like many link relations, 'about' and 'describes' are fuzzy in their 
scope and definition. 'describes' in particular is probably so generic 
that you can use it for pretty much anything. i would find it surprising 
if there was any possible succinct explanation of the difference.

personally, i think that link relations almost always depend on the 
context they're used in. in one API you might find something exposed as 
'about' links, which in a different API is exposed as 'describes' links. 
you have to know the context (the APIs) to understand what they expose, 
and how they do it.

cheers,

dret.

The context I'm thinking of is landing pages, e.g. DOI and Datacite. So Her=
