<div style="background-color:#FFFFFF">
<p style="margin-top: 0px; margin-bottom: 0px;">I'm curious whether the ESIP semantic community has any opinions on these two controlled vocabularies.
<br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;">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 style="margin-top: 0px; margin-bottom: 0px;"><br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;">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 style="margin-top: 0px; margin-bottom: 0px;"><br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;">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>
