What problem does this solve?


A single grant or program may have several different photography activities, such as workshops, wiki-expeditions and contests which fall under a variety of Commons categories.

What is the solution?

  • Hidden categories can be used on Commons to group files would not normally be categorized together due to the diversity of subjects depicted.
  • You can create a hidden category to group sub-categories that relate to individual programs that you are carrying out as part of a grant or project.
  • This will allow you to quickly locate all work created as part of your project. You can then use the GLAMorous tool to track and report file useage.
  • To hide a category, add the template Template:Hidden_category to the category page. This also places the page in Category:Hidden categories.

General considerations

  • Communities on larger Wikipedias may not be supportive of the use of hidden categories.
  • It is really helpful to include the year that a project was carried out as part of the name of the hidden category.
  • You should share the title of your hidden category in reports, so that WMF and the community can easily see the impact your work has across wiki projects.
  • You may use the hidden category temporarily for photo contedt judging. Grants:PEG/UG_TH/Wiki_Loves_X_in_Thailand_2015/Report#Learning_patterns
