Yes, thank you, a lot of good feedback and a list of potential
candidates for dataset topic annotations. It seems that a mix of a big
broad taxonomy in combination with smaller national one has been used
in some cases.

When looking at use cases it is also important to make it easy to
classify datasets. Having a huge taxonomy to choose from may make it
difficult to use. Limiting the choice to top levels may make it
easier. If all we want to do is to facilitate discovery of similar
datasets that may be good enough.

On a side note there seems to be a lack of simple tools to create your
own material in SKOS. I have only found a handful that seems usable
for non-tech people (e.g. iQvoc).

Yes, NACE looks pretty simple to use and probably covers a lot of
topics. The relation could be <dataset> ---created from the
activity--- <nace code>.

An idea could be to use a subset of your national wikipedia data for
topics. Wikipedia is managed and  wikipedia articles in one language
are linked to their counterpart in other languages. They also have
categories which facilitate (some) hierarchy. Using wikipedia
(DBPedia) links it would be fairly easy to follow relations to other
datasets.
