Compare with ncml approach by ouranos

[cehbrecht]

Ouranos is using ncml to provide data fixes.

Point @huard to an example where ncml does not cover the needed fix.

A fix currently looks like this:
https://github.com/roocs/proto-lib-34e/blob/master/fixes/cmip5.output1.INM.inmcm4.rcp45.mon.ocean.Omon.r1i1p1.latest.zostoga.json

Could our scanner also generate ncml fixes need by ouranos? So the scanner could be a shared component.

Currently this is all prototyping ...

Would something like this work for this particular example ?

<variable name="tas">
  <logicalReduce dimNames="lev" />
</variable>

Looks nice and simple @huard

In theory, yes. Unclear yet to me how this plays out in practice. I've still not figured out how to design code that parses an XML and translates that in xarray commands. I'm concerned that without a clear design, this is going to turn into a mess.
