This is a pretty good post, though the writing is pretty dense - if you are not deeply into metadata and application profiles then you might not be interested in this post. Basically, Dublin Core (as with any metadata specification) leaves open the question of which sort of descriptions ought to apply to which sort of entities in different contexts. An application profiles provides this determination. In this post, the development of application profiles as 'templates' or 'patterns' is discussed, what might be called 'description profiles'.
That said, work is progressing on a Education application profile via a wiki on the Dublin Core site. And Sarah Currier, in a post to the JISC mailing list, reports on the recent DC-Ed working session in Mexico. "Diane Hillmann mentioned at the Mexico session of the DC-Ed group that we should have some criteria for deciding on what vocabularies to consider: she is reported as saying they should be 'intelligently designed, maintained, and either have URIs or are willing to talk to someone about URI assignments.'" For my own part, it is not clear to me that vocabularies ought to be designed in advance of usage. But vocabularies that exist ought, perhaps, to be documented, providing that we understand that such an account is descriptive, and not normative.
