ISO/TC 211Standards development approach
Develop standards through procedures established by the American National Standards Institute (ANSI) and InterNational Committee for Information Technology Standards (INCITS).
Bring together subject matter experts from all levels of government (Federal, State, and local), academia, and the private sector to develop data standards for Framework themes
Provide UML modeling support
Transform UML data models into XML/Geography Markup Language schema documents

ISO/TC 211
Application of ISO 19109• Use General Feature Model to describe
geographic features (applies to geodetic control, cadastral, hydrography, transportation, and government units boundaries themes)
• Build Application schema in UML

ISO/TC 211Application of ISO 19115
Framework Data Standards will be compliant with ISO 19115
Some elements listed as optional in ISO 19115 are mandatory for Framework Data Standards
examples: Metadata standard name, Metadata standard version, Dataset purpose, Dataset progress, Dataset maintenance and update frequency
ISO 19115 elements closely match elements in FGDC Content Standard for Digital Geospatial Metadata, FGDC-STD-001-1998 (version 2.0); therefore, data standards will be compliant with FGDC standard
FGDC standard lacks metadata elements for language and character set
12
ISO/TC 211Application of ISO 19123
Application of ISO 19123 (for digital orthoimagery and elevation themes)
Digital orthoimagery adopts ISO 19123 classes such as CV_Coverage, CV_ContinuousQuadrilateralGridCoverage, CV_Grid, CV_GridValuesMatrix
Elevation standard models data as simple discrete coverages
13
ISO/TC 211Application of ISO 19123
The draft elevation standard models data as simple discrete coverages
Point coverage Curve (line) coverage
Grid coverage Surface coverage
14
ISO/TC 211Application of ISO 19136
UML data models in .xmi format (defined by OMG) were transformed to XML/Geography Markup Language (GML) schemas through UGAS software tool
The XML/GML schema documents can be used to create, validate, and process geographic information with XML parsing and validation software.
Activity supported through Information Interoperability component of the Open Geospatial Consortium’s Open Web Services 2.0 Testbed

ISO/TC 211Status of Framework Data Standards
Standards project is registered as INCITS Project 1574-D, Geographic Information – Framework Data Content Standard
Objective is an American National Standard (ANS) Standards initially developed through Geospatial One-
Stop e-government initiative, but FGDC has assumed leadership for further development
Draft standards out for public review until October 30, 2004
The FGDC funded projects across the U.S. to serve and use Framework data over the web using the Open Geospatial Consortium’s Web Feature Service (WFS) specification.
