Object Identifier Type
Type of object identifier (for example, an XML ID, a string, the label of the object, a DOI) for a <related-object> element.
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 an object 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.
