Dear DBpedia developers and users, the DBpedia URI for a Wikipedia page simply uses the page's title. If the page is renamed on Wikipedia, the DBpedia URI changes.
But cool URIs don't change. [1] What can we do? Here's a simple solution: Use the Wikipedia page ID. When a Wikipedia page is renamed, only its title changes, not its page ID. So to have more stable URIs, we should (additionally) generate URIs based on the page ID. (When a Wikipedia page is deleted and later re-created, the page ID changes, but that is much rarer than renaming.) There are a few questions: -- What should these page ID URIs look like? They should probably be in the http://dbpedia.org/resource/ namespace, but we must avoid name clashes. A Wikipedia title cannot start with an underscore, so we could use URIs like http://dbpedia.org/resource/_34234 . But maybe we would like to also use different IDs in the future. Maybe we should use something like http://dbpedia.org/resource/_id_34234 instead? Or maybe use a different namespace? How about http://dbpedia.org/id/34234 ? (Note that we can't use URIs like http://dbpedia.org/resource/id/34234 because "id/34234" is a valid Wikipedia title.) Or something quite different like http://dbpedia.org/resource/?id=34234 ... What do you think? -- How should we use the page ID URIs? For the near future, we should probably just generate sameAs triples that connect page ID URIs to title URIs. In the long run, should page ID URIs play a more prominent role? Should we extract whole datasets that use these URIs? Maybe we should first wait and see how many page titles (and page IDs) actually change from one release to the next to assess how stable or unstable the URIs are. By the way, although it's easy to get the page ID from the XML dump files, there seems to be no convenient way to get it through the web interface. You have to look at the HTML page source and look for "wgArticleId". For example, http://en.wikipedia.org/wiki/Berlin contains "wgArticleId":3354 somewhere in JavaScript code. One can use the page ID for URLs like http://en.wikipedia.org/?curid=3354 .
