Meeting notes

Model overview

- Upper/lower limits. May crossover with the range values?

- Define specifc range values. Create a tighter connection between the range values and the coversions. Two ways: an explicit relationship to conversion and the ability to transfer separately.

- Units of measure for the parameters; should they be represented within the conversion class? currently down in the IV/DV table tuple.

- Capturing the description of parameters. Need to be consistent with part 1. May use the same local dictionary for params?

- Transition period. Put Paul's document up on wiki. Model the approach both ways. Email on preferences.

- Range values: water quality thresholds, other approaches -- more complex thresholds. May have an algorithm for the values of the range type. Work on list of common types.

- What does the MP actually represent? E.g. mutliple flow series at locations close

- Do we need reason for inclusion/exclusion of gaugings? Could be a second pass on this. GW: could be an extension class from a general process class.

- Show example of usage. How does it relate to the phenomenon types?

- 3d ratings out of scope for first pass; may daisy chain.

- UML model setup to list and wiki.

Next steps

- Presenation to Redlands TC at the HydroDWG session on the 16th Jan: http://www.opengeospatial.org/event/1301tcagenda. We will forward around the draft presentation.
