Subject An individual entitiy that is described on a wiki page. Can be basically anything. Wikipage A page in a wiki Connects a swivt:Subject (URI) with the according swivt:Wikipage (URL). page has type The wiki-specified type of a property. base property The base property of a property is an abstract property that does not specify sufficiently certain values so that the property value can be properly understood. It connects two properties with each other, for example lenght_(meters) has the base property lenght and the modifier meters. modifier Connects a property with a string that instantiates the meaning of the abstract base property connected to the property. For example, the triple a length 3 would have no meaning, since it is unclear in what unit 3 has to be understood. Here we introduce a new property lenght_(m) with the base property lenght and the modifier m, so that we know the 3 is measured in m. Container An intermediate entity that allows to create n-ary values for a specific attribute. An NAry is naught but an intermediate node. parameter 1 Connects an NAry to parameter 1 of the NAry. parameter 1 Connects an NAry to parameter 1 of the NAry.
