The binding between cfClass and cfClassSchemeId in the cfClassEntity may be dissolved with the next update of the CERIF model, in that the cfClassSchemeId will not continue to be part of the primary key and therefore not propagate to link tables. belonging to a scheme Person-Organisation Roles), e.g. belonging to a scheme Person-Publication Roles, e.g. (Academic Institution, Company, Society, Associationl. Some classification examples grouped by example schemes are e.g. cfOrganisationUnit_ResultProduct, cfEquipment_Funding, cfProject_ResultPatent, cfProject_Project, cfPerson_Classification, cfOrganisationUnit_ElectronicAddress, cfPerson_Service. The unique classification (cfClassId) + the unique classification scheme identifier (cfClassSchemeId) propagate to link tables: (e.g.
The classification scheme identifier (cfClassSchemeId) identifies a classification scheme system internally. belonging to a scheme Person-Organisation Roles), i.e. belonging to a scheme Person-Publication Roles, i.e.
Some classification examples grouped by example schemes are i.e. The classification unique identifier (cfClassId) propagates to link tables (i.e. A classification (uuid) is always assigned to at least one classification scheme (cfClassificationScheme or cfClassScheme) through the cfClassificationSchemeIdentifier (cfClassSchemeId) which is itself a uuid. In CERIF, the concept of Class is physically (cfClass) and logically (cfClassification) defined as an entity in an ERM, represented by attributes and through maintaining relationships with other entities: classes, multilingual descriptions, multilingual examples, multilingual definitions, multilingual terms, and all so-called CERIF link entities.Ī classification in the optimum case is uniquely identified through a uuid with the cfClassificationIdentifier (cfClassId) attribute (CERIF 1.3 provides a uuid for every specified term published at the euroCRIS website).
