On this page: http://ontoworld.org/wiki/Relation:Instance_of it says that Relation:Instance_of and Relation:Subclass_of are deprecated and you are only allowed to use the category system. Maybe it was decided that average users cannot tell the difference between "instance of" and "subclass of", and so we are stuck with only "category". Is that why the decision was made to try to get by with the ambiguous use of "category"?
For example, here is the Wikipedia category Hindi-language_films: http://en.wikipedia.org/wiki/Category:Hindi-language_films Note that this category belongs to 3 other categories in 3 very different senses: 1. Subclass of: "Indian_films". A specific film that is a Hindi language film is also an Indian film, so the category Hindi-language_films is a subclass of Indian_films. 2. Instance of: "Films_by_language". A specific film that is a Hindi language film is *not* a film by language. Rather, it is the category Hindi-language_films that is an instance of the higher-level category of Films_by_language, along with other categories like Tamil-language_films. 3. Somehow related to: "Bollywood". The category Hindi-language_films has something to do with Bollywood, but the relationship is not specified. However, isn't that the whole point of the Semantic Web, to make the relationships explicit? But the category system is as generic as an untagged link in Web 1.0 that we are trying to fix with Web 3.0. Is there a web page or statement about how the Semantic Mediawiki will handle these 3 different types of relations, if the more meaningful relations are deprecated and we are only allowed to use the category system? Is it a totally closed issue?
