For unknown reasons they have made it difficult to download the
machine readable version. You need a "free of charge licence
agreement" which is signed on paper, scanned and emailed to you if you
ask for a license. Not entirely sure about what they want to prevent
based on the license terms [1].

I have implemented DCAT over Atom on opengov.se and tried mapping some
keywords to Eurovoc (see an example at [2]). This feed is syndicated
to publicdata.eu (or was earlier at least).

I have a recent version of Eurovoc in SKOS [3] if you want to take a
look (but please read the text in [4] before clicking the link:-). If
I have understood correctly, each language version of a concept gets
its own URI. That should make it harder to do comparisons without
loading it all into a triple store.

Peter
