dc/dcterms: subject

[tombaker]

EDITED

• dc11:subject (through 2019)

  Comment reads: "Typically, the subject will be
  represented using keywords, key phrases, or
  classification codes. Recommended best practice is to
  use a controlled vocabulary."

• dcterms:subject (ISO 15836-2 / DCMIMT 2020)

  Comment reads: "Recommended practice is to refer to
  the subject with a URI. If this is not possible or
  feasible, a literal value that identifies the subject
  may be provided. Both should preferably refer to a
  subject in a controlled vocabulary."
