Cross-boundary Metadata Standard: The North American Profile Sharon Shin Federal Geographic Data Committee August 19, 2009
Why? What process? Differences? Go? Wait! Wait. Help! Topics
As members of the international geospatial community we are incumbent to: Employ standards to enhance and support the discovery, access, and application of geospatial data. Provide and international means to document geospatial data resources. Incorporate international references including language and character set. Address new geospatial data structures and models. Include spatial data applications and services. Why change standards.
Canada Natural Resources Canada Ontario Ministry of Natural Resources CGSB-CoG USA Federal Geographic Data Committee FGDC Metadata Working Group INCITS-L1 NAP Editing Committee
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 - ISO 19115
No new attributes. Increase obligations. Modify codelists…deprecate Create new codelists for free text fields. Recommend structure with in text fields e.g. address. Chose to modify/simplify diagrams. Adding best practices to guide implementation. North American Profile: Approach

Ready to go? Not Quite
Proposal the FGDC Standards Working Group to recognize the standard. The WG 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. The NAP is a national standard but…
No Go ahead, Select ISO/NAP Use the NAP Profile as a guide with an ISO 19115 editor. 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 Then were ready? Not Quite. Do you have entity and attribute information
Allows for full description of features (entities and attributes) New work item by INCITs L1 Scheduled completion by next summer/fall. ISO 19110 Methodology for Feature Catalog
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 biological data
Can you create metadata without an editor? Check the ISO editor review on FGDC.gov for vendors who have committed to address the NAP. http://www.fgdc.gov/metadata/geospatial-metadata-tools Metadata Editors
Wait! Wait. Don’t Tell Me! I have existing metadata….
Intergraph developer. 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. FGDC to ISO Conversion Tool
