Production Plan “Oliver Twist” Plan CLR5 should carry (should be carr ied by) P128B is carried by (carries) R39B was followed by (foll owed) F3 Manifestation-Product Type R38 produced things of type (was produced by) “Oliver Twist” Publication Author’s Level R10B is type of (belongs to type) F4 ManifestationSingleton F40 Carrier Production Event “Oliver Twist” Manuscript R41 produced (was produced by F5 Item “Oliver Twist” Printing “Oliver Twist” 20th Book

  17. The FRBR - CRM HarmonizationManifestation Product Type - a Metaclass ! E55 Type Metaclasses E19 Physical Object F3 Manifestation Product Type R9 comprises carriers of F5 Item instances CLP57should have number of parts Inherits from E19 Physical Object: P57 has number of parts P57 has number of parts E60 Number ISBN:960-86830-0-9 Items are seen as instances of a particular Manifestation Product Type. This is simulated by property R9 “R9 comprises carriers of” = instances CPL57 should have number of parts particulars 1 … 2 Individual copies n 3 2 P57 has number of parts

  18. The FRBR - CRM HarmonizationEquivalence Physical - Electronic Publishing Physical Publishing Electronic Publishing F45 Publication Event F45 Publication Event makes accessible R55 created produ ction plan (was created by) F41 Publication Expression R55 created produ ction plan (was created by) F41 Publication Expression F39 Production Plan CLR5 should carry (should be carr ied by) F39 Production Plan R39B was followed by (foll owed) F3 Manifestation-Product Type downloads R39B was followed by (foll owed) R38 produced things of type (was produced by) R5 carri es (is carried by) R10B is type of (belongs to type) F40 Carrier Production Event R41 produced (was produced by) F40 Carrier Production Event R41 produced (was produced by) F5 Item F5 Item F44 ? “copy on local carrier” “Result of an industrial process”

  19. The FRBR - CRM HarmonizationReproduction E12 Production F44 Reproduction Event R59 reproduced (was reproduced by) R59 reproduced (was reproduced by) E84 Information Carrier E84 Information Carrier “In general, the copy will have different attributes from the original… F44 Reproduction Event and F40 Carrier Production Event are not declared as disjoint…”

  20. The FRBR - CRM HarmonizationHow to identify Work? F3 Manifestation Product Type R32 assigned (was assigned by) F4 Manifestation-Singleton F36 Representative Manifestation Assignment R3 has representative manifestation product type (is representative manifestation product type for) R7 has representative manifestation-singleton ( is representative manifestation singleton for) R17 carried out by (performed) R31 assigned to (was assigned by) F28 Bibliographic Agency F2 Expression R34 assigned (was assigned by) R16 carried out by (performed) F37 Representative Expression Assignment R2B has representative expression (is representative expression for) R33 assign to (was assigned by) F21Complex Work

  21. The FRBR - CRM HarmonizationLibrary identifiers have structuring rules R26 used constituent (was used in) P1B identifies (is identifies by) E1 CRM Entity F13 Name = E41 Appellation R51consists of (forms part of) F14 Identifier R25 assigned (was assigned by) F33 Identifier Assignment R52B used rule (was the rule used in) F16 Identifier Rule R24 assigned to (was assigned by)

  22. The FRBR - CRM HarmonizationSummary of new Activity Concepts F37 Representative Expression Assignment E13 Attribute Assignment F36 Representative Manifestation Assignment E7 Activity F33 Identifier Assignment E15 Identifier Assignment F45 Publication Event E65 Creation F30 Work Conception F31 Expression Creation E83 Type Creation F44 Reproduction Event E12 Production E11 Modification F40 Carrier production Event

  23. The FRBR - CRM HarmonizationResults summary • Topics solved: • Explicit modeling of the processes behind FRBR attributes. • The substance of Work, Expression and Manifestation • Conception of a Work. What is its identity, its parts? Can a work be continued by other persons? Can it contain other Work, and in which sense? • Expression fragments, parts, aggregates and collections: criteria of completeness, containment, reuse and intellectual contribution. • What is the contribution and product of thepublisher. • What is the first realization of a work in a symbolic form? What is the role of a manuscript, of a digital file, a written diskette in that process? • The equivalence of electronic and material publishing.

  24. The FRBR - CRM HarmonizationConclusions • The combined model CRM – FRBROO: • Is a coherent model of museum and library conceptualization • On one side enriches the CIDOC CRM with notions of the stages of intellections creation and refines its model of identifiers and the associated discourse. • On the other side, it makes available to FRBR the general model of historical events of the CRM. • clarifies and makes explicit many notions more vaguely specified in FRBR • Further work: • FRAD (Authority Data), • modeling equivalence with performing arts.
