Re: wikipedia category hierarchy

Let me know when you put them together.
I'd like to add Wikipedia to the mKR

  Jens, thanks. dbpedia is a great resource. from the two categories files and the "articles categories" file, one can construct the whole structure of "what articles in what categories".

    One possibility is to go to and
    download the two data sets "Categories (Labels)" and "Categories
    (SKOS)". The categories are related via skos:broader and skow:narrower.
