Hi Donald,

I have deleted wikibases on wikibase.cloud (because I couldn't create a seventh one, due to the limit of six), and then could create new ones; so, it seems clear that deleted wikibases do not count for the limit.

I have not tried to re-use the same name. I think in wbstack there was a warning, saying that names cannot be re-used. That makes sense, since the old entity URI should not describe something else in the new wikibase. It should be like when you delete an entity: That entity ID will be unavailable, in order not to create conflicts e.g. with external datasets pointing to that URI. But I am not sure what policy wikibase.cloud follows regarding re-using namespaces of deleted wikibase instances for new instances.

Best

Hi Wikibase Community,

I recently asked the following in the wikibase.cloud telegram group:

Is there an easy way of resetting an existing instance to zero -
the same effect that we got when we threw away persistent volumes
in a docker-managed instance. For sandbox use cases, it's really
helpful to be able to start from scratch again easily. I suppose
the next best thing would be to delete an instance and make a new one.

Greenreaper commented:

I'm not aware of a way to do this but as you say making a new one
should be fine, my only concern is whether deleted ones count for
the current limit of six wikibases. Also not sure if the deleted
names are reserved, they may be.

Could anyone give a definitive answer to those wb.c questions? Do deleted wb.c instances count against quota? Could one create a new instance with the same name as a deleted one?

And from the point of view of pure wikibase (leaving out the .cloud), is there a nice way of resetting an instance to empty?

Thanks,

Max (Donald) Ziff
