1.4.1 What do You “Get” When You Download an Energistics Domain Standard?

Standards are downloaded as .zip files. When you download any one of the domain standards, the download package contains the items listed below, which are further explained in this section. As an example, Figure 1.4.1-1 shows images of the content in the zip file when you download WITSML.

• Common Technical Architecture components (For available resources, see 1.4.2 CTA Resources):

• Energistics commonpackage of schemas. The common package is standardized across all Energistics domain standards; when you download RESQML, WITSML or PRODML, the common package is the same for each. Some common data objects are mandatory (for example, AbstractObject, ObjectReference, objects related to units of measure (UOM), etc.). Other data objects are optional, available for use if wanted (for example, the Data Assurance and Activity Model objects).
• XMI file (UML Model). The UML data model that developers and architects can explore for better understanding of data objects, definitions, organization, and relationships, in context. An XMI file is a format that can be imported by any UML data modeling tool.

• Documentation and Specifications for CTA. Specifications and related documentation for components of the CTA as described in Section 1.4.2 CTA Resources .

• Domain-specific components (For available resources, see 1.4.3 ML Resources):

• Data object schemas. The schemas are bundled into packages, which have been organized based on that domains data model. In addition to the domain objects, each ML has its own “common” data object package for components shared across each domain (i.e., ResqmlCommon, WitsmlCommon, and ProdmlCommon).
• XMI file (UML Model). The UML data model that developers and architects can explore for better understanding of data objects, definitions, organization, and relationships, in context. An XMI file is a format that can be imported by any UML data modeling tool.

• Documentation. ML-specific documentation as defined in Section 1.4.3 ML Resources.
