belonging to heterogeneous models and diagrams.

Understanding object mapping
You create a mapping between XML Model objects and PDM or OOM
objects to setup a structure for data movement and transformation. Data
comes from a data source and is loaded in an XML model.
In an XML model, the data source can be a PDM representing a database or
an OOM representing classes.
Object mapping consists in linking objects in a PDM or an OOM data source
to objects in an XML model.
Defining data sources in an XML model
You create a data source to define where (in which PDM or OOM) data
should be extracted to be transferred to an XML model.
When you define a data source, you have to declare PDMs or OOMs in the
list of data source models. A data source can contain several models, you can
select the source models among a list of models opened in the current
workspace.
A model can contain several data sources.
