One thing I will stress again in this discussion: UMBEL is basically two things: (1) a Subject Concept structure (space) and (2) a aggregation of Named Entities dictionaries (instances of classes). Please refer to the glossary to read the definition of each concept[1]. DBpedia is about instances of classes. DBpedia is linked (via sameAs since they come from the same data source: Wikipedia) to UMBEL named entities, and not UMBEL's subject concept structure (the SC structure helps instantiating these named entitites though). So, two things here: Wikipedia articles can be referred to many things. Two of these things are: this article is about this subject concept and this article is related to this other named entity. I think Jason is more thinking about linking Wikipedia articles with topical concepts; which refers to UMBEL subject concept. The linkage can be done using the umbel:isAbout predicate and any UMBEL subject concept. [1] http://umbel.org/sc_ne.html Thanks Take care, Fred
