"Beans" in the interoperability server describe objects passed as XML content in the SOAP body element. They are typical java beans. They are populated and red by the built-in marshalling framework of axis and that of castor. Various types of helper classes used for marshalling, un-marshalling, and display/editing accompany them. This highest package contains all TIE types some of which are shared with auxiliary services. The beans defined in the opengis sub-packages correspond to the Open GIS Consortium, Inc. (OGC) http://www.opengis.org Web Map Context Documents http://www.opengis.org/docs/03-036.pdf data types. The "context" package contains the data type to define and save a map view state and group various map view states into collections. The package contains data types defined by the OGC filter, or query specification. The package contains data types defined by the OGC Style Layer Descriptor specification.
