Hmmm, interesting point, Rich. The ACDD and OceanSITES conventions both
extend
CF, and both recommend a comma separated list in the Conventions attribute.
There doesn't seem to be an explicit prohibition in the document against
using commas
for extensions of other conventions. It seems to me
The Unidata recommendations at
(http://www.unidata.ucar.edu/software/netcdf/conventions.html) made
sense to me:
If your conventions are hierarchical (general followed by more
specialized) use the '/'.
or
If your conventions are not hierarchical, use the ',' (or space).
But I suppose you are
David,
I looked at this a bit and I'm not sure that
http://cf-trac.llnl.gov/trac/ticket/76 actually captures this need, as
UGRID is intended to *extend* CF, rather than a stand-alone
alternative.
For situations like CF and UGRID, which *extends* CF, it would appear
from this guidance
Hi Jim,
Section 7.1 of the CF Conventions doesn't say it directly, but it
does state that contiguous cell boundaries are described by the
upper bound of one cell being equal to the lower bound of the next
cell. This implies that the upper bound is exclusive.
I'm not sure about this
David,
I was using upper and lower in a notional sense, and you are right that
coordinates can be monotonically increasing or decreasing. To be
completely general, I guess I would need to refer to first and second
bounds. So the first bound of cell j is inclusive and the second bound
of cell
