    Paper presented at: IFLA WLIC 2015 - Cape Town, South Africa in Session 207 - Cataloguing. Vgl. den Kommentar von H. Wiesenmüller [Mail vom 25.06.2015]: "hier etwas höchst Spannendes - eine knappe Darstellung des konsolidierten FR-Modells, auf das wir schon so lange warten, und das im kommenden Jahr in das weltweite Begutachtungsverfahren gehen soll: http://library.ifla.org/1084/. Ich muss das Paper selbst auch erst in Ruhe lesen, sehe aber beim schnellen Durchblättern mit Freude bestätigt, dass die Gruppe-3-Entitäten aus FRBR tatsächlich abgeschafft werden. Die FRSAD-Entität "Thema" (die für alles stehen kann, was Thema eins Werks ist) wird umgetauft in "Res" (von lateinisch "res", Sache) und steht für "any entity in the universe of discourse". Die Entitäten der Gruppe 2 heißen jetzt zusammenfassend "Agent" und teilen sich auf in "Person" und "Group", wobei letzteres Körperschaften und Familien umfasst. Neu eingeführt wird "Time-span". Auf den ersten Blick scheint das jedenfalls alles ganz gut durchdacht zu sein."

    Abstract
    The models in the FRBR family include ways to document names or terms for all entities defined in the models, with identification as the ultimate aim, i.e., to distinguish entities by unique appellations and to use the most reliable appellations for entities in a given context. The intention in this paper is to explore the interrelationships between these different models with regards to their treatment of names, identifiers and other appellation entities. The specialisation/generalisation structure of the appellation-related entities and the relationships and properties of these entities will be discussed. The paper also tries to clarify the potential confusion of identity itself in this context - when are we talking about an entity via its name, about the name itself, about the name citation in a document and when about a name of name? In FRBR(er), titles for group 1, names for group 2 and terms for group 3 entities are merely defined as attributes of these entities. This serves the basic requirement of associating the appellation (label) with the entity, but does not allow introducing attributes of these appellations or relationships between and among them. FRAD, completed a decade later, defined as entities name, identifier, and controlled access point. Clearly making the distinction between a bibliographic entity and its name is a significant step taken in FRAD. This permits the separate treatment of relationships between the persons, families, and corporate bodies themselves and those relationships which instead operate between their names or between the controlled access points based on those names. In FRSAD, the most recent model, two entities are defined, Thema and Nomen. Again, the bibliographic entity is distinguished from the full range of its appellations. The FRBRoo model expanded on the treatment of appellations and identifiers in CRM by modeling the identifier assignment process. In FRBRoo, F12 Name was defined but identified with the existing CRM entity E41 Appellation. Current development is concentrating on integrating FRAD and FRSAD concepts into FRBRoo, and this is putting a focus on naming and appellations, causing new classes and properties to be defined, and requiring a re-evaluation of some of the decisions previously made in FRBRoo. As naming and appellations are such a significant feature of the FRBR family of conceptual models, this work is an important step in towards the consolidation of the models into a single coherent statement of the bibliographic universe.

    Abstract
    RDA, Resource Description and Access, is based on the foundation of the original entity-relationship statements of the conceptual models FRBR and FRAD. RDA not only uses the vocabulary of entities, attributes and relationships, as well as the user tasks, described in the models, these concepts also form an integral feature of its structure at both the macro level (the organisation of the sections and chapters of RDA reflects the models) and at a more detailed level within chapters. This paper reviews the degree of alignment of RDA with FRBR and FRAD, covering the areas of user tasks, entities, attributes, and relationships, and discusses the divergences of greater or lesser significance which exist. The FRBR user tasks are almost identical to the corresponding RDA tasks, but in RDA the wording and naming of tasks corresponding to the FRAD user tasks is reoriented towards the point of view of the end user. RDA adopts the bibliographic entities, but does not treat the FRAD entities name, identifier, or controlled access point as entities in their own right, even though the essence of the FRAD model of authority control is integrated into RDA. RDA's data elements can generally be traced back to attributes defined in either FRBR or FRAD, although at times at a greater level of granularity. The FRBR primary relationships are all included in RDA, but a direct link between work and manifestation is also defined in RDA with the work manifested relationship. RDA takes steps towards the harmonisation of the separate models, some obvious, such as adding the entity family to group 2 and using the FRAD definition of the entities person and corporate body, others less so, for instance in harmonising the different treatment of relationships among group 1 entities in the organisation of the relationship designators in appendix J. The ways in which RDA implements both FRBR and FRAD into a single content standard, as well as the ways in which RDA diverges from the models, may provide valuable insights for the consolidation of the FRBR family of conceptual models.
