The North American Profile A journey begins Sharon Shin Federal Geographic Data Committee Tribal College Forum Northwest Indian College August 19, 2009
Topics • ISO to NAP process. • General differences between CSDGM and NAP. • Content of NAP. • Best Practices. • Next Steps. • Conversion Tool. • What to do for now.

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
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.

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 shown 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

Portrayal Catalogue • Information to reproduce a map: • Line weight • Color • Font • Etc.
Metadata Entity Set Information • 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)
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
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
Ready to go? Not Quite
The NAP is a national standard but • The FGDC Standards Working Group will review the NAP and the processes by which it arrived • The Standards WG make recommendations to the FGDC Coordination Group and Steering Committee to reject, adopt, or recognize the NAP.
No Go ahead, Use the editor selected Create Metadata!!! Yes Feature Catalog? For the present Create metadata using the NAP AND Log and attach entity and attribute information using CSDGM Section 5 Do you have entity and attribute information
ISO 19110 Methodology for Feature Catalog • Allows for full description of features (entities and attributes) • New work item by INCITs L1 • Scheduled completion by next summer.
Metadata Editors • Can you create metadata without an editor? • Check the ISO/ NAP editor review on FGDC.gov http://www.fgdc.gov/metadata/geospatial-metadata-tools
Wait, I have biological data • The FGDC Biological Data Working Group is staged to present a profile to the NAP for biology • The National Biological Information Infrastructure is gathering a group from the community to develop a profile for biology. • Process start and input will be requested from the biological community as soon as the NAP has final approval.
Wait, I have existing metadata. Do I need to re-write my metadata?
FGDC to ISO Conversion Tool Release • 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.
Lands Information Ontario Agreement • FGDC, FGDC Metadata Working Group, Land Information Ontario FGDC • Update materials, beginning May 1, 2008 and continuing to November 2009
LIO • March 12, 2009 – • 3 hr Webinar • ~ 500 registants • Metadata Best Practices Guide • Metadata- Cost/Benefit Ananlysis • Metadata- Indentifying Key Data and Information Assets • 3 – 5 yr Marketing plan to implement NAP
NAP Training Moduleshttp://www.fgdc.gov/training/training-materials
FGDC Metadata Working Group: Next Steps • Develop NAP training materials content outline for WG members review. • Develop NAP modules for download. http://www.fgdc.gov/training/nsdi-training-program/online-lessons#metadata • Intro to ISO 19115 – • NAP Content – Later this fall • NAP Implementation - Later
What to do for now • Join/monitor FGDC Metadata Working Group/website • NAP Training: Monitor http://www.fgdc.gov/training/nsdi-training-program/online-lessons • Until FGDC recognition /adoption of NAP • Continue use of FGDC CSDGM • Post metadata to clearinghouses • Register clearinghouses to geodata.gov (Geospatial One-Stop).

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.

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…
What’s similar/new with NAP Metadata • Content • CSDGM similar and new elements • Domains and conditionality • Essential, as opposed to core, metadata • Format • UML / XML • Multi-level metadata- • Feature to Dataset Series or Service
