**Motivation**
- [[ https://en.wikipedia.org/wiki/en:Template:Information | w:en:Template:Information ]] has some rarely used extra parameters as compared to [[ https://commons.wikimedia.org/wiki/Template:Information | c:Template:Information ]] ("Location" and "Additional_information").
- Upon importing files to Commons with FileExporter/FileImporter, these parameters' content should not be lost, but concatenated into one parameter.
- See discussion at https://commons.wikimedia.org/wiki/Template_talk:Information#Additional_information
**Wish**
- Allow the substitution mechanism to concatenate rarely used parameters into the description field or an "other fields" parameter.
-- e.g. concatenate `|description=` and `|additional_information=` and `|location=`.
**Ideas**
- The substitution mechanism is already used to map from one template to another. Example: [[ https://commons.wikimedia.org/wiki/Template:Artwork/subst(information) | c:Template:Artwork/subst(information) ]] can be used to map from [[ https://commons.wikimedia.org/wiki/Template:Information | c:Template:Information ]] to [[ https://commons.wikimedia.org/wiki/Template:Artwork | c:Template:Artwork ]].
- Build a merge feature.
- Use a bot that cleans up the file description page after transfer and handles the additional parameters. (We're currently keep additional parameters in the wikitext, but they remain invisible because the Commons information template doesn't know them.)
**Notes**
If the fields are empty, delete them.
