I hope this doesn't change too. Felt I had to use it to link a humongous wikidata SPARQL query in a (software) research paper recently.
I hope you added the entire link in an appendix, otherwise it’s not Google’s fault for ruining your paper.
The query itself is available in a screenshot. Also a pretty periferal part of the paper.
Looked/thought hard about options but did not come up with better at the time.
But wanted to highlight how important it is for parties starting such services to have a plan for longevity. Hopefully Goog will keep old links going for a long time.
