WDQS Community meeting, 27 June 2022

There will be a new online community meeting (link) on Monday June 27, 2022 at 18:00 UTC.

The topic of the call will be the testing of the backend alternatives and the Blazegraph migration, and this will be also an opportunity to discuss the approach and the details, and to ask other questions about the Blazegraph alternatives work - such as how the Blazegraph-specific features and capabilities will (or will not) be supported. This will also be the last chance to talk to Andrea before her contract expires!
