The cycle is completed as these Products and Services get taken up by WGISS into the WGISS Menu. A Proposed WGISS Test Environment Version Sept 12, 2000 WGISS Data & Information Products 1 • A Nakodo process will allow the creation of a WGISS Test Facility for the projects. • An improved set of Products and Services should be one result of this process. • Projects and the WTF also have links to the “outside”. E.g. WTF can be deployed for long term operation. • The Test Facility can use Products and Services from the WGISS Menu and from the Projects. And can feed back to the Projects! • These are being collected into a “WGISS Menu” which will offer a single place to find them. • There is a set of tools and services (e.g. IDN, DIAL) • A partnership of programs/projects will be able to draw from this menu Agglomeration oftools and servicesheld and operated by CEOSorganisations 2 3 WGISS Menu 4 Improved Products & Services Products & services Open reference list of WGISS products & services, updated on the basis of the results of the test facility, linkedon-line to the products and servicesthemselves 5 Based on the test facilityresults 6 7 Links to data suppliers Products & services 8 Disaster Management Disaster Management 9 Oceans Oceans GOFC GOFC Partnership WGISS Test Facility Projects Selected WGISS products made into a coherent, open, modular system by the partners to address each project’s needs (can include tools dev’d by the project), dev’d & tested against the project’srequirements Nakodo Define the data & information systems and services requirements Tools, data Products& services Non-WGISS requirements Long term operation A Proposed WGISS Test EnvironmentVersion Sept 12, 2000

Issues • How to decide which interfaces & components to address first • How to initially reuse items that are currently in the WGISS Menu? • How to develop an interoperable services infrastructure • How to hook in existing and new analysis tools (e.g. IDL) • How to identify and define interfaces that will enable systems to interoperate • How to arrive at the right level of abstraction for interfaces • How to develop interfaces that enable plug and play components • How to define and develop components that will fit into or extend current systems • Can current systems be extended to include the additional data services without a major redesign? • Can the new components add functionality but minimize cost of development and maintenance? • How to define and develop interfaces, components, and toolkits that will allow quick building of new portals and user group specific systems • How to facilitate vendor participation in the interface specification and component development process • Should we aim for programmatic API access to services vs. "portal" access for end-users?
