3.2.1.5 Abstraction from Super Classes in the UML Data Model

To ensure consistency of design, all RESQML data objects inherit from the same abstract super classes in the UML model:

• AbstractObject and AbstractDataObject in the Energistics-common package (in UML under common in the package named Abstract) which contains the UUID, Schema Version, and optional EIP metadata citations.
• AbstractResqmlDataObject in the RESQML common package (in UML under resqml, v2.0.1, xsd_schemas, in the package named Common) is a restriction of the AbstractDataObject for which the EIP metadata citations are mandatory.
