Web app: add links to Ethnologue
Ethnologue by SIL has a nice new website with more info on particular languages, for example: https://www.ethnologue.com/language/rme/
With @kontur we agree this is better implemented as a reference in the actual Database and then perhaps used in the web app.
(Essentially, the webapp could show all references, literature reference as such, and web references as links)
Sorry, this has to be separate from sources as those indicate what was used to inform the data. Ethnologue and perhaps references to ISO (e.g. https://iso639-3.sil.org/code/aae) and Language Archives (e.g. http://www.language-archives.org/language/aae) are just an extra feature. Ethnologue has been cited only for a couple of entries, oddly.
Ah, I see; fair enough. Could be a same kind of generic list as sources, though; we can then show both on the webapp, where available. You get to name this ~~baby~~ attribute :P
