specifying multilingual property values

Hi,

CSVW metadata spec says that one option how to specify multilingual natural
language properties is this:

"titles": {
  "en": "Project title",
  "fr": "Titre du projet"}

Is it OK, then, to use this method for CSV file metadata such as
"dc:description"?

The reason I am asking is because section 5.2 of the Primer specifies a
different, more verbose way to specify "dc:description".

Thanks,
Uldis
