DaveDanko/Lou Reich/Yonsook EnloeCINTEX Subgroup Meeting
Briefing Agenda
• ISO 19115 Overview– Scope– Background– Schedule
• Version 3 Technical Overview– Basic Concepts– ISO 19115 Profiles
• Summary – Technical Summary– Potential Inpacts to CINTEX/CIP
Work Item 15-MetadataScope
• ...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

Comprehensive datasetmetadata 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

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
• http://www.opengis.net/geographicMetadata.dtd

Proposed Implementations
• US FGDC– Edition 3 will be a profile of ISO 19115
• ANZLIC– developing ISO compliant ANZLIC profile
• Saudi Arabia– Ar-Riyadh Development Authority developed draft profile
of ISO19115.2
• NATO– STANAG 7148 Catalog Metadata for Geographic
Information (under development)
Summary• ISO 19115 development
– based on a solid foundation of national, regional, and information community standards
– has broad global participation– has gone through formal development
cycles
• ISO 19115 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
