Workshop

  • Peter: be definitive about plans, can always change them later
  • Peter: be succinct
  • Upload to wiki by end of week
  • Ilkay: use "oceanographers and terrestrial ecologists"
  • TODO: Mark, Peter, Eric to finalize the invite list
  • Ilkay: should have someone from ROADNet -- Vernon? -- for the workshop

Sensor purchases

  • need to make decision on Crossbow motes versus NI CompactRIO
    • Crossbows can be pretty flakey
      • Sevilletta LTER has had problems with them
  • EricG: Onset might be a better option
  • TODO: EricG to send info on datalogger options to Eric S and Matt

Development update

  • Ilkay
    • Looking into RBNB and Antelope docs to determine the access API
    • Been working on a Kepler stream actor to get RBNB from NEON stream testbed
    • Aiming for NEON TDR meeting on April 29
      • Adapting code from Peter Shin @ NEON that had been used for storing data in relational db

  • Nathan
    • data models seem compatible -- looked at the Ptolemy model and there's a reasonable mapping between the types
      • fixed point type probably maps to a float
    • sequence is an ongoing problem
    • have to map grids, but will lose implied semantic information
      • grid is collection of arrays, main array with other arrays that specify, e.g., coordinates in lat and lon
      • need to try to maintain the implied relationship between these 3 arrays to ease processing
    • hasn't figured out how to implement an actor
    • also need to map Common Data Model (CDM) and EML
