The Vision:

Realize metadata standards and applications necessary within the petroleum industry to enable effective and efficient discovery and retrieval of geospatial information.

These standards and tools will support both proprietary uses of geospatial data, and the exchange of geospatial data between companies.

Expectation: leverage existing standard specifications, such as FGDC and/or ISO 19115.

2006 Objectives

1. Identify a minimum set of geospatial metadata attributes that should be populated for -

� efficient data search & retrieval,

� adequate characterization of the data set for audit purposes.

2. Identify a set of industry-standard metadata keyword “facets” (dimensions, categories) and associated vocabularies needed to realize the goal of metadata as a “routine component of information delivery and exchange.”

3. Work with ESRI as they begin development of post-9.2 applications to enhance maintenance and use of geospatial metadata.

Proposed Objective #1

� Focused on FGDC metadata specification

� Proven, U.S. Gov’t standard

� Top-level organization: Example attributes

1. Identification

2. Data Quality

3. Spatial Data Organization

4. Spatial Reference

5. Entity and Attribute

6. Distribution

7. Metadata Reference

Proposed Objective #2

The need for “orthogonal” categories

� Categories are fundamentally segmented axes which can define areas (or volumes) in “information space”

Realize metadata standards and applications necessary within the petroleum industry to enable effective and efficient discovery, evaluation, and retrieval of geospatial information resources.

These standards and tools will support both proprietary uses of geospatial data, and the exchange of geospatial data between companies.

The Vision Now …

Realize metadata standards and applicationsnecessary within the petroleum industry to enable effective and efficient discovery, evaluation, and retrieval of geospatial information resources.

These standards and tools will support both proprietary uses of geospatial data, and the exchange of geospatial data between companies.

Leverage existing standards to encourage adoptionwithin the industry, integration into the business, and to exploit existing processes and resources needed for governance and long-term maintenance.

Proposed Foundation

� ISO 19115 North America Profile (NAP)� … a custom implementation of ISO 19115:2003

� ISO 19115:� Established, robust, international metadata standard

� Supports discovery, access, evaluation, delivery, and integration

� ISO 19115 NAP:� Predecessors: Canadian GSB DIDGD (1995) and

U.S. FGDC CSDGM (1998)

� Enables description of

○ Geospatial data sets

○ Non-geospatial resources

○ Services: portals, data catalogs, web mapping services, …

� Applies to multiple levels of information (dataset series � attribute)

20

Proposed Deliverables

� Position Paper

� ISO 19115 NAP / Energy Industry Profile

- Including� Attribute obligations (Mandatory, Optional, Cond’l)

and

� Recommended domain values for selected attributes

� Mappings with other standards (DC, FGDC)

� Assigned custodian organization

21

Guiding Principles

� Be open, inclusive, industry-focused,

business relevant, and current

� Use a directed, managed process based

sound concepts

� Strive for consensus, and use compromise to

maximize shared value of the result

� Use a transparent process and the other

Guiding Principles to resolve issues and

maintain momentum

22

Proposed Partner

� Need a custodian to facilitate adoption, governance, and maintenance of the standards

� Strong preference for acknowledged experience with much or all of the petroleum business value chain; broaden relevance and integration

� Invited Energistics’ partnership in development of the standards, and subsequent custodian role

� 100+ member companies and organizations

� Organization with demonstrated ability to govern and maintain petroleum industry standards, including XML standards for data exchange (WITSML, PRODML)
