Change subject: Add custom wiki protocols for data access
......................................................................
Add custom wiki protocols for data access
* wikiapi:///?action=query&list=allpages
Call to api.php - ignores the path parameter, and only uses the query
* wikirest:///api/rest_v1/page/...
Call to RESTbase api - requires the path to start with "/api/"
* wikiraw:///MyPage/data
Get raw content of a wiki page, where the path is the title
of the page with an additional leading '/' which gets removed.
Uses mediawiki api, and extract the content after the request
*
wikirawupload://upload.wikimedia.org/wikipedia/commons/3/3e/Einstein_1921_by_F_Schmutzer_-_restoration.jpg
Get an image for the graph, e.g. from commons
This tag specifies any content from the uploads.* domain, without query params
