One aspect that may be missed in the WaterML 2 / WDTF and the ACORN-SAT comparison:

- WaterML is a community agreed semantic representation of that domain's data. Using it organisations can exchange data and be 'fairly' comfortable that they are sharing the same concepts.

- ACORN-SAT is a representation of an internal file format used by one team, within one organisation.

We need to find a way to adequately support the community agreed representations of a domain's data for true interoperability.  

I expect that the community agreed representations will mature as they get real world usage. So if they are 'ugly' now, it doesn't mean that this will always be so.

Bill, this was something Kerry talked about way back at the workshop.
See her paper at [1] and my over-simplified reportage at [2].
