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
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.

Obligation Terminology: FGDC to ISO FGDC: Mandatory Mandatory-if-applicable Optional ISO/NAP: Mandatory Conditional Optional
ISO UML Diagrams • Decisions?: • Stylize • Simplify • Colorize

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 2 • Metadata as a corporate resource. • Data on hand • Data assessment • Data update • Scheduling • Estimating staffing • Estimating time • Data to be procured
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…
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
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.
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).
