Over recent days this list seems to have settled on something like: if you can get a "reasonable" representation it's content; if you can't it's description. For some definition of reasonableTaking 2 uris from dbpedia: http://dbpedia.org/resource/Fox_News_Channel is an organisation / corporation / tv channel. It's easyish to argue you can't get a reasonable response that isn't just a description http://dbpedia.org/resource/Fox_News_Channel_controversies is (in wikipedia terms) an overspill article. It could be a skos type concept I guess but it's more of a compound concept (a sentence). No matter what http evolves into, I can't think of a more reasonable response to that than a list of controversies involving fox news. What's the 303 doing in that case? It's made more confusing because the statements you get back from Fox_News_Channel_controversies are more or less identical to the statements you get back from Fox_News_Channel because the infoboxes on both wikipedia pages are more or less the same. So dbpedia says fox news controversies is an entity of type broadcaster and has a broadcastArea, a firstAirDate, a headquarter, an owningCompany, a pictureFormat etc Yours (in confusion) Michael
Michael,DBpedia is but one of many data sources accessible via the burgeoning Web of Linked Data. The relations in DBpedia are not always accurate per se., they typically provide a commencement point for additional finessing by subject matter experts. For instance, you can apply YAGO [1] context to DBpedia data en route to enhanced relations [2][3] that provide better descriptions for a given entity.
The emergence of the "Data Wiki" via projects such as OntoWiki [4] and Wikidata [5] will ultimately help everyone understand that Linked Data isn't a read-only affair where relations are implicitly canonical, and cast in stone :-)
