I'd like to mirror just the category structure of the English Wikipedia, and
I'm wondering which of the dump files I need to start with.
I don't need the page content, just the page names, and only for the most
current revision. I need the categories and category members, and I'd like
to exclude hidden categories. I also need to distinguish redirects, because
I don't want to treat them as separate pages. As much as possible I'd like
to work with SQL files, but I can crunch through XML if necessary.
So which files do I need to download? I may also need some help in
understanding the schemas.
Thanks,
Robert
