[7] Variable

[duffgui]

The model seems be aligned with DDI 3.2. However, the ConceptualVariable is missing. What is the reason for that?
Moreover, I don't know the current state of the "Conceptual" functional view, but in the last review document the "cascade" relationships between the three types of variables (ConceptualVariable, InstanceVariable and RepresentedVariable) were conformant with GSIM 1.1. For example a ConceptualVariable references a Concept, a RepresentedVariable references a ConceptualVariable and an InstanceVariable references a RepresentedVariable where DDI 3.2 allows a concept to be referenced in any of the three types of variable.
I would recommend to have disco aligned with GSIM 1.1 / DDI4. It would be a bit embarrassing to publish a RDF vocabulary not compliant with the future RDF representation of the standard is based on...

The current solution in Disco is shown in this diagram

The variable cascade in GSIM 1.1. is shown in this diagram

The variable cascade in GSIM 1.5 (draft) is shown in these diagrams

DDI Lifecycle 3.2 has the hierarchy Variable, RepresentedVariable, ConceptualVariable, Concept

Disco has the hierarchy Variable, RepresentedVariable, skos:Concept.

The question is if Disco can be aligned to DDI Lifecycle 3.2 without many changes in the model.
