Topic on Talk:Quarry

Is there any possibility to query the values of a specific parameter of a template? What I would like to have is something like a list of the values that are used for parameter "X" in template "Y".

No, this kind of thing is not stored (nor indexed) in the database. See also Topic:Xxndabd1sgspn08a.

There is no native MediaWiki data maintained to track this interesting semantic data. There once was a community maintained tool called Templatetiger that maintained a database of this type of information. Templatetiger's database was constructed by reading the monthly database dumps and parsing the wikitext content they contain. Technically the tool still exists, but the data it contains has not been updated in many years.

Thanks to both of you for your answers!
