you for all the information provided below. I get back to you
with another question regarding COD. In the framework of our
project aiming at building up a data repository selection tool
for reasearchers, I would like to know if COD ID has the same
features and role as a DOI. In other terms, does it act a
permanent identifier that can be cited and accessed even if
the URL changes?</span></p>

<p>Yes, indeed, the COD IDs are stable permanent IDs. Even when the
data are no longer available (e.g. the structure is retracted),
the ID stays and the metadata are further available. The COD IDs
function as any other permanent IDs required to identify a data
record, e.g. Archival Resource Keys (ARK), Handle identifiers,
URNs; and, yes, DOIs are in the same category (except that you
need to pay money to get DOIs assigned :/ ).</p>
<p>In addition to that, COD URLs (which are actually URIs) of the
form '<a class="moz-txt-link-freetext" href="https://www.crystallography.net/cod/2000000.html">https://www.crystallography.net/cod/2000000.html</a>' or
'<a class="moz-txt-link-freetext" href="https://www.crystallography.net/cod/2000000.cif'are">https://www.crystallography.net/cod/2000000.cif'are</a> intended to
remain stable into the future and can be used as COD structure
identifiers.<br>

<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Regarding
my previous question related to licenses, the idea was not to
promote copyright but rather to ensure that structures can be
freely reused and cited using for instance CCBY license
instead of depending on the license of the paper in which the
structure is described (which often entails copyright rules
applied by publishers.)<o:p></o:p></span></p>

<p>Well, this was discussed in the COD AB, and the current collegial
decision is to put CC0 in the COD.</p>
<p>If you feel very strong about the issue, you can submit a "COD
Improvement Proposal" to the COD AB (or to the cod-bugs@ list),
and I'll forward it to the COD AB and promise to organise an
on-line discussion (you would be welcome to participate in it).</p>
<p>We need to take into account that CC-BY is more restrictive for
data users than CC0, so we need to look carefully as to not
jeopardise their work flows. Most (all?) of our users, however,
already now cite the original works since this is the custom in
the academic community, so CC-BY might be not that disruptive
after all.</p>
