  1. Handshake across the border…The North American Profile Sharon Shin Federal Geographic Data Committee

  2. Topics • ISO to NAP, the journey and process. • General differences between CSDGM and NAP. • Content of NAP. • Best Practices. • Next Steps. • Conversion Tool. • What to do for now.

  3. NAP Editing Committee Canada Natural Resources Canada Ontario Ministry of Natural Resources CGSB-CoG Members USA Federal Geographic Data Committee FGDC Metadata Working Group INCITS-L1 Members

  4. NAP Editing Committee Meetings

  5. North American Profile - ISO 19115 • Goal. • Meet the geospatial metadata implementation needs of the US through the development of a Profile guidance document. • Objectives. • Comprehensive profile. • Identical content with Canadian Profile. • Release by ANSI same date and time as CSB. • Results in North American Profile: NAP

  6. ISO 19115 • Enables describing: • Geospatial data sets. • Maps. • Non-geospatial resources. • Services: portals, web mapping services.

  7. North American Profile: Approach • No new attributes. • Increase obligations. • Modify codelists…deprecate • Create new codelists for free text fields. • Recommend structure with in text fields e.g. address. • Modify/simplify diagrams. • Adding best practices to guide implementation.

  8. ISO 19115 and other ISO Standards Language Codes County Codes Conceptual Schema Language Profiles Spatial Schema Temporal Schema Rules for Application Schema Methodology for Feature Cataloging Spatial Referencing by Coordinates Quality Principles Quality Evaluation Procedures Metadata, Technical Corrigendum 1 Encoding Services Geographic Information Services Geodetic codes and Parameters Location Based Services- Tracking and Navigation GML XML OGC’s Web Services Common Specification

  9. What is different/same between FGDC CSDGM and the NAP?

  10. Organization and Terminology FGDC Sections Elements Compound Elements Domains ISO / NAP Classes Subclasses Attributes Domains

  11. Obligation Terminology: FGDC to ISO FGDC: Mandatory Mandatory-if-applicable Optional ISO/NAP: Mandatory Conditional Optional

  12. FGDC CSDGM Graphic Representation

  13. ISO UML Diagrams • Decisions?: • Stylize • Simplify • Colorize

Metadata Entity Set Information Identification Information Dataset Identification Service Identification Constraints Data Quality Information Maintenance Information Spatial Representation Information Reference System Information Content Information Portrayal Catalogue Information Distribution Information Application Schema Information NAP Content Major Classes

  16. Metadata Entity Set Information File Identifier (M) Language (M) Character set (M) Parent Identifier Hierarchy Level (M) Contact (M) Date Stamp (M) Metadata Standard Name (M) Metadata Standard Version Data Set URI Locale (C)

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

  18. 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

  19. Service Identification • Attributes (5 Mandatory) • Resource Maintenance Information • Graphic Overview • Descriptive Keywords • Resource Specific Usage • Resource Constraints • Aggregation Information • Operates On • Contain Operation (M)

  20. Application Schema • Name (M) • Schema language (M) • Constraint language (M) • Schema ASCII • Graphics file • Software development file • Software development file format

  21. Portrayal Catalogue • Information to reproduce a map: • Line weight • Color • Font • Etc.

  22. Metadata Entity Set Information7 mandatory attributes • Identification Information M (M6/) • Data Identification C (M6/) • Service Identification C (M5/M1) • Constraints O () • Data Quality Information O(M1/) • MD Maintenance O (M1/) • Spatial Representation O () • Reference System Information C (M1/M1) • Content Information O (C2/) • Portrayal Catalog O (M0 / M1) • Distribution Information O () • Application Schema O(M3/) Class Name – Obligation (Mandatory attributes / Mandatory subclasses)

  23. Best Practice • Create metadata as the project progresses • Information is at hand • Brain drain is at a minimum • Create Template • Internal use • Contracted Data • Create Template • Internal use • Contracted Data

  24. Best Practice • Metadata as a corporate resource. • Data on hand • Metadata assessment • Metadata Maitenance • Scheduling • Estimating staffing • Estimating time • Data to be procured • Contract Metadata • Provide contractor with template to assure content level • Metadata Maintenance

  25. NAP Editing Committee: Next Steps • Review of Comments Fall 2007. • Review of adjudication of comments. • Final edit prior to submission to standards bodies. • US: Submission to American National Standards Institute: Fall 2007. • ANSI review, vote, Adoption….?. • FGDC Standards Working Group…

  26. FGDC Metadata Working Group: Next Steps • Develop NAP training materials content outline for WG members review. • Develop NAP modules for download. • Intro to ISO 19115 • Intro to NAP • NAP Content

  27. FGDC to ISO Conversion Tool Release – Fall 2007 • XML- conversion format. • Conversion tool format: XSLT. • Standalone. • Plan to include source code. • Conversion tool to be delivered via shareware site. • Announced through FGDC.gov and FGDC Metadata Working Group.

  28. What to do for now • Monitor fgdc.gov for Public Review announcement. • Announcement made directly to FGDC Metadata WG. • Join/monitor FGDC Metadata Working Group/website • NAP Training: Monitor http://www.fgdc.gov/training/nsdi-training-program/online-lessons • Until ANSI adoption and FGDC recognition /adoption of NAP • Continue use of FGDC CSDGM • Post metadata to clearinghouses • Register clearinghouses to geodata.gov (Geospatial One-Stop).

  29. Contact Information • Sharon Shin • 303-202-4230 • sshin@usgs.gov

  30. FGDC: Previous NAP Activities • Introduction to ISO 19115 Workshop. • January 13-14, 2006. • NAP Training Materials Workshop. • December 5-6, 2006. • Isearch (Isite) extended to address ISO 19115 and will be extended for ISO 19139.
