6. XSD Application Schema Application Schema Data types
AIXM Schema (AIXM-Feature.xsd)
AIXM Data types (AIXM-DataTypes.xsd)
AIXM Abstract Schema (AIXM-AbstractGML-ObjectTypes.xsd)
GML 3.11 Subset (./profile/gml4aixm.xsd)
ISO – Metadata (./iso19139/…/*.xsd)
W3C XLINKS (./xlink/xlink.xsd)

7. Application Schema - XSD
An application schema inherits AIXM and may extend AIXM for specific data needs.
An application schema consists of:
Imports and Includes of AIXM and related schemas
A message collection element
A member feature array element
One or more feature or object elements

8. Application Schema XML
An application schema xml file consists of
A schema message collection element
Message collection is the document root
Message collection detail elements
A members feature array element
One or more features/objects
Feature/object detail elements

9. Root element is a <feature>
XML Document Root
Root element is a <feature>
Contains details about the collection element
Contains a feature member array element
Example
<USNSTransmittalMessageCollection gml:id="_001“>
</USNSTransmittalMessageCollection>

10. XML Member Array Element
Member array contains one or more feature members
Element example
<members_AIXMFeature>
</members_AIXMFeature>

11. XML Member Array has features/objects
Member array contains one or more feature/object elements
Using the NOTAM example, there would be one or more NOTAM Transmittal Message and/or Runway elements
Example
<USNSTransmittalMessage gml:id="_002">
</USNSTransmittalMessage>
<aixm:Runway gml:id="_004">
</aixm:Runway>

12. NOTAM XML Outline
<USNSTransmittalMessageCollection gml:id="_001“>
<-- Message collection details omitted -->
<members_AIXMFeature>
<USNSTransmittalMessage gml:id="_002">
<-- Transmittal message details omitted -->
</USNSTransmittalMessage>
<aixm:Runway gml:id="_004">
<-- Runway element details omitted -->
</aixm:Runway>
</members_AIXMFeature>
</USNSTransmittalMessageCollection>

13. XSD and XML detailed examples
See NOTAM XSDs
USNS-Transmittal.xsd
USNS-Transmittal-Datatypes.xsd
See Sample NOTAM Message xml
Example Runway NOTAMS Collection – 2 msg 2 Runway.xml

14. Web Services Consume and provide XML using the application schema
Web service standards should be used
Prototype being developed with Digital NOTAMs and Obstacles

15. AIXM UML-XSD Implementation
Summary
Build an application schema
Import AIXM and related schemas
Extend AIXM as necessary
Validate the schema
Build application XML
Create XML data (via database, application, web service, etc.)
Utilize application schema to validate XML
Done
