Type of Journal Identifier
Type of publication identifier, such as a DOI or a publisher’s identifier.
Type of Identifier Best Practice: Best Practice is to reserve the @journal-id-type value for the specific type of the external identifier (such as a DOI) or for a generic type of identifier (such as a publisher’s identifier, an aggregator’s or archive’s identifier, the identifier assigned by an indexing or hosting service, or similar).
Authority Identifier Best Practice: The attribute @assigning-authority may name the organization or system that assigned the identifier or administers the identifier (such as Crossref, OCLC, LoC).
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 a journal identifier type is a DOI, many publishers use “doi” to keep all attribute values lower case, while others use “DOI” because that is the native language acronym..
Historical Note: Until JATS version 1.2d2 (2018), the @pub-id-type’s value conflated two meanings: the attribute could hold the type of identifier (such as a DOI or ISBN), or it could hold the name of the organization or system that defined or registered the identifier (such as Crossref). There was no way to state both that the identifier content of the element was a DOI and that the server was Figshare or Crossref. Although all the previous @pub-id-type values will continue to be accepted, for Best Practice, the @assigning-authority should name an organization and the @pub-id-type attribute should describe the identifier type.
Used on Elements: <journal-id>, <related-article>
|Text, numbers, or special characters||Word or phrase that identifies the organization or service who assigned the identifier (for example, “index” to indicate an abstracting or indexing service) or names the type of identifier (for example, “doi”).|
|Restriction||@journal-id-type is an optional attribute; there is no default.|
Although designed to accept any text as its value, the following are suggested journal identifier types for this attribute:
Identifier assigned to a work by an archive or other repository for articles
Identifier assigned to a work by a data aggregator
Digital Object Identifier for the entire journal, not just for the article (rare)
Identifier assigned to a work by an abstracting or indexing service
International Standard Serial Number for a journal (This value is generally used when referring to related articles.)
Identifier assigned to a work by PubMed, for example, “Mol Biol Cell”, “Nucleic Acids Res”, etc. This value is typically the journal abbreviation and may be the same as the abbreviated journal title <abbrev-journal-title>.
Identifier assigned to a work by PubMed Central, for example, a PubMed Central journal abbreviation such as “pnas”, “mbc”, “nar”, or “molcellb”, etc. This value is typically the journal abbreviation and may be the same as the abbreviated journal title <abbrev-journal-title>.
Identifier assigned to a work by the content publisher, for example, “MOLEC” or “MOLCEL”
... <journal-meta> <journal-id journal-id-type="pmc">pnas</journal-id> ... </journal-meta> ...
