description: ## Description The _DataCite Ontology_ (or simply DataCite) is an ontology written in OWL 2 DL to enable the metadata properties of the [DataCite Metadata Schema (version 4.7)](https://datacite-metadata-schema.readthedocs.io/en/4.7/) to be described in RDF. ![A diagram of the DataCite Ontology.](datacite.png) The main intent of the DataCite Ontology is to provide a flexible mechanism to define identifiers for bibliographic resources (e.g., papers and datasets) and related entities (e.g., authors). To this end, DataCite uses the object property `datacite:hasIdentifier`, which has as its object a member of the class `datacite:Identifier` or of one of its sub-classes (`datacite:ResourceIdentifier`, `datacite:AgentIdentifier` or `datacite:RightsIdentifier`). In turn, `datacite:AgentIdentifier` is further sub-classed by three additional classes, i.e., `datacite:PersonalIdentifier`, `datacite:OrganizationIdentifier`, and `datacite:FunderIdentifier`. The exact nature of the identifier is then defined using the second DataCite object property `datacite:usesIdentifierScheme`, which has as its object the class `datacite:IdentifierScheme` or one of its sub-classes: `datacite:ResourceIdentifierScheme`, `datacite:AgentIdentifierScheme` or `datacite:RightsIdentifierScheme`. `datacite:AgentIdentifierScheme` is further sub-classed by three additional classes, i.e., `datacite:PersonalIdentifierScheme`, `datacite:OrganizationIdentifierScheme`, and `datacite:FunderIdentifierScheme`. This provides a robust method for defining identifiers, since each specific identifier is defined as an individual member of its appropriate identifier scheme class. Of course, existing identifier schemes have been already defined within the ontology. For instance: * `datacite:doi` is an individual member of the class `datacite:ResourceIdentifierScheme` specifying a DataCite Digital Object Identifier (DOI); * `datacite:orcid` is an individual member of the class `datacite:PersonalIdentifierScheme` specifyi…
