Usage/Remarks

This attributes holds the type of keyword for many kinds of keyword groups, for example, “hierarchical” for keywords that are grouped into a hierarchy, “abbreviations” for keywords that contain an abbreviation and its expansion, or “code” for keywords that contain a code and its text.

Source of the keyword

In current BITS, the @vocab attribute should be used to hold the name of a controlled or generic (uncontrolled) vocabulary, taxonomy, ontology, database, thesaurus, etc. that is the source of the keywords in the group, for example, “CRediT”, “DCC”, “structural engineering”, “ISO-463”, or “ICD9-codes”, etc.
In prior versions of this Tag Set, the @kwd-group-type attribute (which is still semantically overloaded) was used to hold keyword sources.

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”.
