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

• 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:

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)

Page 22: ISO/TC211 Geographic information/Geomatics ISO 19115 Geographic Information - Metadata

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

Page 23: ISO/TC211 Geographic information/Geomatics ISO 19115 Geographic Information - Metadata

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
