Notes on the GE IE discussion

• WaterML 2

• Timelines
  • June 14 deadline (OGC TC meeting) for WaterML2 beta
  • To be available to GW IE ~4 weeks before

• Timeseries
  • Need instruction from P.Tayor on how to vary precision of date/time datatype in result (e.g. just day, month, other range, etc.)
  • Agreed to remove 'Anyscalar' datatype as result of timeseries observation, and create subclasses for different scalar types

• Sampling/sampled feature
  • Issue: cannot uniquely link an observation to a particular sampled feature, because the intermediary sampling feature can be linked to multiple sampled features---tbd by the design group
  • Encoding of the feature: should it be by reference or in line?
    • tentative decision: do both within IE as part of the experiment. Inline (current) for June and both for December. URIs for the link to be a WFS call.
  • WaterML 2 featureOfInterest will be a samplingFeature
  • Should depth features such as water well screens be samplingFeature?
  • We might need to add a singled value time series.
  • Need to add accuracy code to result data structure
  • If we are to stand up a catalog, we need WaterML2 to be able to express the kind of result types

• Other
• Services
  • What all needs to be in place?

• getCapabilities?
  • Need to make a change request. Pete Taylor will look at and distribute.

• describeSensor?
  • boyan and eric will draw up conceptual model of sensor, sampling feature, sampled feature, method (procedure)

• specimen and filters
  • issues with sos re: specimen model of O&M

• R&D: Look at describeObservation.

• Clients
  • Focussed testing from June to December.
  • Need to come up with client test (edge) cases. (Nate)
