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

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

• 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

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
• Metadata that is absolutely
– based on a solid foundation of
essential for all aspects of
national, regional, and information
spatial data handling
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
– 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
