(This is a request from our [[https://de.wikipedia.org/wiki/Wikipedia_Diskussion:Technische_W%C3%BCnsche/Topw%C3%BCnsche/Verschieben_von_Dateien_nach_Commons#Weitere_Anpassungen_der_Dateibeschreibungsseite | project talk page on dewiki]].)
Local formats for file information should be translated into the format on Commons:
`|Date = DD.MM.YYYY` → `|Date = YYYY-MM-DD`
`|Anmerkungen`
- delete the field, if it's empty
- if it isn't empty, insert the content in the description field or use `|Other fields= {{Information field|Name=Remarks|Value={{de|Text aus Anmerkungen}} }}`
`|Description = Text` → `|Description = {{de|Text}}`or `|Description = {{de|1=Text}}`, if there's a `=` in the text
`== [[Wikipedia:Lizenzvorlagen für Bilder|Lizenz]]: ==` → `== {{int:license-header}} ==`
This is how it's done manually: https://commons.wikimedia.org/wiki/Special:Diff/334805191
