Authority Responsible for an Identifier

Names the authority (such as CrossRef, Gen Bank, or PDB) that assigned the identifier or is responsible for the identifier


This attribute should be used to record the assigning authority for publication identifiers (<pub-id> such as DOIs (which might be assigned by, for example, “crossref” or “figshare”). The attribute can also be used to lessen the semanti overload on the @pub-id-type attribute, by recording the authority such as “GenBank” or “PDB” that assigned the identifier.
This attribute is used (as of this version) on two elements: <pub-id> and <ext-link>. The attribute makes more semantic sense for a publication identifier, but was assigned to <ext-link> to handle those rare cases where an external link, which is a link by definition, codes an identifier, such as a DOI.

With these Elements

Value Meaning
Text, numbers, or special characters The name of the organization assigning the identifier.
Restriction: @axis is an optional attribute; there is no default. The attribute is only used when the authority is known.
