The metamodels that you specify in a mapping model determine which
input and output objects you can add to the mapping declarations in the mapping
model. You can add and remove metamodels from a mapping model. You can also
edit the uniform resource indicator (URI) of a metamodel.
You must have
a mapping model open. A
mapping model has .mapping as a file name extension.
Changes to metamodels as a result of iterative development might
impact a mapping model. You might add or remove metamodels as the scope of
a transfomration increases, or if metamodel objects move to different metamodels.
You might edit a metamodel URI if the metamodel location changes.
Check
the Problems view for error and warning information about
missing metamodels. The table on the Input Models and Output
Models tabs also displays warnings if the specified metamodel
paths are incorrect.
To manage the input and output metamodels in a
mapping model:
- In the Mapping Root area of the mapping
editor, right-click the shape that displays the name of the mapping model,
and click Show in properties.
- In the Properties view, click the Input Models tab
or the Output Models tab, depending on the type of
metamodel that you want to manage.
- Complete one or more of the following steps:
- To add a metamodel to the mapping model, click Add Model.
- To specify a different location for a metamodel, in the table, click
the name of the metamodel and click Edit Model URI.
Edit the path to the metamodel and click OK.
- To delete a metamodel from the mapping model, in the table, click
the name of the metamodel and click Remove Model.
- Click .
