compatiblewiththe4-foldpathforidentifyingarelatedentitywithanunstructureddescription,structureddescription,identifieroraccesspoint,andURI.
ThepaperassumesthatRDAwillgenerallycomplywiththeIFLAbibliographicmodels,consolidatedasFRBR-LRM(LibraryReferenceModel).
TerminologyTheprimaryterminologyusedinthisdocumentisfromtheRDAToolkit.TheequivalentterminologyfromtheRDARegistryisgiveninparentheses.
RelationshipsinRDARDAprovidesguidanceandinstructionsforcreatingdescriptionsandrelationshipsforthingsof
interesttousersoflibraryandculturalheritageservices.Theunderlyingconceptualmodels
(FRBR,FRAD,FRSAD)specifytheentities(RDFclasses)thatfocusoncommonattributesand
relationshipssharedbytheindividualthingsbeingdescribed;thingscanbetangible(for
example,personsormanufactureditems)orintangible(forexample,intellectualorcreative
works).Aunifiedconceptualmodel,FRBRLibraryReferenceModel(LRM),isinthefinalstagesforreviewandapprovalduring2016-2017.
EntitiesTheentitiesusedinRDAare:
Work(W),Expression(E),Manifestation(M),Item(I),Person(P),Family(F),CorporateBody(C).
Place(Pl)wasaddedtotheRDARegistrytoenabletheadditionofRDAToolkitelementsfor
placetosupporttheAugust2016releaseofRDAToolkit.ItisotherwiseundevelopedintheToolkit.
ElementsRDAprovideselements(RDFproperties)forspecificattributesandrelationships.Eachelement
hasaspecifiedentitytowhichitapplies(RDFdomain).Eachrelationshipelementalsospecifiestherelatedentitytowhichitapplies(RDFrange).
