	config/crud/src/main/java/com/redhat/lightblue/config/crud/ControllerConfiguration.java
	config/crud/src/main/java/com/redhat/lightblue/config/crud/CrudManager.java
	config/metadata/src/main/java/com/redhat/lightblue/config/metadata/MetadataManager.java
	config/metadata/src/test/java/com/redhat/lightblue/config/metadata/TestConfig.java
