Provides the data types and descriptor classes for the <emph>Open MBean</emph>s. Open MBeans are provided in order to aid interoperability with non-Java management systems. Unlike normal MBeans, which make use of any Java data type, Open MBeans use a restricted set of types which can then be mapped over remote connections, including to non-Java systems.

Normal MBeans are described using an instance of {@link javax.management.MBeanInfo} with appropriate representations of the attributes, constructors and operators associated with the bean. Open MBeans are described in the same way, but by using subtypes of these entities, which type the bean data using instances of {@link javax.management.openmbean.OpenType}. Open types differ from Java types, and are explicitly specified in order to obtain interoperability with other systems.
