At the end of 2022, I published a Blazegraph JNL file for Wikidata in a Google Cloud bucket for 1 month for folks to download and determine if it was useful.
Thanks to Arno from weblyzard, inflatador from the WMF search platform team, and Mark from the Internet Archive for the recent conversations around this topic.
You can now grab some new JNL files from a few days ago, hosted on either the Internet Archive or Cloudflare R2.
