Work Item 15-Metadata Scope...the schema required for describing geographic information and services....information about the identification, the extent, the quality, the spatial and temporal schema, spatial reference, and distribution of digital geographic data....applicable to the cataloguing of datasets, clearinghouse activities, and the full description of datasets for a wide range of geographic applications. …applicable to geographic datasets, dataset series, and individual geographic features and attributes...may be used for other forms of geographic data such as map, charts, textual documents

Background Who is involved –ISO/TC211 member nations –Liaisons Development history –Development cycles –National/regional/community standards

Comprehensive dataset metadata profile Basic profile applicable to a broad range of information communities Defines complete range of metadata required to identify, evaluate, extract, employ and manage geographic datasets Defines a comprehensive metadata application schema (UML model) which provides an implementable profile Provides a XML DTD based on the application schema

Comprehensive metadata application schema

Comprehensive profile XML Encoding XML DTD XML Document 2 XML DTD XML Document XML Document 1 The Document Type Definition (DTD) defines the tags, constraints, attributes, structure, domains etc The XML document defines the content (the dataset metadata) The DTD can be located: –within the document –within the same folder/computer/server C:\My Documents\My Metadata.dtd –within the Internet

Comprehensive Profile Application ISO-Comprehensive Geographic Metadata.dtd DCW.xml Recommended Core Metadata Schiphol Environmental Impact data.xml Full comprehensive metadata comprised of over 300 metadata elements NATO Specific.dtd VMap 1-NL.xml NATO cataloging profile which includes ISO recommended core plus additional selected metadata elements. The NATO DTD defines NATO specific metadata and code lists North Sea Soundings.xml only 12 mandatory metadata elements

Proposed Implementations US FGDC –Edition 3 will be a profile of ISO ANZLIC –developing ISO compliant ANZLIC profile Saudi Arabia –Ar-Riyadh Development Authority developed draft profile of ISO NATO –STANAG 7148 Catalog Metadata for Geographic Information (under development)

Summary ISO development –based on a solid foundation of national, regional, and information community standards –has broad global participation –has gone through formal development cycles ISO Standard –based on a harmonized object model –designed to fill a broad range of requirements –extensive use of codelists -language interoperability –recommended core with a full comprehensive profile Metadata that is absolutely essential for all aspects of spatial data handling –Locate –Evaluate –Extract –Employ Metadata in a global standard –Allows expanded networks –Provides a common understanding –Global Interoperability Metadata: the foundation for a Global Spatial Data Infrastructure

Impact to CINTEX/CIP Formal review of next version Discuss creation of a CIP/CEOS Profile Do we need a CIP 3 or a CIP 2.5 Alignment of Code lists and Keywords
