Application Schema(s)

Lists all the Application Schema Packages under the selected source Package.

Click on a Package to display its details, as well as any of its child «Leaf» stereotyped Package details, in the Package Details panel.

GML Application Schema will not be generated for any Package in the list that is unchecked.

Package Details

Against each of the child «Application Schema» and (optionally) «Leaf» stereotyped Packages (if any), enter a filename. To do this, double-click on the Package name in the list and, on the 'Package Details' dialog, review or complete these fields:

  • 'Stereotype' - The stereotype of the selected Package
  • 'Filename' - (Optional for a «Leaf» stereotyped Package) Click on the button and type the name of the .xsd file into which the GML Application Schema is to be generated; the filename must be in the same file path as selected in the 'Directory' field on the 'Generate GML Application Schema' dialog
  • 'Namespace' - (Not required for a «Leaf» stereotyped Package) Type in the namespace for the selected Package
  • 'Namespace Prefix' - (Not required for a «Leaf» stereotyped Package) Type the abbreviated value that represents the Namespace

Note that:

  • The value of the 'Filename' field will be saved as the value of the tag xsdDocument on the Package
  • The value of the 'Namespace' field will be saved as the value of the tag targetNamespace on the Package
  • The value of the 'Namespace Prefix' field will be saved as the value of the tag xmlns on the Package

Notes

  • The MDG Technology for GML is available in the Professional, Corporate, Unified and Ultimate editions of Enterprise Architect
  • A «CodeList» stereotyped Class with the tag 'asDictionary' set to True will be exported as a separate XML file to the directory specified in the 'Directory' field, with the filename CodeList_<classname>.xml (where <classname> is the name of the «CodeList» stereotyped Class)
  • Using the configurable file GMLStereotypes.xml in the Sparx Systems > EA > Config > GML folder, you can specify aliases for the standard GML stereotypes; the GML Application Schema Generator will also consider these aliases during Schema generation
  • Association Class is specific to GML 3.3; when generating GML 3.2.1 Application Schema, the Association and Class of an Association Class are treated as separate entities
