24. Information Space WS, Frascati, 3 Apr 2007 Kaiser & Hollingsworth, HALO, 24 Overall Recommendations: GMES Information System GMES will have a diverse user community needing to use products of some or all of the Fast-Track Services and Pilot-Services. To meet its users requirements, GMES must have a modern Information System based on advanced Internet technologies. GMES has no plan for the creation of such a GMES Information System. There is no call for the development of a GMES Information System in the December 2006 FP7 call for proposals. The current call explicitly states that each Fast-track service and Pilot- Service is separately and independently responsible for its own data acquisition and its own product dissemination. The lack of such a system is a critical gap in GMES planning. Recommendation 1: As implied by the forthcoming INSPIRE directive (2004/0175 (COD), C-6 0445/2006, PE-CONS 3685/06), GMES leadership should address the provision of a GMES Information System based on Internet technology.

25. Information Space WS, Frascati, 3 Apr 2007 Kaiser & Hollingsworth, HALO, 25 Overall Recommendations: Infrastructure Candidate Solutions Several candidate technical mechanisms are available to achieve the required data exchanges between the Core Services of the Integrated Projects, without impeding the development of the scientific interactions between the Projects. The WMO Information System (WIS) offers several political and technical advantages. The functionality of the WIS meets the requirements of the Atmosphere and Ocean communities. Interoperability between the WMO and UNESCO / International Ocean Commission data systems has been demonstrated. (E2EDM project) The functionality of the WIS can meet the needs of the Atmosphere and Land Communities, provided the necessary work on interoperability is undertaken. Software development for the European GRID-implementation of the WIS has been funded by the DG/INFO SIMDAT project. The European implementation will be rolled out in 2008.

26. Information Space WS, Frascati, 3 Apr 2007 Kaiser & Hollingsworth, HALO, 26 Overall Recommendations: Potential Collaboration with WMO In the course of the HALO project, WMO extended an invitation to GMES to adapt the WIS system to GMES purposes and to share further development of the WIS for joint purposes. This offer of collaboration should be considered seriously because The WIS architecture and implementation has global reach for meteorology and oceanography. The WIS offers an efficient means for GMES to access WMOs essential meteorological data The WIS is fully consistent with, and offers all the functionality required by, the forthcoming INSPIRE Directive in terms of Metadata Interoperability of spatial datasets and services Network services Data Sharing The GEOSS system is assessing the suitability of the WIS for GEOSS purposes (Achache, WMO Bulletin 2006) Recommendation 2: The GMES leadership should monitor the 2008 roll-out of the WMO Information System in Europe, and assess the adaptability of the WIS for GMES purposes and interoperability with OGC and Earth Science Information Systems.
