@StephanKolassa It looks like I'm responding years after your question, but I'd say it is a good idea if the links are likely to still exist on the long run. Otherwise, as there are not a lot active users on this website (as you noticed :) ), it would increase the risk of having a persistent outdated wiki.

Not sure what other users think, if you're still interested, maybe you'll have a better shot at asking it on opendata.meta.stackexchange.com
