Basic Metadata FunctionsBasic Metadata Functions
• Locate particular Data in SDI• Evaluate characteristics of Data at site• Extract Database from site• Employ/Use Data to analyze problem

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
