List of classes and properties in the BFFI datamodel which are not in the BIBFRAME datamodel

We have added several classes and properties to our data model. Almost all of these are directly based on RDA with a couple of additions that have to do with the Finnish cataloguing conventions.

Added entities not listed here

• We do not list here the classes and properties that have to do with the RDA WEMI model (e.g. bf:Audio was split into to bffi:AudioWork and bffi:AudioExpression).
• Similarly, we don't list here the added properties that relate to representative expressions (e.g. bffi:intendedAudienceOfRepresentativeExpression). - See a separate discussion on RDA representative expressions. Additional information:
  • RDA Toolkit: Maxwell Representative Expression in Authority Records Sept 2022.pdf
  • LC-PCC Metadata Guidance Document: [Element] of representative expression

List of added entities

We added a few classes for aggregates and collections

• bffi:AggregatingWork bffi:AggregatingExpression bffi:CollectionManifestation bffi:CollectionItem

We added several classes to provide lists of controlled values for certain properties taken from the RDA model.

• bffi:CollectionAccrualMethod bffi:CollectionAccrualPolicy bffi:ExtensionPlan bffi:RecordingSource bffi:ScaleDesignation bffi:SourceConsulted

We added classes to provide controlled lists of values for cataloguing in general.

• bffi:Degree bffi:TitleNote bffi:TitleSource

We added a class needed for cataloguing choreographic medium to separate these from bffi:MusicMedium

• bffi:ChoreographicMedium

We added several properties corresponding to the classes added.

• bffi:collectionAccrualMethod bffi:collectionAccrualPolicy bffi:extensionPlan bffi:recordingSource bffi:scaleDesignation bffi:titleNote bffi:titleSource

We added properties for cataloguing cartographic material in accordance with RDA.

• bffi:additionalScaleInformation bffi:horizontalScale bffi:verticalScale

We added properties related to collections in accordance with RDA.
