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 19139 – Metadata (./iso19139/…/*.xsd) W3C XLINKS (./xlink/xlink.xsd)

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

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

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>

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

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>

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>

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

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

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
