Hi,<br>
<br>
I'm changing the subject so we get back on course :-)<br>
<br>
Indeed URL *will* change, *but* they contain more information that
the filename and you can easily get to the subset of filename +
checksum (just use basename on the url from any UNIX machine).<br>
<br>
Furthermore you could *know* from which server you got the data (a
replica, the original, etc).<br>
<br>
That's why I think the simples is to store just the script or
whatever url list the user got.<br>
As I said, the checksum is enough to identify the file, but people
might also want to find what happened with it... and the extra
information might provide the required clues.<br>
<br>
But yes, as Stephen pointed out there are multiple use cases, I was
thinking about the user. From the server side you could indeed have
"dataset + set(file_name, file_checksum)" as a representation of
that dataset that will be the same for all replicas. I'm missing the
point though, why would you want to do that? Citation? Storage? a
notification service? The URL *should* be:<br>
https?://<host_name>/<service_root>/*DRS_PATH*/*DRS_filename*<br>
<br>
so DRS_PATH (=dataset + version) + DRS_filename + checksum is what
you are proposing. I do think it's enough.<br>
<br>

Estani<br>

<p class="MsoNormal">Hi,<br>
<br>
the Tracking_id is generated by cmor, so if the files are
re-concatenated using any other tool (e.g. cdo) then it
should be left as is. This has the benefit of not altering
the checksum and thus marking the file as it is. So
basically a renaming should trigger a new version but should
not alter the files in any other way (i.e. same checksum).<br>
<br>
And indeed Stephen, the checksums alone are "enough" but
it's not practical for any other purposes (until we have a
service to reverse search to files).<br>
I would say URL + checksum is enough information (that's
more than the filename). The filename alone it's ok, but you
will have to look for the dataset version...<br>
<br>
So either dataset_id + version + file_name + checksum or url
+ checksum, which is the general case of the former.<br>
<br>
Url + checksum is already being stored in the wget script,
so that file would be the key for citing/finding files.<br>
My advice: store it together with the data (which I know
most people are doing already). <br>
<br>
...I'm already changing the subject of this thread... sorry
for that.<br>
<br>
Thanks,<br>

matters for CMIP5 aside, I've been thinking about how we
could create an unambiguous manifest of a
dataset-version. I.e. containing enough information to
uniquely identify it's contents without any extraneous
information that might change with dataset location,
available services, etc. . I came to the conclusion
there are 2 possible solutions: either a it's a sorted
list of (filename, checksum) pairs or it's just a sorted
list of checksums. The difference is whether filenames
are "part of the dataset". My instinct is that you can't
decouple filenames from the dataset. Users expect
filenames to be meaningful and in some contexts
information inside files could refer to filenames within
the dataset (e.g. gridspec files). This is how every
other contents-based versioning/packaging system I know of
works: git, BagIt, BitTorrent</span><o:p></o:p></p>

<p class="MsoNormal">Hi,<br>
<br>
it's required a new version to be published, so that its
publication will signal that something has changed. If
not, then it won't be picked up by other services, e.g.
replica services, as it would assume the data hasn't been
changed at all.<br>
In our particular case (DKRZ) we will see files haven't
been changed, provided that the checksums are properly
published, and will just link them to the older ones,
allowing users to get both versions (i.e. users that are
already downloading files will be able to keep downloading
them, and not have to start everything anew because of
this renaming)<br>
(I can't see if the checksums are there because the node
is not accessible at this time)<br>
<br>
We could use that information to infer what happened and
display it under the history information.<br>
<br>
Maintaining the same version provides no benefit for the
publisher at all and creates the same confusion to the
user (which will see that files are missing).<br>
<br>
Just my 2c,<br>
Estani<br>

Quick answer on my way to a meeting - CMOR2
was used for this and at least one other
dataset that we have (from COLA) that also has
the yyyymmdd format. I'll ask a few other
questions after my meeting but that's the
short answer.<br>

I'm copying a contact for the GEOS-5 model who
may be able to provide some information on
this. I can't explain why the monthly file
names are inconsistent with what CMOR2 puts
out. Maybe CMOR2 wasn't used. The DRS
document doesn't absolutely forbid including
more precision than necessary in specifying
the time-periods, so I don't think we can
force them to rename their files. That being
said, my hope was everyone would use CMOR, so
the file names would all follow the same
template.<br>
