2 WSMO Studio – an Integrated Service Environment for WSMO The need for ISE Tool support is crucial for the adoption of a new technology Provide easy to use GUI for various WSMO tasks Working with ontologies Creating WSMO descriptions: goals, services, mediators Creating WSMO centric orchestration and choreography specifications Import (export) from (to) various formats Front-end for ontology and service repositotories Front-end for runtime SWS environments (WSMX) Link to existing WS landscape (WSDL, UDDI, BPEL, WS-Policy,...) Cover the different perspectives of the different users Provide functionality in a way that maximizes users’ productivity (role- oriented development)

3 WSMO Studio – an Integrated Service Environment for WSMO Requirements Modular design Different users need to customise the functionality in a specific way Easier to maintain (e.g. ship new versions and bugfixes) More suitable for 3 rd party contributions Extensibility SWS is an emerging domain It is difficult to specify requirements and functionality affront Tools need to evolve as the domain evolves

4 WSMO Studio – an Integrated Service Environment for WSMO Requirements (2) Architecture based on open standards Lowers the cost of adopting / integrating a tool 3 rd party extensions and improvements are more likely to occur Flexible licensing An Open Source licence improves the adoption rate An OS licence may improve the quality of a tool An OS licence should not collide with proprietary 3 rd party extensions (by being too restrictive / viral)

5 WSMO Studio – an Integrated Service Environment for WSMO WSMO Studio Goals Provide an open architecture and implementation of Integrated Service Environment for WSMO Java based implementation Open Source core (LGPL) 3 rd party contributors are free to choose their respective licensing terms Modular design an Eclipse based plug-in architecture Extensible 3 rd parties may contribute new functionality (plug-ins) … or extend / modify existing functionality

6 WSMO Studio – an Integrated Service Environment for WSMO WSMO Studio (2) Present status Developed within EU funded DIP and InfraWebs projects First stable release – 15 Jun Limited functionality Serve as a guideline for 3 rd parties that would contribute plug-ins Next releases will add new functionality Development releases + sources already available

7 WSMO Studio – an Integrated Service Environment for WSMO WSMO Studio (3) Architecture (initial set of plug-ins) WSMO Studio runtime Provides functionality common across all plug-ins based on wsmo4j Ontology plug-in Ontology perspective NOT intended to be a Yet Another Ontology Editor WSMO plug-in WSMO elements: goals, services, mediators Repository plug-in Front-end to ontology and service / goal repositories Usage Standalone application (customised) Integrated into an existing Eclipse deployment
