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
![Page 5: Handshake across the border… The North American Profile](https://reader035.vdocuments.us/reader035/viewer/2022062315/56814f58550346895dbd0457/html5/thumbnails/5.jpg)
ISO 19115
•Enables describing:– Geospatial data sets.– Maps.– Non-geospatial resources.
– Services: portals, web mapping services.

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.

Organization and Terminology
•FGDC – Sections– Elements – Compound Elements– Domains
•ISO / NAP – Classes– Subclasses– Attributes – Domains
![Page 10: Handshake across the border… The North American Profile](https://reader035.vdocuments.us/reader035/viewer/2022062315/56814f58550346895dbd0457/html5/thumbnails/10.jpg)
Obligation Terminology: FGDC to ISO
•FGDC:– Mandatory– Mandatory-if-applicable– Optional
•ISO/NAP:– Mandatory– Conditional– Optional

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
![Page 23: Handshake across the border… The North American Profile](https://reader035.vdocuments.us/reader035/viewer/2022062315/56814f58550346895dbd0457/html5/thumbnails/23.jpg)
Best Practice 2
• Metadata as a corporate resource.– Data on hand
• Data assessment • Data update
– Scheduling– Estimating staffing– Estimating time
– Data to be procured
![Page 24: Handshake across the border… The North American Profile](https://reader035.vdocuments.us/reader035/viewer/2022062315/56814f58550346895dbd0457/html5/thumbnails/24.jpg)
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…
![Page 25: Handshake across the border… The North American Profile](https://reader035.vdocuments.us/reader035/viewer/2022062315/56814f58550346895dbd0457/html5/thumbnails/25.jpg)
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
![Page 26: Handshake across the border… The North American Profile](https://reader035.vdocuments.us/reader035/viewer/2022062315/56814f58550346895dbd0457/html5/thumbnails/26.jpg)
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.
![Page 27: Handshake across the border… The North American Profile](https://reader035.vdocuments.us/reader035/viewer/2022062315/56814f58550346895dbd0457/html5/thumbnails/27.jpg)
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).

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.
