AbstractAbstractThe European project ACE-GIS (Adaptable and Composable GIS and E-Commerce services) addresses a Model Driven Architecture approach to the specification and development of semantic interoperable services for Crisis Management and Environmental planning systems. The methodology and tool-support for service-oriented architecture specification is provided by the COMBINE project (Component-Based Interoperable Enterprise system development), with enhancements for model-based composition, using UML activity diagrams and mappings to BPEL4WS/BPML. The underlying standard services are based on the OGC Open Web Services for GIS components, and on a Web service infrastructurewith extended ebXML Registry/Repository support.

OGC – GO-1 – Geospatial Objects InitiativeFebruary 2003 – June 2003

OGC – GO-1 – Geospatial Objects InitiativeFebruary 2003 – June 2003

• Develop a set of standard objects for the development of applications using geographic data

• Develop an architecture for distributed geographic processing that is independent of the implementation platform

• Develop processes to generate implementation platform specific profiles of the abstract architecture

• Validate that the architecture and profiling processes can be used to create working implementations

• Trying out MDA principles for Web services and Java

Advantages with a model-driven approachAdvantages with a model-driven approach

• Always up-to-date UML models documenting the underlying platform realisations

• Easier to read and understand UML models than XML Schema

• Technology changes, conceptual models stay the same• The same UML model may be used to generate multiple

output formats (ISO 19118, GML, XMI, Web Services, CORBA, ebXML, DCOM, J2EE, C++…)


ConclusionConclusion

• Tool and methodology support is emerging (ref. COMBINE ++)• Further needs:• Well defined rules and tools for creating platform-independent

service and information models• Well defined rules and tools for mappings to platform-specific

models for the most important platforms: Web services/XML, CORBA, J2EE/EJB, SQL, ...

• A version of XMI (2.0?) that can produce human readable (HUTN) XML – similar to the handcreated XML schema specifications currently being made – (necessary to be accepted in the ”XML” communities)

• A tool-independent model diagram interchange format that can be used to support interoperability between multiple UML tools (thediagram interchange RFP! + more consistent XMI implementations)

• Composable security services – to support composable Crisis management and GI services

The OMG MDA approach is suitable for the specification of servicesand information models for multiple platforms, including web services
