The Metadata Work Group is composed of Energistics members and contributing organizations working on Metadata profile specifications and usage guidelines.
Origin of Metadata Work Group
In early 2009, Energistics was invited to participate in an ad-hoc work group of industry organizations considering the formal development of guidelines and standards for the use of metadata.
This group grew out of an earlier working group in the ESRI Petroleum User Group (PUG) focused on GIS datasets, but the group established an objective to ultimately address all E&P data with geographic references. The work group joined the Energistics Asset & Data Management Special Interest Group (SIG) formally in September 2009. The Asset & Data Management SIG is responsible for reviewing and endorsing the specification produced by the Metadata Work Group Steering Committee.
The initial objective for the Metadata Work Group was to develop a metadata profile specification for discovery, evaluation and retrieval of information and physical resources of interest to the energy industry. This objective was achieved with the release of the Energy Industry Profile of ISO 19115-1:2014 (“EIP”) v1.0 metadata specification. The objective of the Work Group is now the ongoing maintenance and community-guided enhancement of the EIP specification.
The intent of this profile is to help improve operational efficiency within the industry through adoption of metadata standards, guidelines and best practices to enable efficient cataloging, discovery, evaluation, and retrieval of information resources, regardless of whether those resources are hosted internally or externally to an organization.
The intended audience and stakeholders of this initiative include energy companies and consortia, data and information providers, software vendors, government agencies, and academia.
The initial focus of the effort is on metadata for structured and unstructured information resources which have associated spatial coordinates. For example, geospatial data sets, mapping, interpretation, modeling project data sets, and geospatial web services are to be included. The long-term vision of information resources to be addressed includes data sets and documents with location specified using place names (e.g., Ghawar field).

Related Standards Activities
Metadata Work Group activities reference ISO 19115 and related standards, which are managed through ISO TC 211. Energistics’ interests in TC 211 also extend to the relationship with Open Geospatial Consortium (OGC), some of whose standards are being absorbed into ISO via TC 211.
Energistics is a Class-A Liaison for TC 211.
Metadata Work Group Leadership
Duties: Produces the specification and steers the activities of participants.
Duties: Serve as Subject Matter Experts (SMEs) and provide feedback and input to the development of the specifications.

ISO publishes ISO 19115-1:2014 as an “International Standard” (IS) on March 19 and votes in June to progress ISO 19115-3 from the “Draft Technical Specification” (DTS) to the “Enquiry Stage” to test its readiness for publication as a “Technical Specification”.
In June, the ISO 19115-3 project team produces an XML schema conformant with the ISO/DTS 19115-3 specification and ISO 19115-1 progresses to the “Final Draft International Standards” (FDIS) state in November following a vote by TC 211 member countries.
The Energy Industry Profile (EIP) is updated to align it with ISO/FDIS 19115-1 and ISO/DTS 19115-3.
Work continues on revisions to EIP Version 1.0 based on industry feedback. The Metadata Work Group begins working with Esri to create specifications for an EIP Prototype, a geoportal implementation customized for Energistics and the EIP v1.0 profile. Four Energistics members – BP, Chevron, ExxonMobil, and Pioneer Resources – sponsor the EIP Prototype project.
A Statement of Work (SOW) is signed for Esri’s participation in the building of the EIP Prototype. The prototype project executes from October 3 to December 20, 2012
After ISO 19115-1 progresses to the “Committee Draft” (CD) state in January, the Metadata Work Group conducts an April workshop for interested participants at the 2011 Esri Petroleum User Group conference. The workshop covers ISO 19115 and its revision process, as well as the development of EIP v1.0.
In mid-2011, the EIP is released for community comment. Metadata Work Group activities focus on finalizing the release candidate document and review materials for the remainder of the year.
In October, Energistics submits a “New Work Item Proposal” to ISO/TC 211 to begin work on the technical specification for an XML encoding of ISO 19115-1. ISO member countries vote to advance ISO 19115-1 in December to the “Draft International Standard” (DIS) state.
In early 2010, the work group completes stage 2 of the Energistics Standards Life Cycle and compiles requirements for an Energy Industry Profile based on ISO 19115. A Request for Comment is distributed to active participants and results compiled as part of the formal requirements gathering process. These requirements serve as input to the EIP standard development.
In addition, work group members analyze suggested changes to the base ISO 19115 standard, and in mid-2010, provide comments back to the ISO 19115 Revision Project Team. The goal is to affect ISO-based standard changes based on requirements from energy industry participants.
The ISO 19115 Revision Project Team progresses the evolving revision to “Working Draft” state (i.e., to ISO/WD 19115-1) in late 2010.
