Hi Jennifer,<br>
<br>
I'm still not sure how is Lucas change in the API going to help you
Jennifer. But perhaps it would help me to fully understand your
requirement as well as your use of wget when using the FTP
protocol.<br>
<br>
I presume what you want is to crawl the archive and get file from a
specific directory structure?<br>
Maybe it would be better if you just describe briefly the procedure
you've been using for getting the CMIP3 data so we can see what
could be done for CMIP5.<br>
<br>
How did you find out which data was interesting?<br>
How did you find out which files were required to be downloaded?<br>
How did you tell wget to download those files?<br>
<br>
We might have already some way of achieving what you want, if we
knew exactly what that is.<br>
<br>
I guess my proposal of issuing:<br>
bash <(wget <a class="moz-txt-link-freetext"
href="http://p2pnode/wgetscript?experiment=decadal1960&realm=atmos&time_frequency=month&variable=clt">http://p2pnode/wget?experiment=decadal1960&realm=atmos&time_frequency=month&variable=clt</a>
-qO - | grep -v HadCM3)<br>
<br>
was not acceptable to you. But I still don't know exactly why. <br>
It would really help to know what you meant by "elegant use of wget".<br>
<br>
Thanks,<br>
Estani<br>

working from the client side to get CMIP3 and CMIP5
data, I can say that wget is a fine tool to rely on at the
core of the workflow. Unfortunately, the step up in
complexity from CMIP3 to CMIP5 and the switch from FTP to
HTTP trashed the elegant use of wget. No amount of
customized wrapper software, browser interfaces, or
pre-packaged tools like DML fixes that problem.

<div>At the moment, the burden on the user is
embarrassingly high. It's so easy to suggest that the
user should "filter to remove what is not required" from
a downloaded script, but the actual pratice of doing
that in a timely and automated and distributed way is
NOT simple! And if the solution to my problem of filling
in the gaps in my incomplete collection is to go back to
clicking in my browser and do the whole thing over again
but make my filters smarter by looking for what's
already been acquired or what has a new version number …
this is unacceptable. The filtering must be a
server-side responsibility and the interface must be
accessible by automated scripts. Make it so! </div>
<div><br>
</div>
<div>By the way, the version number is a piece of metadata
that is not in the downloaded files or the gateway's
search criteria. It appears in the wget script as part
of the path in the file's http location, but the path is
not preserved after the wget is complete, so it is
effectively lost after the download is done. I guess the
file's date stamp would be the only way to know if the
version number of the data file in question has been
changed, but I'm not going to write that check into my
filtering scripts. </div>
