# | Description | Rationale | Resolution |
---|---|---|---|
1 | Hierarcy in Concept Domain | There is no hierarchy present in the ConceptDomains in the conceptual model. This can be achieved in two ways.
The simplest way is by adding a recursive link in the conceptual diagram, as well as mentioning this fact in the Core Principle text. There is another way through which this can be achieved, by adding associations between concepts domains. This will allow for finer typing of the relationships between concept domains, not just parent-child relationships. |
The following are enancements to the DSTU from a functional point of view. Some of them are present in the PIM but not in the DSTU, so they might be an oversight. Some operations too are also an obvious oversight, so they are not really enhancements.
Enhancements:
