/ Anahi Olives/UPC <Anahi.Olives@upc.es> was heard to say:
| Which is difference between "Keyword" and "Subject"? I want to allow to
| include in a document keywords that describe the content of the document,
| and in that way, search documents more efficiently. I saw that "Keyword" do
| this, but does "Subject" too? Which one should I use?

They serve essentially the same purpose. Subjectset terms should be
drawn from a controlled vocabulary; keywordset terms are free-form.
See the reference pages:

  http://docbook.org/tdg/en/html/keywordset.html
  http://docbook.org/tdg/en/html/subjectset.html

                                        Be seeing you,
                                          norm
