The notions of dataset and distributions are key to DCAT. They match
similar ideas in other domains, notably the library world's FRBR
vocabulary that distinguishes between a Work, such as 'Beethoven's 5th'
and its Expression, such as a particular recording or performance.

Licences are attached to DCAT Distributions, not Datasets, because it's
possible that different distributions of the same data will be released
under different licences. For example, a PDF might be available under an
open licence, whilst a proprietary format might be under a more
restrictive licence.

It may be worth noting that dcat:Distribution and dcat:Dataset are not
disjoint, so if there's just one file that is the dataset then it can be
both, but we probably shouldn't promote this too heavily as it might
lead people to lose the distinction between the two classes.

So, bottom line, yes, I think we should distinguish between datasets and
distributions in our work.

Phil.
