MetaData Element

The MetaData element specifies arbitrary metadata that is packaged with the workflow template. This metadata is the starting state of the workflow, and it can be read and modified through the association form, the initiation form, and the workflow engine.

The format of the MetaData section is a set of named tags with values specified as inner contents. The following example creates a property named Instantiation_FormURN with the value "test.urn":

<MetaData>
   <Instantiation_FormURN>test.urn</Instantiation_FormURN>
</MetaData>

Example

The following example shows the contents of an XML file that defines a Workflow feature.
