Testing WDQS Blazegraph data load performance
Toward the end of 2020 I spent some time blackbox testing data load times for WDQS and Blazegraph to try and find out which possible setting tweaks might make things faster. I didn’t come to any major conclusions as part of this effort but will write up the approach and data nonetheless incase it is…

It’s been roughly 1 month since WBStack appeared online, and it’s time for a quick review of what has been happening in the first month. If you don’t already know what WBStack is, then head to my introduction post. The number of users and wikis has slowly been increasing. In my last post I stated…
An introduction to WBStack

Creating a Dockerfile for the Wikibase Registry
