Implementation of Web Service Technologies in GFDL's FMS Runtime Environment Y. Malysheva, S. Nikonov, V. Balaji GFDL The 7 th GO-ESSP Workshop September , Seattle, WA September 17 th 2008

Outline  GFDL FMS Runtime Environment (FRE) is a tool that allows scientists to configure and run experiments using XML configuration files.  Curator metadata DB is a centralized metadata storage for entire modeling process, populated automatically from FRE XMLs  The MDB Web Interface uses the Curator DB as the backend to allow scientists to see and interact with the experiment metadata in a user- friendly way  The Analysis web service is a part of the Interface that lets users generate analysis figures from pre-existing data on the fly; they can then view and download the figures through the interface.
