In order to make our HTML dump scraper data more usable, we had planned to publish the metadata on figshare, which is a data repository chosen by many wiki researchers. The process has already been worked out for an earlier edition of our data, which we unfortunately had to redact. See T341751: Publish dump scraper reports for the final text and more information.

Raw data itself is already published and can remain hosted on WMF infrastructure: https://analytics.wikimedia.org/published/datasets/one-off/html-dump-scraper-refs/
