Telecom and Informatics WFS and Web Services WFS does not use WSDL and SOAP Unclear Business Model Who will provide WFS-clients? Who will provide WFS-services? Who will provide Registry-services? WMS v1.1.1 with chaining to WFS is promising How do we compose and integrate WFS with std WS? How will WFS evolve?

Telecom and Informatics ACE-GIS IST Adaptable and Composable E-Commerce and Geographic Information Services Duration: June September 2004 Budget: 3,7’ Euro Goal Provide better and more efficient tools for the development, deployment, discovery and composability (composition) of distributed web-services with special emphasis on the key combination of geographic information and e-commerce services.

Telecom and Informatics GO-1 Technology View – Abstract (Multi-Platform) Interface Specification 1. Produce an Abstract Service Interface Specification for all GO-1 objects (Application Objects, Information Objects and Service Objects) from which multiple implementation profiles could be derived for specific target platforms. 2. Specify, build and test a Java Implementation Profile as derived from the GO-1 Abstract Service Interface Specification.

Telecom and Informatics Summary WFS is an important component in a geospatial environment but not quite mainstream Web Service Need to demonstrate applications, servers and registries integrated with security, payment costs, gain experience ease of use, easy implementation more functionality!!!! ACE-GIS provides Model-driven development tools GO-1 provides standard models and more application functionality
