Regional, National, & Organizational Profiles Communities with a common need for metadata ISO19115:2003 Geographic Information - Metadata EO Profile Navigation Profile ANZLIC Profile European Profile Metadata Profiles Diagram NATO Profile North American Profile Perfil Latinoamericano de Metadatos Profiles Enable Interoperability Between Communities Courtesy of David Danko
Basic Metadata Functions Locate particular Data in SDI Evaluate characteristics of Data at site Extract Database from site Employ/Use Data to analyze problem
North American Profile The goal for NAP CAN/CGSB 171.3-95 North American Profile Geospatial Metadata Based on ISO 19115/19139 USA CSDGM
Development 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
North American Profile of ISO 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
Modified UML
Example Modifications to 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 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
Summary & 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 Notes: There are many more detailed map projections that have been invented over the centuries. Eras: > Classical Greek; Age of Discovery <Golden Age of Cartography> 18th & 19th Centuries – more precise coordinate projections; 20 century – more specialized projections
Future Cooperation North Perfil American Latino- Profile Americano - Metadata Perfil Latino- Americano de Metadata
