Came across this one:
[[Category:Football (soccer) terminology]]
The items in the category are not, as you might think, articles about soccer terms themselves. Rather, they are all concepts related to soccer, that have been put into this category for the (IMHO dubious) goal of producing an automatic "glossary" of soccer terms. It would seem to me that this category could be easily constructed by compiling all the entries of:
Football (soccer) laws Football (soccer) culture ...and probably lots of other categories that *should* exist.
I note that entries that are *only* in this category, and in no other soccer-related articles, are probably missing something. For example, [[Captain (football)]] really should be in some kind of "Category:Football (soccer) roles" or something.
Anyway, just something to bear in mind to extend my previous collection of category types. It could be just a type of thematic category, but this idea of building a glossary from a category is new to me.
Taxonomic/attributes (soccer laws) Thematic (soccer) Meta-attributes (stubs, 1911 etc) +Terminology (soccer terminology)
