ICS-FORTH September 10, Modelling Intellectual Processes: The object-orient FRBR Model Martin Doerr Gothenburg, Sweden September 12, 2006 Corrections made 25 January 2008 Center for Cultural Informatics Institute of Computer Science Foundation for Research and Technology - Hellas CIDOC 2007

ICS-FORTH September 10,  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 illustrated by 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. The FRBR - CRM Harmonization Library and Museum Information

ICS-FORTH September 10, The FRBR - CRM Harmonization Library 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.

ICS-FORTH September 10, The FRBR - CRM Harmonization The 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 “FRBR OO ” 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 FRBR ER to FRBR OO, OWL/RDF files, VISIO graphics.  Work continues with FRAR (Functional Requirements for Authority Records)

ICS-FORTH September 10, The FRBR - CRM Harmonization CRM  The CIDOC Conceptual Reference Model (CRM)  developed since 1996 by CIDOC / ISO TC46, ISO 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

ICS-FORTH September 10, The FRBR - CRM Harmonization FRBR  The Functional Requirements for Bibliographic Records (FRBR)  developed 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).

ICS-FORTH September 10, The FRBR - CRM Harmonization FRBR : Abstraction Levels Work Expression Manifestation Item has part is realized through (is a realization of) has part is embodied in (is the embodiment of ) has part is exemplified by (exemplifies ) 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...” “the intellectual or artistic realization of a work in the form of alpha-numeric, musical, or choreographic notation, sound, image, object, movement, etc” “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…” “a single exemplar of a manifestation...” has a complement has a successor has a summary has a supplement has a transformation has adaptation has an imitation

ICS-FORTH September 10, The FRBR - CRM Harmonization clarification 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 F1 Work F15 Complex Work F14 Individual Work R1 is logical successor of (has successor) R2 is derivative of (has derivative) F20 Performance Work F21 Recording Work F16 Container Work F18 Serial Work F17 Aggregation Work R10 has member (is member of) E28 Conceptual Object F19 Publication Work

ICS-FORTH September 10, The FRBR - CRM Harmonization clarification 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,… F25 Performance Plan F2 Expression F22 Self Contained Expression F26 Recording F23 Expression Fragment R15 has component (is component of) R14 incorporates (is incorporated in) E73 Information Object R15 is fragment of (has fragment) F24 Publication Expression

ICS-FORTH September 10, The FRBR - CRM Harmonization Results 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 the publisher. — 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.

ICS-FORTH September 10, The FRBR - CRM Harmonization Conclusions  The combined model CRM – FRBR OO :  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.
