Hi Mark, hi all, <br>
<br>
<br>
Many thanks for the update and corrections in the document which
improves in clarity , namely for the observation , dataset Ids . <br>
Only minor suggestions below.<br>
My comments in slanted font:<br>
<br>
stdRefPosition: appears first in 3.10 and is defined in 6.4 in the
datatypes. </i><i><br>
</i><i> that would help to have a reference link to the definition
on the first occurences in the text. </i><br>
<br>
p67.<br>
<i>Dataproducttype enumeration list contains one literal equals to
'MIXED Some combination of the other options'.</i><i><br>
</i><i>Are there any service implementations currently using this
kind of data product type?<br>
<br>
The problem of </i><i>combined , and or complex datasets is not
supported by this Spectrum model. <br>
There will be a discussion in Sesto In DAL on the use of DataLink
and existing models to tackle these situations .<br>
</i><br>
p65.<br>
The concept of the ”nu L-nu” or ”lambda L-lambda” luminosity flux,
or equivalently the<br>
luminosity per logarithmic energy interval L(log nu), is a distinct
concept in the world of spectral<br>
energy distributions - and it’s a di erent concept from the
bolometric luminosity, ff which has the<br>
same units. The UCD board has not yet approved a UCD expressing this
concept; we have to<br>
use phys.luminosity and infer the concept from the units.<br>
<br>
<i>is this an implicit request for a new UCD </i><i>? this can be
taken into account in Semantics </i><i>, I sent a request for
that.</i><br>
<br>
p97. <br>
• A Photometry Filter may not be serialized in the same file as the
photometric sequence.<br>
There is no mechanism for serializing a reference to another
extension within the same file.<br>
It may be referred to via the keyword holding the reference URI.<br>
<br>
<i>I am not sure I understand this paragraph : do we need an example
here to show </i><i><br>
</i><i>how to link an example of a spectrum (spectrumDM2.0 ) to a
filter description from Filter in PhotDM?</i><br>
<br>
<i>RefPos vs referencePosition:</i><i><br>
</i><i>all Frame in the text use the attribute name
'referencePosition' but the utype list uses 'RefPos' like in
CoordSys.FluxFrame.RefPos</i><i><br>
</i><i>if the utype string does not matter why not homogeneise and
use 'referencePosition'in the Utype string. </i><i><br>
</i><i>This will be generated this way </i><i>in both cases : VODML
serialisation or legacy utypes </i><i>, I suppose.</i><br>
<br>
thanks , Mireille.<br>
