Structure of Metamodel Components

Each metamodels in ModelAnt is represented by a wrapping component, organized as follows:

• the component is named after the metamodel it wraps.
• these components are located in /modelant/metamodel/<component name> directory
• each component sub-directory holds:
  • any metamodel files in XMI 1.1/1.2 and XMI.DIFF format
  • meta.xml file in the format of ANT antlib definition
  • additional files and scripts, that will not be included in the component’s ant.doc
• meta.xml
  • imports modelant-core module using:

    <typedef resource="net/mdatools/modelant/core/antlib.xml"/>

  • defines <component name>.load.metamodel macro, which loads the metamodel files into the metadata repository (MDR).
  • defines <component name>.instantiate macro, which creates an extent for models
  • any other macro defined must have <component name>. prefix
• No other components, macros or scripts should refer the wrapped files explicitly, but the .load.metamodel macro.
• The component directory is zipped in modelant-<component name>.jar
• Use the component’s macros in scripts by:

  <typedef resource="<component name>/meta.xml"/>

Examples:

• the UML 1.3 meta-model is stored in metamodel/uml13 directory
• load the UML 1.3 macros using:

   <typedef resource="uml13/meta.xml"/>

• the UML 1.3 macros are:
  • uml13.load.metamodel
  • uml13.instantiate
