Rights Metadata Recommendation
Vocabularies
| Prefix | URI |
|---|---|
| dc | http://purl.org/dc/elements/1.1/ |
| dcterms | http://purl.org/dc/terms/ |
| edm | http://www.europeana.eu/schemas/edm/ |
| pcdmrts | http://pcdm.org/rights# |
| premis | http://www.loc.gov/premis/rdf/v1# |
Minimal Rights Metadata
For maximum interoperability, we recommend two rights properties:
- edm:rights containing a URI designating the primary rights statement of the resource
- dcterms:rightsHolder containing a URI for the rights holder
| Property | Description | Values |
|---|---|---|
| edm:rights | Rights statement | URIs from Creative Commons, RightsStatements.org, other other vocabularies, minting new URIs as needed |
| dcterms:rightsHolder | Rights holder | URIs from common vocabularies |
Recommended Additional Properties
For a richer description of the rights status, we recommend the following properties to represent textual descriptions, links to explicit copyright information, and rights overrides (temporary licenses, embargoes, etc.):
| Property | Description | Values |
|---|---|---|
| dc:rights | Rights description | Free text description of rights, such as administrative contact information, a description of the specific license terms, or other rights-related restrictions. |
| marcrel:cpc | Copyright claimant (rights holder before rights expired) | URIs from common vocabularies (e.g., LCNAF, VIAF, etc.) |
| premis:hasCopyrightStatus | Copyright status | URIs from PREMIS CopyrightStatus |
| premis:hasCopyrightJurisdiction | Copyright jurisdiction | Country/jurisdiction codes from common vocabularies (e.g., ISO 3166) |
| pcdmrts:rightsOverride | Rights statement override (temporary rights statement that overrides edm:rights, such as a temporary embargo or license) | URIs from Creative Commons, RightsStatements.org, other other vocabularies, minting new URIs as needed |
| pcdmrts:rightsOverrideExpiration | Rights statement override expiration (date when status reverts to base edm:rights statement) | Date in a standardized format (e.g., W3C DTF profile of ISO 8601) |
