The Event Made Visible: Event-Based Modelling and Reifications in Turtle 1.2

The abstract:

For as long as RDF has existed, ontologists have faced a quiet embarrassment: the language that was supposed to let us say anything about anything had no clean way to say anything about a statement. You could assert that Alice knows Bob. You could not, without considerable ceremony, assert that this fact was recorded on a Tuesday by a particular system with a confidence of 0.87.

RDF 1.2, and specifically the April 2026 Working Draft of Turtle 1.2, changes that — not cosmetically, but structurally. This article is about what that change actually means for the way you model, and why it pushes the design centre of gravity away from nouns and towards events.
