Hi Karen, thanks for your comment on requirement https://www.w3.org/2014/data-shapes/wiki/Requirements#Declarations_of_Property_Min.2FMax_Cardinality in which you ask how to represent a constraint such as "there must be one instance of classX". While I was responding, I noticed that we did not yet have a story about "global" constraints that are evaluated independently from specific instances or classes. I propose to call them "static constraints" and have added a corresponding requirement: https://www.w3.org/2014/data-shapes/wiki/Requirements#Static_Constraints Although I am confident that this requirement is important, I had a hard time finding motivating User Stories in our current catalog. I would therefore encourage you (or anyone else) to write down your requirement as a User Story and add a cross-link if you are supportive of the Static Constraints requirement. Thanks Holger
