Data templates
Language-independent information should be stored in a specific template (a “data template“), to be referred to by each localized template (e.g. English, French, etc). This avoids duplicating data in different pages and improves maintainability and stability. Such templates should use {{Data template used}}, which will categorize them in Category:Translating templates.
Data templates for parts
For instance, Rockomax 48-7S (English), Rockomax 48-7S/pl (Polish) and Rockomax 48-7S/ja (Japanese) all use the same raw data stored in the data template Rockomax 48-7S/Box to draw the infobox on the right. To do so, they simply include {{:Rockomax 48-7S/Box}}
. Mind the colon (":").
Rockomax 48-7S/Box itself includes {{Infobox/Part}}, which defines how the infobox is to be drawn and how to translate it.
Data template for celestial bodies
The infobox for celestial body works a little different. Instead of having the complete infobox in an seperate article like Rockomax 48-7S/Box it only has the values stored in a page like Kerbin/Param. The template then automatically gets the value from that page so in a page like Kerbin only {{Infobox/Body}} is required.
