Cannot add categories to Commons Datasets
Closed, DuplicatePublic


When adding a category to a Commons Dataset (for instance this one), the following error message appears:

You cannot edit this revision because its content model is Tabular.JsonConfig, which differs from the current content model of the page wikitext.

Without categorization it becomes hard to organize datasets in the existing model in Commons.

@Micru please explain what do you mean by "adding a category".

Did you try to add manually [[Category:Foo]] (or through HotCats) at the bottom of the page?

If so, this is a probably a good message: the page expects a JSON format, not wikitext.

Thanks @Micru! This is actually several different issues:

  • The category picker UI shown at the bottom of the page does not handle non-wiki pages properly (it attempts to change the page from JSON into Wikimarkup
  • There is no structured way to add categories
  • "sources", the only wiki markup field in the json, hides the [[category:...]] text as it is suppose to, but does not record it in the database. See example.

As a temporary workaround, we could add categories to the talk pages? I know its not perfect, and hopefully we will have this fixed right after New Years' holidays.

@Micru no, the Data: namespace is special - it only allows special page types. There is no subpages there, or any wiki pages for that matter, only the .map and .tab pages. Hence the talk page is the closest one at the moment :(

The implementation of T155290 will solve this problem as well, so I'm merging these tasks together.
