The Living With a Star program at NASA is well underway. In five years, a fully functional, cost-effective system must be in place for acquiring and analyzing the torrent of SDO data, and for integrating them with other SEC missions. The LWS Science Architecture Team has identified this as “… a critical management challenge for the LWS program...” (August 2001). With the anticipated launch date of SDO in August 2007, the system architecture needs to be well defined at the time that the science teams start detailed development of their data processing systems in 2005/6.
We are creating a test-bed system to do just this based upon the prototype, distributed data system architecture developed under the “Problem-Solving Environment for Living with a Star” LWS project; merging this system with the best attributes of the aligned efforts towards the Virtual Solar Observatory prototype and the European Grid of Solar Observations test-bed, and exploiting recent SolarSoft application development, to create the Collaborative Sun Earth Connector (CoSEC) for LWS. Our coordinated effort among these three teams will quickly bring a large fraction of solar data into the LWS community and create a cost-effective environment for assimilating data from LWS and related SEC spacecraft.
Here we demonstrate how CoSEC integrates data analysis of Solar, Heliospheric and MagnetosphericTransients.
CoSEC Service RegistrationWe define a service and datatype ontology to help in defining and coordinating services. Currently these are relevant primarily to SolarSoft, but others can easily be added. Here are the steps to registering a service:1. Define CoSEC name2. Identify service URL3. Provide description for user4. Select CoSEC service type from Service Ontology5.
