We've been kicking around the the Data Format Controlled Vocabulary
list as well. We had a call with Valerie, Tyler and Scott recently
about inconsistencies in this list. One of the goals of this list
(from ARC team review of our metadata) was to help users understand
the software needed to read/use the data. We suggested to add a
field to this structure whereby values such as "ESRI", "Microsoft",
"QGIS", "Adobe", "Google" etc. could be associated with a format. I
think it would be a good exercise for all the DAACs to generate a
list of formats they use and associated s/w, then bring them
together over some telecons, face to face meetings, and thru
tracking this effort via the Earthdata wiki, to eventually help
generate a more well-thought-out list.<br>
<br>
Thanx..<br>

<p>I'm curious whether the ESIP semantic community has any
opinions on these two controlled vocabularies. <br>
</p>
<p>One question I have is why a measurement keyword list was
necessary when GCMD already has the science keywords (a source
for the original SWEET). i.e. why not integrate measurements
(which are represented as variables in the science keywords)
into the science keywords?</p>
<p><br>
</p>
<p>the data format list is even more perplexing to me. "incidence
angle file" is a format? Georeferenced TIFF in addition to
GeoTIFF? DV? (digital value?) is a format? KML as well as OGC
KML? ASCII and text (what about unicode?) DEM, if this refers to
digital elevation models with a .DEM extension from USGS, are
ASCII files. </p>
<p><br>
</p>
<p>Many formats are subtypes of other formats listed. Wouldn't a
better approach be to list the <i>encodings</i> (a much smaller
list, which would tell users how to read the data with software)
and then add the conventions that have been applied (e.g. CF for
netCDF or GRIB for binary). For the encodings list, why not
start with mime types?<br>
