3.2 Specifying Relationships between Data Objects

Topic Version1Published11/11/2016
For StandardCTA v2.1

Energistics domain standards use the standard XML hierarchical relationship, for example, where one data object is contained inside another. However, the nature of E&P data and workflows means there are many possible hierarchies or relationships that cannot be modeled in a single hierarchy.

To address these relationships, the CTA includes a data-object reference, which is explained in Section 4.11.1 Relationship Mechanisms: Data-Object Reference and the Energistics Identifier Spec.

Additionally, relationships are specified in the context of an Energistics Package, which is explained in the EPC Specification.
