Hi Markus , Hi Dal & Dm members , <br>
<br>
The obs_id column in Obscore is <b>mandatory</b> , and the idea was
to be able to trace from which observation a data product comes
from.<br>
<br>
So if validators do not check this value , i.e , allow it not to be
filled , or to be filled by NULL<br>
we need to consider the various cases why this information is not
given .<br>
<br>
What does it mean to fill obs_id with NULL? <br>
? i do not know where it comes from? <br>
? the data product I serve here is the raw observation ? <br>
other cases ? <br>
<br>
May be archive designers , providers can clarify this ? <br>
<br>
my 2c , Mireille<br>

[followups again suggested to DAL only]
Given that the discussion on the non-NULL requirement on obscore's
obs_id column did not show a convincing need for the requirement and
it is an implementation burden in particular in the presence of
validators (see the erratum's rationale), I've written up a proposed
erratum for Obscore 1.1; see
<a class="moz-txt-link-freetext" href="https://wiki.ivoa.net/twiki/bin/view/IVOA/ObsCore-1_1-Erratum-3">https://wiki.ivoa.net/twiki/bin/view/IVOA/ObsCore-1_1-Erratum-3</a>
Does anyone have major qualms with this? Have I perhaps missed
material in the Obscore document that would also need changes?
