After reading David's report,
I notice the the current CIF dictionaries 
don't seem to have any explicit publication specific keyword 
metadata definitions, such as 

      _publ_manuscript_keywords
or
      _publ_section_keywords

Probably just an oversight considering the wealth of 
other _publ_ and _journal_ definitions therein.
But it could be quite useful for propagating into
Dublin-core (RDF) subject metadata for HTML and XML 
renderings of CIF. It would probably need an official vocabulary of
terms and terminology to do it rigorously though.


mmCIF does have these definitions:

_entity_keywords.text
_struct_keywords.text
_struct_biol_keywords.text
_struct_site_keywords.text
