5 Previously 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

7 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. 7

8 Proposed Objective #1 Focused on FGDC metadata specification Proven, U.S. Gov t standard Top-level organization: 1. Identification 2. Data Quality 3. Spatial Data Organization 4. Spatial Reference 5. Entity and Attribute 6. Distribution 7. Metadata Reference Example attributes Title Author Source(s) Publication used date Processing Version history Abstract Distributor contact Coordinate Distribution Bounding coordinates ref. liability system Technical Geodetic Keywordsdatum prerequisites Access Metadata constraints date Metadata Use constraints contact Point of contact Online linkage (URL) Native dataset environm t 8

9 Proposed Objective #2 The need for orthogonal categories Categories are fundamentally segmented axes which can define areas (or volumes) in information space Nigeria Discipline Geophysics 9

17 The Vision Now 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. Leverage existing standards to encourage adoption within the industry, integration into the business, and to exploit existing processes and resources needed for governance and long-term maintenance. 17

18 Proposed Foundation ISO 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 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) 18

19 ISO NAP Top-level metadata categories & attributes: Data Set Information Application Schema Content Distribution Identification Portrayal Catalogue Quality Reference System Spatial Representation URI Metadata Information Character Set Constraints Contact Date Stamp File Identifier Language Maintenance Standard Name Standard Version 19

20 ISO Community Profiles An ISO Profile is a custom implementation of the base standard tailored to a specific Community Standard Broad/complex Generic Optional Undefined domains Profile Narrow focus/often simpler Specific Mandatory Explicit Domains codelists Easier implementation 20

21 Proposed Deliverables Position Paper ISO 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

22 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

23 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) 23
