Open Access license information

Capture Open Access license information in a license element

permissions/license[@license-type and @xlink:href]

Content with a Creative Commons Open Access license must include a license element with a license-type attribute whose value corresponds to the license type.

License Type	license-type Attribute value
CC-BY	cc-by
CC-BY-IGO	cc-by-igo
CC-BY-NC	cc-by-nc
CC-BY-NC-ND	cc-by-nc-nd
CC-BY-NC-SA	cc-by-nc-sa
CC-BY-ND	cc-by-nd
CC-BY-SA	cc-by-sa

Give each license element an xlink:href attribute with the value of the URL of the applicable Creative Commons licence.

The xlink:href must be updated to match the applicable Creative Commons license in the copyright line. The URL must start with https.

Erratum, corrigendum or retraction notices where the related article has a creative commons open access license must also include the same license tagged in license-type

Include the text of the license inside a license-p element.

Find the correct Open Access license text in the Reference Library, in the Copyright Lines and Information document.
