Hi, I have a need to model this constraint in SHACL:
*An Entertainment Holding Company must own one and only one instance of EACH of the following classes: Movie Company, Racing Company, and Streaming Company in order to be a valid instance of Entertainment Holding Company.* This is an example of a valid instance: [image: image.png] Any more or less than 3 st:owns triples or more or less than 1 instance of the three classes listed above should be a violation. I have tried numerous ways to model this behavior without success. SHACL seems to iterate through each object of the st:owns property where I'm making a statement about the set of st:owns objects. I encounter this type of problem frequently so I'm hoping there is a pattern I can apply as a generic solution. Something like sh:and but where sh:and would look across all objects of sh:path. Am I missing something simple? The one solution that I know works is the one that I cannot use - creating a new property and property shape for each class e.g. st:ownsMovieCompany. If this is the only solution, then I can never use a "generic" property like "owns", "category", etc.... This will result in a property explosion and would rapidly become unworkable in industry-sized models.
