Hi everyone, 

We’re trying to get a clearer picture of what material we have on Wikimedia Commons so that our next batch upload doesn’t duplicate with material that is already on Commons. The category: Media from Open Beelden contains all the files and we would like to have all the metadata on Commons for that category (specifically the 'source' URL) to match against  our new content upload.

Does anyone know how to gather this using the Commons API? Basically, a call to the API with the “File:title” field that would return a JSON object with all the metadata is exactly what we need. Help would be much appreciated!

Best,

Jesse
