Hi Julien, thanks for the heads-up!

I'm not 100% sure, and we should look into this, but I think that Lua is only used in template definitions, not in template calls or other places in content pages. DBpedia does not parse template definitions, only content pages. The content pages probably will only change in minor ways, if at all. For example, {{Foo}} might change to {{#invoke:Foo}}.

I've seen similar structures on Wikipedia de [1] and I think also on pl or cs: the actual data is not in the content pages, but in some template, and is rendered on the content page by rather complex mechanisms. To deal with this, DBpedia could try to expand templates, or maybe just certain templates (we don't want all the HTML stuff). Great generality, but may cause perfomance and other problems. In the worst case, mapping-based extraction could become as slow as abstract extraction. Or we could let people add rules on the mappings wiki about which templates contain data and how the data should be attached to certain DBpedia resources. Of course, determining syntax and semantics for such rules wouldn't be trivial... ...but if we get there, we could implement the data extraction as a preprocessing step: in a first extraction phase, go through the Wikipedia dump, collect and store stuff from these 'data templates', and during the main extraction, pull the data from the store where needed and generate triples. Informally, we already have such a preprocessing phase for the redirects. It would make sense to "formalize" it and also use it for other info, e.g. disambiguation pages, inter-language links, resource types, etc. Cheers, JC [1] For example, http://de.wikipedia.org/wiki/Hannover contains {{Infobox Gemeinde in Deutschland ... | Gemeindeschlüssel = 03241001 ... }} ("Gemeinde in Deutschland" means "community in Germany", "Gemeindeschlüssel" means "community key".) The actual data is in pages like http://de.wikipedia.org/wiki/Vorlage:Metadaten_Einwohnerzahl_DE-NI > > I hope that I was enough clear, otherwise don't hesitate to ask me some > informations in more about these problems. > > Thanks for your lights. > > Best regards. > > Julien Plu. > > ------------------------------------------------------------------------------ > Minimize network downtime and maximize team effectiveness. > Reduce network management and security costs.Learn how to hire > the most talented Cisco Certified professionals.
