After importing Rational Data Architect v7.5.2 Logical and Physical data models into ERwin, I am (4295216)

Solution:

Importing from Infosphere/Rational Data Architect (RDA) from a file requires dependencies and does need the RDA to be installed.

The bridge depends on a set of plugin files that you can find under your Rational Data Architect's plugins directories in version 6.1 or in the shared directory in version 7.

Here is the list of ids for the required plugin files:

org.eclipse.gmf.runtime.notation
org.eclipse.emf.common
org.eclipse.emf.ecore.xmi
org.eclipse.emf.ecore
org.eclipse.emf.commonj.sdo
org.eclipse.emf.ecore.sdo
org.eclipse.wst.rdb.models.sql
com.ibm.db.models.db2
com.ibm.datatools.datanotation
com.ibm.db.models.logical
com.ibm.db.models.oracle
com.ibm.db.models.teradata

Please configure the 'Rational Data Architect install directory' option to specify the installation path of Rational Data Architect.
