On the one hand, it is perfectly fine to use it and, from a strict JSON-LD point of view it is also correct, because the `dc` prefix, ie, CURIE-s using `dc:` are fine according to our `@context` file. However, this is the only place I believe in the document when this mechanism is used; we usually use a pure term (and the corresponding mapping) in the `@context` file.\r\n\r\nI am perfectly file adding the term `description`, mapping to `dc:description` into the section on `Other properties` (3.3). But it is not a property that really fits into any of the subsections of that section, which is a bit awkward. Maybe a new subsection with some more common dc terms listed is the best of option (`subject`, `title`, ?). \r\n\r\nAlternatively, remove that term from the example, because it is, in fact, what we now call an extension. \r\n\r\nCc: @azaroth42 "}}
