Ok, but… Suppose someone sends me data ‘height “4 m” ‘ for a bridge
And height is not in my shacl in any way for the bridge shape No sh:closed will give no validation error sh:closed will give validation error (feels like a kind of implicit maxCount=0 for all non-path declared properties) Right? And then my question was/is: what is good practise: being strict (like in the traditional languages of the past: data for non-declared properties give error) or be a bit more flexible and allow data for non-mentioned properties? The latter feels ‘a bit more OWA’ wrt cardinalities….(I know owa is related to assuming false when unknown…but maybe not the right word if people give you more than expected 😊) Dr. ir. H.M.

Under OWA, there is no issue. It does not mean that you have to list all possible properties. If you specify sh:closed = true, then you do have to list all possible properties or put them into sh:ignore. Or if you have something else to say about property values.
