Mapping models, also called
mapping files, are instances of Eclipse Modeling Framework (EMF) metamodels,
also called Ecore models, that contain references to the metamodels
that are being mapped. When you create a mapping project, the authoring
tools create a mapping model in the project by using the input and
output model or models that you specify. A mapping project contains
at least one mapping model. Creating multiple mapping models in a project
encourages the reuse of maps in other mapping projects. Before you begin
You must have a mapping project
in your workspace.
