Welcome to the technical resources and the specifications for elements of the Common Technical Architecture. Below is an explanation of the elements. You can find  each of them on the downloads page.

Energistics Unit of Measure Standard (UOM)

The units in UOM are oriented towards use in software.  The Energistics Unit of Measure work group generated the unit names, symbols, derived units and conversion factors with an eye towards implementability in software and databases, not so much for other uses like writing academic papers.  There are other resources – like NIST 811:2008 – to aid in preparing manuscripts.

Energy Industry Profile Standard

The Energy Industry Profile (EIP) of ISO 19115-1:2014 is an open, non-proprietary exchange standard for metadata used to document information resources, and in particular resources referenced to a geographic location, e.g., geospatial datasets and web services, physical resources with associated location, or mapping, interpretation, and modeling datasets.

Energistics Packaging Conventions (EPC)

The Energistics Packaging Conventions (EPC) are supported by these standards organizations:
