FYI, you can try to get a particular language by setting the accept-language header in citoid. It doesn't work a lot of the time because it doesn't work in Zotero, and of course it depends on if the resource accepts the accept-language header.

But, for instance, it works with twitter.com and 'de' so you would do:

$.ajax( {
	beforeSend: function (request) {
		request.setRequestHeader('Content-Type', 'application/json');
		request.setRequestHeader('Accept-Language', 'de'); // Use this header to request the resource in the particular language, i.e. 'en', 'de'

	},
	url: ' https://citoid.wikimedia.org/api'
	type: 'GET',
	data: { 
		search: encodeURIComponent('http://twitter.com'),
		format: 'mediawiki'
	},
	dataType: 'json',
	success: function ( citationArray ) {
		doSomething( citationArray );
	},
	error: function ( request, textStatus, errorThrown) {
		alert( 'Status:'  + textStatus +  'Error: ' + errorThrown );
	}
} );

This wasn't documented anywhere before but I just added some:

https://www.mediawiki.org/wiki/Citoid/API#In_a_JavaScript_userscript

code is currently at https://github.com/filbertkm/wikidata-citetool but could be moved to gerrit, differential, or wmde github.

It now sets title language based on user language, but not yet ability for user to change it except after saving the reference. (workign on making this nicer...)

It would be better, ideally, to have language provided by citoid in the backend.

some sources have html lang="en" (or whatever language) in the header. Maybe that could be used?

Also, there are language detection capabilities in elasticsearch and maybe available some other way.

For now, user language with ability to be able to change it is okay to keep things simple.

@Jan_Dittrich can you please add what you discussed with Katie here for the design? And mockups if there are any.

@Lydia_Pintscher: We did not discuss much, I only remarked that two buttons side by side that both insert a reference but resort to different methods are not ideal.
