Re: [dxwg] suggestion to add a property thumbnail to dataset (#1357)

Some more additional thoughts after investigating this proposal: it does not seem necessary that the distribution it is referring to should obey the same rules as a dataset distribution. For a thumbnail distribution: 

- downloadURL, mediatype are probably required for technical reasons to show on a portal. 
- title & description are needed in case for supporting WCAG 

In general the accessibility and usage requirements of samples is much lower than those of real dataset distributions (if I can call them so). I would expect that DCAT profiles therefore introduce different guidelines for samples.

I would add that in the usage note on sample. As it seems natural for profile builders to draw an arrow to dcat:distribution for a sample, but then one will bump into the case that the profile insists on a license for a (dataset) distribution while for a sample/thumbnail this  is not required. Indeed a lot of the metadata requirements for dataset distributions are for samples specifiable, but never used. (I have to see the first portal that would dynamically check the license before rendering a thumbnail) For that reason I believe dedicated subclasses of Distribution could appear bound to a particular usage context:, for instance thumbnails.
