GEOSS 10 Year Reference Document (p. 135) Common Object Request Broker Architecture (CORBA) Web Services Definition Language (WSDL) Electronic Business Extensible Markup Language (ebXML) Unified Modeling Language (UML)

“GEOSS service definitions are to specify precisely the syntax and semantics of all data elements exchanged at the Service interface, and fully describe how systems interact at the interface. At present, the systems interoperating inGEOSS should use any one of four open standard ways to describe service interfaces: CORBA, Common ObjectRequest Broker Architecture; WSDL, Web Services Definition Language; ebXML, electronic business ExtensibleMarkup Language, or UML, Unified Modeling Language.”
