6. Ecological Data Archives • Diversity in formats, schema, size, organization. • Tabular – SQL, ASCII, App formats • GIS – shapefiles, SDE, coverages • Raster – raw, SDE, Remote sensing, Erdas, ESRI Grid • Standards and procedures may exist within individual archives • Few standards at network level Center for Environmental Studies Arizona State University

7. 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

8. EML 2.0 Design • Modular, with classes relating to specific functional roles • Uses XML Schema complex types to define extensible base classes of information resources • Extensible via the linking of new modules within the schema • Organized to abstract the logical description of data from the physical Center for Environmental Studies Arizona State University

16. CES Center for Environmental Studies Xylopia: Metadata Mediate Access A web-service (Apache SOAP) based data analysis application for EML • Uses EML Metadata to resolve message content • Modules for: • Data Query • Processing • Visualization • Analysis Center for Environmental Studies Arizona State University

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

18. CES Center for Environmental Studies 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 Center for Environmental Studies Arizona State University
