Use wikidata id's instead of wiki urls and create wiki urls from wikidata id

[PietrH]

Currently I'm adding wikipedia urls manually as I add an abbreviation, but I could just as easily add the wikidata id, and then the wiki page (English, then Dutch as they are available) can be fetched by a script.

• This script can rerun on every change, adding wikipedia articles as they get created
• We could fetch other information form wikidata as well, such as categories, that would open up a bunch of cool new features for later on
• We could select the language of the wikipedia articles to fetch (by preference, so always fetch x, unless not available, then fetch y)
