4.1 Abstract

Data objects in the abstract package (Figure 4.1-1) are used as the roots of all global elements in Energistics’ XML schemas.

Each domain standard inherits first from its domain common (as described above) and then from Energistics common. The functionality provided from the root-most object—AbstractObject—includes aliasing, simple extensibility, and summary authorship metadata to provide some object traceability.
