Correction, it references a node shape that defines what facts you want to add to specific triples.
First, create a Node Shape e.g., Effectivity with properties effective start and end. Then, go to the property shape for the type of triples you want to annotate with effective dates (eg., works for property for a Person) and connect it to the node shape using reifiable by. I believe this is covered in the EDG users guide for ontologies, but I am not in front of my computer, so can’t provide a link.
