Raffle of the Day:

Raffle of the Day: Congratulations to yesterday's winner, Mike G.! (Since we've only had a few folks participating, we'll give away just one ticket now.) Today's raffle is for Veronika Heimsbakk's masterclass "Validating Semantic Knowledge Graphs Using SHACL" Have you ever struggled to validate your semantic knowledge graphs against a set of constraints? SHACL is a relatively new solution for this--by constraining RDF, SHACL allows you to validate kgs under a closed world assumption. Get an introduction to SHACL’s core constraints, learn what happens when the data conforms true vs. false, and how to put it all together for yourself in this interactive demonstration. You’ll gain hands-on experience identifying errors in validation reports and building shapes for ABoxes. This 2-hour class is ideal for information architectus, content creators, data modellers and other folks interested in high data integrity who have some knowledge of RDF. Thanks to Gregory Saumier-Finch for the suggestion!
