WD-DALI-1.2

[gilles landais]

Hi,

thank you for the new DALI version -

my feedback is  focused on VOTable output.
I have a lot of interest on the document that shows points that could 
improve in general the VOtable.

For instance the semantic and the sexagesimal xtypes inspire me to 
improve VOTable returned by the VizieR service (there are a lof 
sexagesimal columns in VizieR).


About the section 5.4 Use of VOTable.

* about Error report: (already in the current/previous version) the 
method between DALI and SCS are different

- SCS requires: ID="Error" name="Error"
- DALI requires:  name="QUERY_STATUS" value="ERROR"

* I like the idea (already in current version) of information 
"standardID" and "citation".
If I understand, these are applied on the resulted VOTable - but the 
INFO proposed sounds more like service information than Dataset information.

We could enrich VOTAble the header with other information (see 
https://ivoa.net/documents/DataOrigin/)
For instance, "citation" could be applied to the Dataset, but also to 
external resource like the original resource (example Gaia tables) or an 
article used to create the Dataset. More important, the ivoid  should be 
added for the service (standardID) but also for the Dataset(s) (to make 
the link with information in the registry)

I think too, that decorate the result with information like authors, 
publication date should be interesting.
Nevertheless, is it possible to propose in DALI 1.2 at least the ivoid 
of the Datasets used?

Something like: <INFO name='ivoid' value='ivo:...' />


Regards,

Gilles Landais (CDS)
