person-group-type Type of People in the Person Group

Role of the person(s) being named in the <person-group> element (for example, author, editor, curator).

Usage/Remarks

The @person-group-type attribute was designed to name the role of the contributor inside a <person-group>. This tag set has a fixed list of types such as (“allauthors”, “assignee”, “compiler”, “curator”, “director”, etc.).

Semantic Roles Best Practice

When a contributor role is described by a controlled vocabulary, such as the ANSI/NISO Contributor Role Taxonomy (CRediT), best practice is not to use the @person-group-type attribute to name the formal contributor role. (The attribute may still be useful for informal groupings such as “editors”.)
Best practice is to use the <role> element inside <person-group> to indicate that all members of the group perform the same function. The vocabulary attributes on <role> should then point directly to the appropriate CRediT term, allowing the content of the <role> element to take any useful display value, while still preserving the CRediT semantics.
The major advantages of using <role> instead of @person-group-type are:
  • the ability to tie the content of the role to a formal vocabulary using the four JATS vocabulary attributes, and
  • the ability for a contributor to play more than one role in the creation of an article.
Of course, even when not using a controlled vocabulary, it is always possible to substitute the element <role> for the attribute @person-group-type.

Person Group Type Not on the List

When a JATS tagger needs to record a value that is not a named value on the list, they should use the value “custom”. This tells a JATS processor that this @person-group-type is not one of the known types. The attribute @custom-type should then be used to record the type of person group. 
<person-group person-group-type="custom" custom-type="statisticians">
For any <person-group> with a @person-group-type attribute that takes the value “custom”, then the @custom-type attribute should be used and should have a value. Schematron or similar can be used to enforce this and, if desired, to constrain the @custom-type values.
OPTIONAL on element: <person-group>
