Three of the Four FRBR Group 1 Entity Types are Roles, not Types

Allen Renear and David Dubin

(Submission #48)


Summary

We examine the conceptual model of the “bibliographic universe” presented in IFLA’s Functional Requirements for Bibliographic Records (FRBR) and argue, applying the ontology design recommendations developed by N. Guarino and C. Welty, that three of the four Group 1 entity types should be considered roles (relationships) rather than types. We then show how this analysis generalizes the solution to a previously identified puzzle in entity type assignment and is supported by John Searle's notion of a cascade of social facts established through collective intentionality -- which we take to be confirmation that this re-factoring results in a more accurate picture of the bibliographic domain. Finally we make some suggestions as to why it seemed that these entities were types rather than roles and note that in specific applications there may in fact be good practical reasons for models that treat types as roles.
