Working Group on FRBR/CRM Dialogue

Established: 2003

Tasks: in cooperation with the CIDOC CRM Special Interest Group, prepare an object-oriented formulation of FRBR (FRBRoo) that is a compatible extension of the CIDOC Conceptual Reference Model (CRM).


CIDOC CRM is the conceptual reference model for museum information, expressed in object-oriented formalism. Originally developed by the International Committee for Documentation of the International Council of Museums (ICOM CIDOC), it has now become an ISO standard (ISO 21127:2006).

The idea that both the library and the museum communities could benefit from harmonizing their conceptual models was first expressed in 2000, on the occasion of the ELAG Conference (European Library Automation Group). However, it was not until 2003 that a joint IFLA/CIDOC CRM SIG group was formed to that effect.

The objective is to produce an object-oriented version of FRBR (currently referred to as "FRBRoo") which would:

  • retain basically the same conceptualization as in FRBRer (i.e., the original, entity-relationship formulation of the FRBR model)
  • refine that conceptualization when needed for the sake of harmonization with CIDOC CRM
  • benefit from the robust formalization of CIDOC CRM
  • enrich CIDOC CRM with a conceptualization of bibliographic information, and FRBR with a conceptualization of museum information
  • be likely to be "plugged" into CIDOC CRM in order to result in an overall conceptual model for bibliographic and museum information
  • lend itself, thanks to its object-oriented formulation, to use with RDF (Resource Description Framework) in mediation systems (and other possible usages) among repositories of bibliographic and museum information, and in so-called "Semantic Web" technologies (and any kinds of technologies that are based on ontologies).
