Global Organization for Earth System Science Portals (GO-ESSP) 2008 Workshop
GO-ESSP 2008 Workshop – Technical Themes
Presentations should be responsive to one or more of the following technical themes -- the areas of emphasis at this year’s meeting. Connecting these themes to the specific needs established by international bodies that coordinate climate and weather research activities (e.g. IPCC WG1 assessments, WMO, COPES, GEOSS) is encouraged.
The emergence of distributed, federated systems for climate and weather offers substantial promise for accelerating the progress of science. Current examples include TIGGE, the WMO WIS initiative, and GEOSS. Presentations in this theme area may address broad development efforts in the area of federated systems, such as those just mentioned, and/or specific developments or technologies that relate, such as federated identity, authentication, authorization, data access, catalogs, metadata, and knowledge.
Web services for scientific data systems
Contributions to this theme will describe experiences building and/or deploying services which expose data to either human users or software agents. Such services could include, but are not limited to, TDS, OpenDAP, OGC WxS and newer alternatives based on REST and/or KML. Of particular interest are services which consume data from other services (as, for example, a regridding service might do).
Semantically enabled environments
It is increasingly the case that model providers participate in multiple different and independently coordinated international campaigns, with each, in principle, having their own governance and metadata requirements. While it would be desirable for metadata standards to be coordinated across campaigns, it is often not practical. Current advances in technologies for semantic mediation make it possible to make the same underlying data adapt to evolving metadata requirements. These technologies rely on environments that allow matching of terms, and bundles of terms, across different vocabularies, and deliver data compliant with those vocabularies upon request. This theme will address the current state of the art in the field of semantic mediation, and the small but growing list of applications in the field of Earth System Science.
New strategies and technologies for web-based user interface development.
Recent improvements in the functionality, control and level of standardization of Web Browsers and asynchronous communications between browsers and Web servers have made it possible to develop User Interfaces for the Web that rival the quality of desktop applications. This is creating new opportunities for community-wide sharing and analysis of climate-related data. In this session we will explore some of the new toolkits, programming paradigms and tricks that are advancing this revolution in Web-based user interfaces (as well as the pitfalls).
- Server-side support, debugging and development environments -- Firebug, Eclipse, the Google Web Toolkit
Climate and Forecast (CF) conventions
As in past years, Friday of the GO-ESSP meeting (˝ day) will be devoted to CF issues. Both technical issues, such as extensions to CF to better address satellite data, unstructured mesh data, and collections of observations; and organizational/governance issues are welcome topics. In particular topics of pressing interest include
- Identifying a maintainable growth path for CF standard names
- CF conventions in the context of other standards (ISO, OGC, etc.)
- CF extensions needed to address AR5 climate models
- libCF status and netCDF 4.x
- CF compliance: what it means?; how to test?
- Increasing the semantic richness of CF standard names
