Defining an atlas

[susannaanas]

An atlas could be defined in the parameter set with a category name of the atlas category in Wikimedia Commons. The template could devise a link to it and categorize the file into that category.

The sheet number could be used for automatic creation of an index map on the category page, perhaps.

What kind of exceptions are expected?

• Atlas is a web address
• Atlas is a Wikibook
  ...

How could we find out if parameter set has been used in map templates? I am keen to change it so that it creates a link to a category written in the field in plain text.

Old values need to be found out. I have made quite a lot of entries that are formatted as category links. They should be turned into plain text.

The problem with forcing the template to deal with this is that you either have to introduce yet another parameter or you outlaw any other use of the set parameter such as if the map is part of an atlas, but no/few other maps from this atlas are on commons (so parameter may contain plain text, wikipedia link, wikibooks link or a wikidata link).

What one could possibly do is to say that if set=<value> and <value> starts with "Category:" then display [[:<value>|<value>]] and add [[<value>|{{{sheet|{{BASEPAGENAME}}}}}]].

• the last bit just sets the sort key to the sheet value if present or defaults to the filename.
• aside: This would probably use Module:String#pos

It's (AFAIK) not possible to change the index map based on the templates in the individual maps.

Thanks for giving this a thought. I am more optimistic than I was about the feasibility!
