Hi Sébastien,<br>
<br>
This is a known problem about replicas. I'm removing all replicas
from our system (just from the Gateway) hoping this will get
solved. This shoudn't inhibit replication via the BDM, but it will
forbid discovery... Anyway, I was waiting/hoping for a solution to
this, but I see no other option as to retreat them. Should be
ready soon...<br>
<br>

<br>
Ok, thanks for letting me know. What about PCMDI
replicated/published datasets?<br>
<br>
<blockquote cite="mid:4F1D4746.9030609@dkrz.de" type="cite">
Regarding your last point:<br>
> Can you confirm that *not* all users authorised to publish at
DKRZ are able to modify this dataset? <br>
<br>
Well indeed they can, since there's only one person authorized to
published to DKRZ (me) and only one person able to change that
authorization (myself) I don't think this is a problem... </blockquote>
<br>
Ok, that was my supposition. If it's only you then no problem. In
the future it could be that other users can publish to the DKRZ
gateway. By that time it would be good to change permissions (just
to avoid mistakes).<br>
<br>
<blockquote cite="mid:4F1D4746.9030609@dkrz.de" type="cite">I guess
your question goes more on why am I able to "write" IPSL dataset.
Well, please remember that we are talking about replicas, so I
can't alter IPSL dataset, but I can publish a replica.
Furthermore, I'm even able to publish wrong information, i.e.
another datasets or a corrupt one, and mark it as a replica of
IPSLs. This is something we don't really want to happen.<br>
</blockquote>
<br>
Again it's a matter of trust. I'm sure you perform all the necessary
checks to avoid publication of corrupted replicas.<br>
<br>
<blockquote cite="mid:4F1D4746.9030609@dkrz.de" type="cite"> On the
other hand, IPSL may remove, alter or do whatever it likes with
the "original", and that's again something archives don't want, at
least not if "our" copy is treated as the "replica".<br>
<br>
</blockquote>
<br>
Up to know we preserve datasets version and we follow the CMIP5
procedures precisely. The benefit for you is that you have time to
define the best replicas/publication strategy.<br>
<br>
<blockquote cite="mid:4F1D4746.9030609@dkrz.de" type="cite"> We do
have a lot to define regarding replicas. This is an ongoing
conversation, so I'll kindly ask or stakeholders to speak their
mind.<br>
</blockquote>
<br>
I believe gateways should expose all dataset version (especially the
last one). <br>
<br>
Because it's taking time to replicate/publish it would then mean
that the latest version may not have been replicated but should
appear as such in gateways.<br>
<br>
It would also mean that the best thing the replication software must
achieve is to be able to download only what has changed (based on
checksums when available) and following the drslib strategy to build
link when nothing has changed.<br>
<br>
Thanks.<br>

<br>
browsing gateways from PCMDI, BADC and DKRZ using the underlying
facets of this dataset I observed a strange behaviour.
cmip5.output1.IPSL.IPSL-CM5A-LR.piControl.mon.ocean.Omon.r1i1p1
<br>
<br>
This dataset have 2 versions, v20110324 and v20111010. <br>
<br>
Only the BADC gateway display the latest version. The other two
gateways display the old one and never mentioned the existence
of a new version. I believe this is a major issue due to
replication side effects. <br>
<br>
Because there isn't any "version" facet it would be important to
make visible every version of a dataset in an homogeneous ways
across gateways? <br>

<br>
<br>
Also selecting the administration tab from the DKRZ gateway I
can read the following: <br>
Groups authorized for Writing: Users authorized to publish at
DKRZ <br>
Gateway Administrators <br>
<br>
Can you confirm that *not* all users authorised to publish at
DKRZ are able to modify this dataset? <br>
<br>
