Hi all,
We managed to get skolemization working correctly for the WCQS beta
instance. As a reminder - this only affects WCQS, but there's a preview
available for WDQS as well [1] and we will be switching WDQS to skolemized
blank nodes in the near future.
Have a good day,
Zbyszko

Downtime is over - WCQS beta service has been restored
from the latest
(available on Monday) dump. Unfortunately, due to the issue with
skolemization for SDC dataset, using skolemized blank nodes change was
reverted - we will be working on figuring out what's the problem.
Have a good day,
Zbyszko

Hi all,
We are using this downtime to introduce blank node skolemization to WCQS
Beta[1]. This change is a prerequisite on our future work on real time
updates for that service.

Hi all,
Due to low disk space on the WCQS beta instance and possible data
corruption that might've happened because of it, we need to take down WCQS
beta and rebuild its journal - operation should take about 2 days -
starting now. I'm sorry for any inconvenience this may cause.
This is a recurring issue, but we have a permanent solution in the
pipeline on which we plan to start working on soon: [1].
