kwd-group-type Type or Kind of Keywords in the Group
The class or type of keyword, for example, “abbreviations” (for
keywords that contain an abbreviation and its expansion) or “author-provided”.
Usage/Remarks
If the keywords are from a controlled vocabulary, that vocabulary can be named in
the @vocab attribute.
The @kwd-group-type attribute is used in two different senses:
- The primary usage describes the class or type of keyword, for example, “abbreviations” for keywords that contain an abbreviation and its expansion, “hierarchical” for keywords that are grouped into a hierarchy, or “code” for keywords that contain a code and its text.
- Historically, this attribute also named the organizational source that established a particular group of keywords, although the attribute @assigning-authority is frequently more useful for that purpose. Currently, this attribute may be used to name the type of source, such as “author-provided” or “publisher”, if it is not needed to record keyword type.
When to Use @assigning-authority
Current best practice is to use the @assigning-authority to name the organizational source whenever that attribute is appropriate; for example,
Inspec, Crossref, Figshare, and other organizations should be tagged with @assigning-authority.
This @kwd-group-type attribute should have as values sources that are not appropriate assigning authorities,
such as
“author-provided”, “publisher”, and
“editorial”.
Historical Note: @vocab
In prior versions of this Tag Set, the @kwd-group-type attribute was used to hold a third type of information: the source of the keywords
in the group as the name of a generic (uncontrolled) vocabulary or of a controlled
vocabulary, taxonomy, ontology, database, thesaurus, etc. Since the @vocab attribute has been added to hold the name of the vocabulary, taxonomy, ontology,
etc., this information should no longer be put in the @kwd-group-type attribute.
