source-id-type Source Identifier Type
Type of source identifier (for example, a DOI, ISSN, ISBN, or publisher’s identifier) for a <related-object>.
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 source 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.
