Yes, indeed it would. The only Thing is that this would not be always easy to understand for the average user (who will use the WYSWIG-Editor) But generally the above Example would translate to: Somewhere on a London Xwiki page: [[UK>United Kingdom>predicate="capital_of"]] (correct ?) In OWL the Fact would be expressed via the triple: "London"-URL "capital of"-URL "UK"-URL All URL whould point to Concepts, while the Capital of Url would point to a Concept that is of the type "Object Property". http://en.wikipedia.org/wiki/Web_Ontology_Language The thing why this came to my mind was, that at some point you would like to ask the Wiki: "What is the capital of UK?". Or in corporate environments maybe: "Who is responsible for Product A?" Surely there has to be done a lot more, specifically in the query language. There are some Research Prototypes in Semantic Wikis, whilst the most appealing Java one seems to be IkeWiki for me now http://ikewiki.salzburgresearch.at/ Another even more structured system is freebase: http://www.freebase.com/view/en/xwiki Maybe it can give a short hinge what is possible and feasible. While I thought Nepomuk just used XWiki for a "CMS" it turns out that they also do research on the topic but I still cannot find any XWiki "branch" there.
