Hi Chris,

I think many of us may be having trouble answering this because it's not quite clear what you're trying to do. Can you be more concrete about what categories (or what category scheme) you have in mind?

Wikipedia doesn't have a single, overarching hierarchy of categories. A page may be associated with any number of categories (including zero). Some of these categories may be subcategories of other categories. Editors may freely create and remove categories, and add and remove page associations with these categories.

The REST API currently doesn't expose any category information, but you can obtain category information through follow up requests to the Action API (https://en.wikipedia.org/w/api.php). For example:

To get all categories associated with the page "Marfa, Texas" on English Wikipedia:

https://en.wikipedia.org/w/api.php?action=query&prop=categories&titles=Marfa,_Texas&cllimit=500

To get all pages associated with the category "Category:Cities in Presidio County, Texas":

https://en.wikipedia.org/w/api.php?action=query&list=categorymembers&cmtitle=Category:Cities_in_Presidio_County,_Texas

Best,

Michael

Hello,
We’re a small app development company that has integrated Wikipedia content into a geo-locating iOS app. The app is working well and the Wiki content is displaying correctly. However, we’d like to categorise the Wikipedia content into three categories rather than just one.
Is there a way to filter and categorise Wikipedia content that is accessed through the REST API? We only use content that is geo-coded (ie has latitude and longitude) information associated with each article.
How should we go about configuring our API integration so that we can split Wikipedia content according to its top-level categories? Is there a way to do this?

Many thanks for your assistance with this request.

Regards,
Chris Smyth
