Energistics Identifier Specification v4.0

This document describes the syntax and semantics of data object identifiers as used within the Energistics family of data exchange standards. The concepts of data object, asset, component, and feature identifiers are pervasive within the WITSML, PRODML, and RESQML specifications. This document is part of the Energistics Common Technical Architecture (CTA) that defines the basis for all of the new Energistics standards.
