<p>Hi John,</p>
<p><br>
</p>
<p>I agree, it would be good to have the DAACs compile their list of
formats. Ideally, there would be a shared spreadsheet, where each
DAAC would check against what was already there, to avoid have the
same format called different things.</p>
<p><br>
</p>
<p>I've taken the GCMD list and assigned encodings to all that I
could identify. The categories are ASCII, Binary, Image, Library
(i.e. associated with a software library like HDF), and
Proprietary (which is somewhat of a mixed bag, could be ASCII or
Binary, open or closed).</p>
<p><br>
</p>
<p>The spreadsheet is here:

<p>Feedback, corrections, additions welcome. I'll give edit
permission as requested. </p>
<p><br>
</p>
<p>Cheers,</p>

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>
