Authority Responsible for an Identifier
Names the authority that assigned or administers an identifier used in this document, for example, Crossref, GenBank, or PDB.
The attribute @assigning-authority names the organization or system that administers or is otherwise responsible for (has authority over) the identifier (such as Crossref, OCLC, GenBank, Ringgold, PDB, Figshare, ORCID, and others). The type of identifier for the element is typically recorded using a specific “-type” attribute such as @pub-id-type or @contrib-id-type.
Case in Attribute Values: Upper/lower/mixed case in attribute values for organizations and identifier types is likely to be variable and thus unreliable for search/discovery. If possible, JATS recommends a case-insensitive search for such values. For example, if the assigning authority is a ORCID, many publishers use “orcid” to keep all attribute values lower case, while others use “ORCID” because that is the native language acronym. Adding to this variability are identifiers that change over time. Expect to find the organization Crossref in values as “Crossref” (the currently preferred organization name), “CrossRef” (the previously preferred organization name), or “crossref” (for publishers who prefer all lower case for attributes).
Used on these Elements:
<ext-link>, <article-id>, <contrib-id>, <institution-id>, <issue-id>, <journal-id>, <object-id>, <pub-id>, <volume-id>
|Text, numbers, or special characters||The name of the organization assigning the identifier, such as “ORCID” or “ISNI”|
|Restriction||@assigning-authority is an optional attribute; there is no default. The attribute is only used when the authority is known.|
This attribute may take any text value, but it should name the authority, for example (not a complete list, just examplars):
