Hi Jon,
This is an impressive contribution. :-) It strikes a compromise
between human-readability today and future machine-processability. Are
there particular forms of review or feedback that someone could give you
without spending the kind of time that (I assume) you must have put into
this?
In a 10 minute look-over two questions that occurred to me were:
1. could/should the "water_source" vocabulary be subsumed under
"phenomenon"?
2. wondering whether the "untyped" names might deserve to be treated
a little differently (or at least given a name reflecting their
dignity ;-) ). Many of the members of this group actually seem
like top level semantic concepts (e.g. "derivative of"). Others
seem like mere grammatical artifacts ("and")
