14. Resource Identifier (M)¶
datacite:identifier
14.2. Definition and Usage Instruction¶
The Identifier is a unique string that identifies a resource.
Usage Instruction
Recommended best practice is to identify the resource by means of a string or number conforming to a formal identification system. Example formal identification systems include the Uniform Resource Identifier (URI), the Uniform Resource Locator (URL), the Digital Object Identifier (DOI), and the URN:NBN
. Also this can be a direct URL, or a redirection URL, like PURL, HANDLE or other international resolution mechanisms.
The ideal use of this element is to use a direct link or a link to a jump-off page (persistent URL) from identifier
in the metadata record to the digital resource or a jump-off page.
Smart practice:
- use a stable, sustainable URL
Remarks
- adapted from DataCite MetadataKernel v4.1
Do Not Confuse With
- Alternate Identifier (R) (Use
datacite:alternativeIdentifier
to list other identifiers than the primary identifier applied to the same resource.) - Related Identifier (R) (Use
datacite:relatedIdentifier
to refer to related resources.) - File Location (MA) (Use
oaire:file
to point to the resource being desccribed by this metadata, e.g. the fulltext file.) - Source (R) (Use
dc:source
for bibliographic citation of the originating resource.)
14.2.1. Property identifier (M, 1)¶
Use the identifier link as value.
14.2.2. Attribute identifierType (M)¶
The type of the Identifier (occurrences: 1).
Allowed values, examples, other constraints
Controlled list values
- ARK
- DOI
- Handle
- IGSN
- PURL

Note
Unlike DataCite, OpenAIRE allows for DOIs and other types of identifiers.
14.3. FAIR enabled¶
Indicator | Priority | Description |
---|---|---|
RDA-F1-01M | essential | Metadata is identified by a persistent identifier |
RDA-F1-02M | essential | Metadata is identified by a global unique id |
RDA-A1.1-01D | important | Data is accessible through a free access protocol |
14.4. Example¶
In this example the handle redirects to the jump-off page. A jump-off page is a good way to refer to. The end-user has the opportunity to see more information about the object(s) he has found, see the context and enjoy the other services a local repository has to offer:
1 | <datacite:identifier identifierType="Handle">http://hdl.handle.net/1234/5628</datacite:identifier>
