Alberto yr question is about a very generic example afaik, such schemas tend to be 'domain' specific, ie, you first need to identify want domain your categories/vocabulary falls under, then you can try to find if such a set exists already in the public domain By domain it is intended not only 'knowledge domain' (the specific topic you are trying to represent in the cats) but also 'system domain' (the platform/environment the knowledge domain lives in, referring more to the cateogirzation of a structure rather than its contents) https://libreplanet.org/wiki/Category:Top-level_categories https://wiki.roll20.net/Category:Top-level_categories //unfortunately, existing categorizasion schemas often mix the two, yak) see https://en.wikipedia.org/wiki/Category:Fundamental_categories There are few purely faceted classifications; the best known of these is the Colon Classification of S. R. Ranganathan, a general knowledge classification for libraries. https://en.wikipedia.org/wiki/Faceted_classification General top level categories are found in Deweys system, which is the nearest thing I can think of based on yr description https://en.wikipedia.org/wiki/List_of_Dewey_Decimal_classes pdm On 12/29/15, Alberto Nogales <anogales81@gmail.com> wrote: > Dear all, I am searching for vocabularies that let me classify terms, > something similar to an upper ontology.I am explaining that with a term > tree.
