Access to Contents of Virtual Documents
To work with data in a virtual document, you must be able to identify a specific data item within it. The data item is called a virtual property. An virtual property path is the syntax that InterSystems IRIS uses to specify the location of a virtual property. You can use virtual property paths in the following locations, among others:
-

Data transformations. The following shows an example:
For both Property and Value, the curly braces enclose a virtual property path.
As a consequence, your production can work with a virtual document in much the same way that it works with standard messages.
