Topic on Talk:Content translation/Templates

I'm currently working on Extension:FileImporter, and interested in how the TemplateData approach here might be used to help us convert templates and parameters when moving files to commonswiki. Two questions jump out so far,

• How are templates mapped to one another when the names are different? Are you using Wikidata, e.g. [[d:Q5611625]]?
• What has your experience been with the "aliases" field for mapping parameters? Has there been discussion about increasing the amount of structure? Are many exceptions encountered?

I have basically the same question.

e.g.: en:Template:Distinguish should be translated to de:Vorlage:Dieser Artikel {{Dieser Artikel|1=beschreibt nicht %1.}}

Where to put these sort of mappings?

Not an official answer, but I found some interesting documentation about the topic: Content translation/Templates. I think that templates are mapped through Wikidata, but parameter mapping is a complex and heuristic feature. Template parameter mappings are done with help from a machine learning model which does automatic translation of parameter names, estimates how likely it is that parameters are aligned, for example see https://phabricator.wikimedia.org/T221211 .

To create a mapping for your case, I went to en:Template:Distinguish, clicked "Wikidata item" to find wikidata:Q6458914. I tried to add a site link to de:Vorlage:Dieser Artikel, but ran into an issue: this template is already connected to item wikidata:Q5766677. It seems like a fundamental problem that templates can't have a many-to-one relationship because each wikidata item is intended to be unique, and site links aren't really designed for something like template mapping.

Sorry that my answer just leads to a new technical obstacle!

Nevertheless thanks for your endeavour.

Wikidata not handling many-to-one relations is even a problem for articles, because sometimes one English article has two German counterparts or vice versa.
