Issues

Issue descriptionPotential solution 

Referential Metadata Subject is currently constrained by Value Domain. Its explanatory text says "GSIM object type may be Product for which there is a list specified in a Value Domain. The Value Domain specifies the list of actual Products for which reference metadata can be reported or authored using this Referential Metadata Structure." but I think creating a list to be able to refer to a subject of referential metadata is too much

  • Add a relationship with several typical subjects such as Questionnaire, Statistical Program, Data Set
  • Add a relationship between  Referential Metadata Subject and Identifiable Artefact 
Referential Metadata Attribute is currently "defined by" Represented Variable. Although cardinality is 0,1, but its definition "role given to a Represented Variable to supply information in the context of a Referential Metadata Structure" seems to imply that it is not optional
  • Change definition (e.g., "characteristic providing qualitative information for a given Referential Metadata Subject") and remove relationship with Represented Variable
