Creation of GML application schemas
Principles of the Data Distribution department for the Digital Map Supply:
• Flat structure
• No special Danish characters
• GML 2

Plan & status
• Look at previous mappings
• Find a convenient way to document the mapping
• Make schema transformation in the database
• Set up new services
