| Abstract | The important problem of the integration of cross-organizational geo-spatial services is the various implementations of a service platform. The platforms can be W3C SOAP web service, OGC web services, and REST web service. Services which have different interfaces are the constraint that limits the use of the most popular orchestration technology such as BPEL for assembling those heterogeneous services. In this thesis, the three mandatory models (i.e., the heterogeneous geo-spatial services coordination model, the heterogeneous-payloads manipulation model, and the heterogeneous-exception handling model) for a new language implementation which provide a cross-platform orchestration are identified and addressed. The language interpreter/executor so called orchestration engine is implemented for the testing and demonstration of a language. The three workflow scenarios (i.e., site selection, coordinate transformation, and network analysis) are defined for a language testing. The heterogeneous on geo-spatial services coordination, payloads manipulation, and exception handling are tested. The result of each scenario demonstrated the successful of a cross-platforms orchestration, and proofed the three proposed models are the essential elements of a cross-platforms ability. |
