Its anticipated use is to identify the RDF-Schema where a name is defined, which is not in conflict to the usage that we demand here. So one possibility is to extend the meaning of isDefinedBy in such a way, that for any resource the source URI is the range. There need not be a single source for an RDF-statement. Indeed can a certain model contain multiple source for the same statement. The discussion started with the following problem .
Semantic markup is inserted into the HTML-text.
However, if the text is copied this creates a maintenance nightmare. This is also true for any kind of resource, where the resource is in danger of a frequent change. So this problem has a wider range. Another example is e.g. the use of homepage-URIs as object identifier. This problem was also identified in posting 0106 .
