North American Profile

Geospatial Metadata

Based on ISO 19115/19139

Development ApproachDevelopment Approach

• Requirements analysis– Past experience with metadata standards implementation

• Cross-table development (FGDC-ISO 19115)• Modified UML

– Promote options to obligations– Extended codelists– Added codelists

88

North American Profile of ISO North American Profile of ISO 19115:2003 Metadata (NAP-Metadata)19115:2003 Metadata (NAP-Metadata)• Selection of items from ISO19115:2003• Promotion of optional fields to mandatory• Extension of code lists

– Addition of values to existing code lists– Addition of code lists

• Introduction of a multilingual register– Compliant to ISO19135:2005 on registers– English and/et Français (and potentially Spanish)– Metadata items– Code lists

• Register will be accessible on the Web– XML document– Web Services– Web Browser

Example Modifications toExample Modifications to ISO 19115 Reflected in NAP ISO 19115 Reflected in NAP

• Extension of Code Lists

• Language (M,1)– Language of metadata using standard ISO 3 letter

codes– Language Country Code: e.g. ENG, FRA…..

• Locale (C, Repeatable)– Locale– Other languages used in metadata

Current Status of NAP ProjectCurrent Status of NAP Project

• Version 1.0 Circulated in February, 2007• Currently reviewing comments & updating• Will circulate Version 2.0 shortly• Hope to have Profile competed by the end

of the year

1212

Summary & ConclusionsSummary & Conclusions

• Much Progress since 2005• Cultural & Linguistic Adaptability• User-friendly Specifications• Promotes Wider Use of Profile• Continue to Circulate NAP Documents• Develop Application Tools for Future
