13. WGISS-26, Boulder Colorado, USA Sep. 22-26, 2008 13 Highlights and recommendations from IG’s IDN – Recommendations  Continue to provide high-quality Earth science metadata, and active contributors to keyword development, standards definitions and the semantic web  Work towards greater inclusion of NASA datasets  Extend metadata holdings to include popular datasets such as climate change indicators  Continue to promote the GCMD “Brand” through papers, posters etc  Encourage the creation of provider-maintained metadata, exploiting DocBuilder and web interface enhancements  Continue to develop Strategic Plan

14. WGISS-26, Boulder Colorado, USA Sep. 22-26, 2008 14 Highlights and recommendations from IG’s Web Services – Highlight  Established after WGISS-25, The Web Services Interest Group held its first meeting at WGISS-26, detailed the purpose of Web Services Interest Group  Several presentations were made regarding strategies, plans and lessons-learned with using OGC and other Web Services  Layout a good guidance to a Web services-based SOA through USGS/EROS activities related to the re- architecting and redesigning Earth Explorer and GloVis, such approach could create a new baseline for future capabilities  Interest Group members also discussed ideas for continuing to engage in technical exchanges via telecons and other forums throughout the coming year

15. WGISS-26, Boulder Colorado, USA Sep. 22-26, 2008 15 Highlights and recommendations from IG’s Web Services – Summary and Recommendations  Continue with plans to evolve EE and GloVis into SOA, Web services architecture  Collaborate with CEOS and US GEO interoperability efforts  Initiate investigations into performance mitigation approaches and solutions  Pursue prototypes to more deeply explore Web Service implementation and performance issues and feasibility  Web Services are a part of the future

16. WGISS-26, Boulder Colorado, USA Sep. 22-26, 2008 16 Highlights and recommendations from IG’s Data Services  Under consideration and discussed individuals  It should be service-oriented and concentrated on how to provide long term or sustainable data services  It may an important potential services to provide data assistance to WGISS activities  Call for CEOS agencies participations and ideas to layout its objects, forms and activities

17. WGISS-26, Boulder Colorado, USA Sep. 22-26, 2008 17 Technical issues and questions Based on the requirements from GEO, Most activities are mixed technical issues and projects recently What should be the object of IG’s?  Technical-oriented? Projected-oriented? What is the core technologies of GEOSS and how to make our contribution to GEO ?  Registry  Clearinghouse  Portal  Interoperability  …… WGISS owned many technologies but how to make it become whole set to support a dedicated system or application

18. WGISS-26, Boulder Colorado, USA Sep. 22-26, 2008 18 Recommendations from Technical point of view How to identify WGISS IGs ?  Project-Oriented technology IG Promote the applications of new technologies in the project Concentrated on the solutions of technical problems  Technology-Driven project IG Promote the applications of new technologies in the project Concentrated on the application of mixed technologies
