Topic Version1Published09/11/2015
For StandardRESQML v2.0.1

The following table lists the standards used by RESQML and their respective sponsoring organizations.


Description of Use

XML Schema 1.1

XML Schema Part 1: Structures Second Edition


W3C- World Wide Web Consortium

28 October 2004

Used to define the schema that constrains the content of a RESQML XML document.

XML Schema Part 2: Datatypes Second Edition


W3C-World Wide Web Consortium

Used to define the schema that constrains the content of a RESQML XML document.

Hierarchical Data Format 5 (HDF5)

The HDF Group


Open file formats and libraries used with the RESQML schemas.

Designed to store and organize large amounts of array data, and improve speed and efficiency of data processing.

Geographic Markup Language (GML)

Open Geospatial Consortium (OGC)


The OpenGIS® Geography Markup Language Encoding Standard (GML).

The Geography Markup Language (GML) is an XML grammar for expressing geographical features.

EPSG Codes

International Association of Oil and Gas Producers (OGP)


The European Petroleum Survey Group (EPSG), the globally recognized experts on geodetic issues, has been absorbed into the Surveying and Position Committee of the International Association of Oil and Gas Producers (OGP), which is now the owner of the EPSG database of Geodetic Parameters and assigned codes.

RESQML implementations can use EPSG codes to define a coordinate reference system.


Internet Engineering Task Force


IETF RFC 4122 is a standard for defining universally unique identifiers (UUID). According to the abstract of the specification: "This specification defines a Uniform Resource Name namespace for UUIDs (Universally Unique IDentifier), also known as GUIDs (Globally Unique IDentifier). A UUID is 128 bits long, and can guarantee uniqueness across space and time."

Open Packaging Conventions

Standard ECMA-376Office Open XML File Formats


ISO/IEC 29500-2:2012

Information technology -- Document description and processing languages -- Office Open XML File Formats -- Part 2: Open Packaging Conventions


To address the challenges of the multi-file data sets used in upstream oil and gas, Energistics and its members have developed file packaging conventions based on the Open Packaging Conventions (OPC), a widely used container-file technology that allows multiple types of files to be bundled together into a single package. The Energistics Packaging Convention (EPC) is intended for use with all Energistics standards.

OPC is supported by the two organizations listed in the left column.

Unified Modeling Language™ (UML®)

Object Management Group


UML is a general purpose modeling language, which was designed to provide a standard way to visualize system design. Originally intended for software architecture design, its use has expanded.

Energy Industry Profile of ISO/FDIS 19115-1


To download the EIP: http://www.energistics.org/asset-data-management/energy-industry-profile-standard

Use of EIP replaces the Dublin Core Metadata Elements used in the previous version of RESQML.

The Energy Industry Profile of ISO 19115-1 (EIP) is an open, non-proprietary data exchange standard for data and information with associated spatial coordinates, e.g., geospatial datasets and web services, physical resources with associated location, or mapping, interpretation, and modeling datasets.


RESQML predecessor standard.

RESQML Version 1 replaced RESCUE functionality and addresses some of the key user issues with RESCUE. An E&P industry data exchange used since the 1990s for 3D gridded reservoir models, horizons, faults and structural models, and associated well data.
