assigning-authority Authority Responsible for an Identifier

Names the authority that assigned or administers an identifier used in this document, for example, Crossref, GenBank, or PDB.

Usage/Remarks

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 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).
