Good question. Short answer: No, DBpedia can't handle these templates,
and it's hard to change that.
It would be nice to do it in a generic way: design a system that
allows users of the mappings wiki to add rules how such templates
should be handled in a certain lanuage. Write Scala code that executes
these rules and parses the template definitions (e.g.
Modèle:Données/Toulouse/évolution_population) to extract the data and
store it in memory or in an temporary file. Then during the main
extraction, when you find a template call like {{Dernière population
commune de France}}, get the data from storage and generate the
appropriate triples.
A major effort. Related to
http://wiki.dbpedia.org/gsoc2013/ideas/CrowdsourceTestsAndRules , but
even bigger.
Maybe it would be easier to extend DBpedia such that the framework can
"execute" template definitions.
Maybe all that is a waste of time because the data will soon move to
Wikidata. We just don't know how soon: Three months? Three years?
Never?
