DM Workshop report

[Laurent Michel]

Dear all,

I wrote a short report on the DM workshop

     https://raw.githubusercontent.com/ivoa/dm-usecases/main/doc/tex/report-note.pdf

The conclusions are copied below, so that no need to open the PDF.

We are now working with Gerard and Mark CD on a joined proposal for the syntax.
I hope to be able to present the outcomes of this big job during a running meeting within a couple of weeks.

====== Conclusions ==================================
5.1 What Worked Very Well

	• Data contained in all 5 use-cases can be modelled with existing models

	• The 2 annotation syntaxes have been used with success

	• All APIs have been able to process all annotations.

	• It has been demonstrated that Enabling AstroPy or PyVo to work with annotated data is feasible without breaking the regular data access.

5.2 What Has to Be Improved

	• The connection of PhotDM with Meas/Coordinate/Mango/Cube has to be tuned. This is a pending issue while the PhotDM VODML/XML has not be released.

	• Some update of Meas/Coordinate have been suggested, especially for the sky positions (see RFC2 page).

	• Some class rearrangements have been proposed in the MANGO Pa- rameters.

5.3 What Has to Be Discussed

	• It is very desirable to finally have one syntax. There are ongoing discussions to merge both proposals

	• Extending our models to cover new use cases
