Center for Environmental Studies Arizona State University Typical Xylopia Workflow  EML Query message built by the app/user  App sends the message to the Data Collector  Data Collector finds the data, puts it into an ascii file and places the data and a new ‘clipped eml’ into a designated drop box  App gets these data and displays it to the user  If the user requests a graph or statistics on these data, the ‘clipped eml’ and ascii file is usually used by these web services  If the user requests mapping data, the Data Collector’s output varies depending on the requested file’s format CES Center for Environmental Studies
