4. Introduction
• Development of an exchange format for soil and terrain
datadata
• Based on interoperability principles
• Separate the data from the application
• Use existing interfaces

6. XML
• XML is the language of the web
 machine and human readablemachine and human readable
 standard interfaces (OGC & ISO) use XML
 structured and addressable elementsstructured and addressable elements
 Integration
• Schema - describes the data
• Instance document – the data

7. GML
• Geography Markup Language
• XML grammar for structuring and exchanging
geographic data
A li ti h ll iti t• Application schemas allow user communities to
add there own grammar based around GML
• Interoperability of geographical datasets led by• Interoperability of geographical datasets led by

9. SoTerML design
• Data model (UML)
• XML schema (XSD)
• Attribute pattern

10. Attribute pattern design
• Separation of attributes from class hierarchy

11. Attribute pattern design
• Acceptable value defined in the attribute pattern
