Center for Environmental Studies Arizona State University Ecological Metadata Language Serve to integrate, rather than dictate, site solutions for data management –ASU, Central Arizona, Naitonal LTER network, OBFS Machine parsable –Based on XML Build on existing standards –FLED, Dublin core, ISO 19115, FGDC

Center for Environmental Studies Arizona State University Xylopia Components Data Collector Input: EML Query Output: Clipped EML & Raw Data or Processed Data (ASCII) Graph Generator Input: Clipped EML & GG Message Output: PNG graph Statistics Calculator Input: Clipped EML & SC Message Output: Clipped EML & Stats (ASCII) Map Generator* Input: EML Query & MG Message Output: JPG, zip, map service configuration *This module is not a web-service Xylopia Server-side Xylopia Client-side Web-based Application (SEINet, Ecology Explorers, ClimDB, etc.) SOAP CES Center for Environmental Studies

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
