5.4.1 Relationship Mechanisms: Data Object Reference

The data object reference is a special mechanism in the schema (DataObjectReference in the Energistics common package of the schema/EA model) that is used to specify relationships between and among RESQML data objects. The reference mechanism is specified in the data object schema and includes:

• The UUID(s) that the data object references.
• The nature of the reference relationship. For example, one data object may "interpret" another data object or one data object may "represent" another data object. Possible relation types include:

• Interprets
• Represents
• IsSupportedBy
• isbasedOn

Because these relationships are specific, they are entered as relation names in the UML model in the EA project.
