  1. A look to the past for the future-The North American Profile Sharon Shin Metadata Coordinator Federal Geographic Data Committee

  2. The Past - FGDC Content Standard for Digital Geospatial Metadata • Information Exchange Forum on Spatial Metadata- June 16-18, 1992. • Executive Order 12906, 1994 • EO 13286, 2003 • Content Standards for Digital Geospatial Metadata Version 1 1995, Version 2 1998

  3. ISO19115:2003 Geographic Information - Metadata State Profile Navigation Profile ANZLIC Profile European Profile NATO Profile North American Profile EO Profile Perfil Latinoamericano de Metadata The Future:Regional, national, & organizational profiles

  4. North American Profile of ISO 19115 Metadata North American Profile of ISO 19115 Metadata Co-located Meetings Parallel Development MOU between Canada and the USA

  5. What is the NAP • Community profile of ISO 19115 Geospatial Information – Metadata • Addresses metadata for geographic products. • Negotiated content between the ANSI and CGSB representatives. • Format: Profile with “best practices” and simplified diagrams for training, UML in annex

  6. NAP Metadata: Implications –Good News Multi-level metadata • Data Series - wetlands • Dataset - Paducah wetlands • Feature Type - marsh • Feature Instance - Mandy’s Marsh • Attribute Type - salinity • Attribute Instance - actual % water salinity

  7. ISO Metadata: Core Elements mandatory

  8. NAP: Essential Metadata • Requires reviewing the entire standard to determine what is minimal metadata for each user. • Metadata Record Information – 7 mandatory • Identification Information- 3 mandatory All optional with the number of mandatory attributes/subclasses: • Data Quality 1 • Maintenance Info 1 • Descriptive Keywords 1 • Resource Constraints 0 +1 • Aggregate Info 1 • Spatial Representation Info • 4 + 7 • Reference System Info 1 • Content Info 2 or 3 + 2 • Distribution Info 2 +1

  9. Attribute Consistency Logistical Consistency Completeness Report Positional Accuracy Lineage Scope (M) Report (C) Completeness Logical Consistency Positional Consistency Thematic Accuracy Temporal Accuracy Lineage (C) Data Quality CSDGM NAP

  10. Maintenance Information Maintenance and Update Frequency (M) – code list Date of Next Update • User Defined Maintenance Frequency • Updated Scope • Update Scope Description • Maintenance Note • Contact – responsible party

  11. Application Schema Supports description of associated: • published data models • custom data models • A vector map, with points, polylines and polygons. • Filename extension.gml • Developed byOpen Geospatial Consortium • Type of formatGeographic Information System • Extended fromXML

  12. Service Metadata Supports description of associated: • data distribution portals • web mapping applications • data collaboration networks • project websites

  13. The Future - Implementation

  14. Lands Information Ontario Aggreement • FGDC, FGDC Metadata Working Group, Land Information Ontario FGDC • Time period: 12 months, beginning May 1, 2008 • Update materials, beginning May 1, 2008 and continuing to November 2009 • Collaborative period between FGDC and LIO: • July 01, 2008 – February 28, 2009 (in-kind contribution of 100 days @ $300/day) • Activities: • Development and verification of materials initiated by Land Information Ontario and theFederal Geographic Data Committee.

  15. Graphic Representation

  16. Graphic Representation NAP

  17. Graphical Representation NAP • format based upon ISO 19139 (xml) vs. 19115 (uml) • hyperlinked and printable doc

  18. Implementation Guide • Guidance beyond best practices in NAP. • Assists metadata creators

  19. NAP Training Moduleshttp://www.fgdc.gov/training/training-materials

  20. NAP Guidance Documents

  21. Tools • FGDC sponsored ISO metadata editor review. • URL: http://www.fgdc.gov/participation/working-groups-subcommittees/mwg/ • Validation tool ? • CSDGM to ISO 19115 Conversion tool • Intergraph • Shareware

  22. Contact Sharon Shin- Metadata Coordinator sshin@usgs.gov Lynda Wayne- LWayne@geomaxim.com

  23. Crosswalk

  24. Modified UML

  25. ISO 19139 Validation NAP Validator http://www.isotc211.org/2005/

  26. NAP Metadata: Content- Domains and Conditionality • Fewer mandatory elements • Fixed domains and code lists in place of free text to control vocabulary and improve discovery • More optional elements • Increased use of modular content extent citations time period responsible partycontact address online resource and more…

  27. NAP Metadata: New (non-CSDGM) Content • International elements Data / Metadata Language PT Locale- to record other languages used in the metadata • Lacking elements ISO Topic Category– 19standardized subject categories to facilitate data discovery
