See the file (http://capita.wustl.edu/capita/capitareports/080701_EPA_Interop/080702_DataSummitDS.ppt ) concerning “data use through federation”. This concept was discussed extensively by Rudy Husar. Other subjects discussed include:

  • Inclusion of ozone and precusors in VIEWS as a demonstration of interoperability; it would be good to place data in VIEWS that can take advantage of visualization tools and distributed access.
  • “It is best to do things where it is best to do them.”
  • The need for a framework for negotiation between computers; it might be best for users if they could get aggregated data that has been “EPA sanctioned”.
  • Use of “browse images/data” that provide a “light-weight” approach to exploring at a high level, e.g., GoogleEarth.
  • Where to store versus where to process data; generally it is better to store raw data locally in order to facilitate processing; interoperability options should be explored and decisions made early.
  • The concept of a “wrapper” is important.
  • Development of the data exchange standard by Domenico.
  • The need for an ad hoc group concerned with earth science to address data standards, e.g. satellite data, and access to raw data through a federated system.
