Introduction

The DataCite Ontology is an ontology written in OWL 2 DL to enable the metadata properties of the [DataCite Metadata Kernel Specification version 3.1](https://www.datacite.org/sites/default/files/document/DataCite-MetadataSchema_V31_Final_8-24-2015_0.pdf) to be described in RDF. This version of the DataCite Ontology has been completely revised and significantly expanded to permit accurate mapping of this new version of the DataCite Metadata Kernel Specification to RDF.

Classes

agent identifierc back to ToC or Class ToC

IRI: http://purl.org/spar/datacite/AgentIdentifier

alternate resource identifierc back to ToC or Class ToC

IRI: http://purl.org/spar/datacite/AlternateResourceIdentifier

An identifier other than a DOI that is used as an alternative identifier to uniquely identifies the primary resource that is the subject of the DataCite metadata record, belonging to a particular scheme such as ISBN specified by an individual that is a member of the class datacite:ResourceIdentifierScheme.

description typec back to ToC or Class ToC

IRI: http://purl.org/spar/datacite/DescriptionType

This class permits classification of the type of description given to a resource described by the DataCite Metadata schema. Individual members of the class conform to the five values allowed in the DataCite controlled list, namely: * abstract; * methods; * series-information; * table-of-content; * other.

funder identifier schemec back to ToC or Class ToC

metadata schemec back to ToC or Class ToC

IRI: http://purl.org/spar/datacite/MetadataScheme

The class that describe metadata schemes used for creating a metadata document referring to a certain resource. Neither a class for metadata documents nor a property linking a resource to its metadata document are not explicitly defined in this ontology. However, we recommend to use the class fabio:MetadataDocument (from http://purl.org/spar/fabio) and cito:citesAsMetadataDocument (from http://purl.org/spar/cito) for providing such descriptions. An example of use of such entities is shown as follows: :my-resource cito:citesAsMetadataDocument :my-resource-metadata . :my-resource-metadata a fabio:MetadataDocument ; datacite:usesMetadataScheme datacite:spar . In addition, if needed, it is possible to use the dataproperty fabio:hasURL (not included in this ontology as well) for defining the actual URL of a certain metadata scheme.
