You can define classes to connect to a custom standardization engine instead of the Master Index Standardization Engine. Specify the names of the custom classes you create in the standardizer-api and standardizer-config elements of mefa.xml. Follow these guidelines when implementing custom standardization engine classes.
Implement the com.sun.mdm.index.matching.StandardizerAPI interface to communicate with the standardization engine.
Implement the com.sun.mdm.index.matching.StandardizerEngineConfiguration interface to retrieve any configuration values the standardization engine requires for initialization.
You can also define custom standardization rules to plug in to the Master Index Standardization Engine. For more information, see Understanding the Master Index Standardization Engine.
