Hello,
In 2018, the Wikibase Registry was started to create a Wikibase of Wikibases, linking the
different Wikibases in existence together in pursuit of a greater “Wikibase
federation."
The Registry was started as a standalone Wikibase on Wikimedia Cloud Services, and it had
fallen behind in content and technical maintenance. Lack of effective anti-spam measures
meant strict editing restrictions, which did not help.
Since then, a new Wikibase Cloud supported by Wikimedia Germany was created. Since this
service will continue to receive software updates and generally has more features, I have
migrated the contents of Wikibase Registry to a new wiki at a new URL:
<https://wikibase.world>. I encourage you to sign up and, if you have a Wikibase
accessible over the open internet, to add an entry for it.
Links to Wikibase Registry will continue to work indefinitely. As Wikibase World is a new
wiki with new item and property identifiers, I have created a static mapping between old
and new at <https://wikibase-registry.wmflabs.org/mapping>. This mapping forms the
basis of the redirect service; try visiting
<https://wikibase-registry.wmflabs.org/wiki/Item:Q5> or
<https://wikibase-registry.wmflabs.org/entity/P19> to see it in action.
The old Wikibase Registry is available as a read-only archive at
<https://wikibase-registry-archive.wmcloud.org/wiki/Main_Page>. It says on the site
that it is going offline today, July 1, but so long as no vulnerabilities in the old
version of MediaWiki being used are being exploited in its read-only state I can keep it
online indefinitely[1]. However, once it goes offline, you should assume it will not
return. However, be assured that final XML and RDF dumps were created and uploaded to the
Internet Archive: <https://archive.org/details/wikibase-registry-final-2023-06-16>.
Finally, I have created a companion Discourse to go along, at
<https://forum.wikibase.world>. This Discourse can also be used for other Wikibases
that wish to have a place for discussion without setting up their own forum.
Thank you,
James Hare

running the VM reaches end-of-life, at which point I will be forced to shut it down.
