Description

Hello

With the property P3896 :

SELECT  ?geo 
WHERE {
       wd:Q90 wdt:P3896 ?geo 
}

I found URIs on commons. For example :

http://commons.wikimedia.org/data/main/Data:Paris.map

But I can not read this file directly in a script because the CORS of commons.wikimedia.org is not open.
See the error :

Access to XMLHttpRequest at 'https://commons.wikimedia.org/data/main/Data:Paris.map' (redirected from 'http://commons.wikimedia.org/data/main/Data:Paris.map') from origin 'http://myserver' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Is it possible to resolve this access problem ?
Thanks

That endpoint is not returning valid json, only raw text.

The json endpoint as also used by Kartographer is:
https://commons.wikimedia.org/w/api.php?format=json&formatversion=2&action=jsondata&title=Paris.map

Or for usage by anonymous reusers:
https://commons.wikimedia.org/w/api.php?format=json&formatversion=2&action=jsondata&title=Paris.map&origin=*

closing as invalid as it seems to have been an issue with the way the api was used by the consumer.

@TheDJ Thanks for the response.

You know if it's possible to have only the geojson via the API ?

ie. only this part of JSONData :

{ "type": "FeatureCollection",
...
  }

Thanks
