<font face="Times New Roman">Hi,<br>
<br>
A careful preparer of CMIP output will generate a new tracking_id
and record it at the same time as he changes anything in the
header (or elsewhere in the file). So, I agree with Bryan, the
tracking_id is very useful except when the data generator is lazy
and fails to create a new tracking_id. I'll bet that for well
over 99% of the files written, the tracking_id will likely be
reliable (at least much better than 80 - 20). Of course check-sum
tells you absolutely whether 2 files are identical, but it has
limitations too, as pointed out in earlier emails.<br>
<br>
Also, as noted earlier by others, most files that differ but have
the same tracking_id have contain identical data, but have
slightly modified "headers". In most cases this means no matter
which of the files with identical tracking_id's a user uses, one
could reproduce their results, which is mostly what we care about.<br>
<br>
That being said, perhaps, I need to send the modeling groups a
reminder that they should generate a new tracking_id when they
modify their files in any way.<br>
<br>
Oh, and I will try to send out an email this weekend to the
modeling groups urging them to add checksums to their tds catalogs
as soon as possible (i.e., I agree this is essential and high
priority). Besides enabling users and "replicators" to determine
whether they've got the latest version of a file and that it has
been transferred correctly, are there other important reasons for
including the checksum I should articulate in my email?<br>
<br>
Best regards,<br>
Karl<br>

Hi,<br>
<br>
Indeed, that's what I think :-)<br>
Changing the file with anything other than CMOR won't regenerate
the tracking_id, and this happens always when changing the header
only (wrong variable name, wrong grid type, wrong email address)
This different files from different versions to share the same
number.<br>
<br>
BUT!<br>
tracking_id + Checksum is unique and should point to the file in
question (the Checksum alone has no semantic, so it could be
disastrous in the future if we rely on it and use it in a similar
project... we won't be able to tell those files apart even if the
checksum is unique... but that's just my view)<br>

agree and this is a debate that has been waiting in the
wings for some time. I believe Estani doubts the
tracking_id is much use. I'm on the fence -- it is a
record of what the data was when it passed through CMOR

guarantee what data you have though.<o:p></o:p></span></p>

wouldn't rely on tracking_id - there is too high a

just minor updates to the meta-data - hmmm... maybe that
statement was a red rag to a bull). I think the checksum
is the most reliable indicator of the uniqueness of a

CMOR is run. Bryan is right that the tracking_id or md5

datanodes have implemented this. Maybe the wget scripts
need to include versions in a more explicit way than
just the DRS path which would allow datanodes that can't
implement DRS to include versions. It would be good if
wget scripts replicated the DRS directory structure at

<p class="MsoNormal">Well, after 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. <o:p></o:p></p>

<p class="MsoNormal">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! <o:p></o:p></p>

<p class="MsoNormal">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. <o:p></o:p></p>
