Dear DM

We are pleased to announce a new MIVOT/MANGO implementation.

- See the detail below.
- The MANGO RFC page has been updated accordingly.

     https://wiki.ivoa.net/twiki/bin/view/IVOA/Mango10RFC

I would like to take this opportunity to remind you that the document is still awaiting review ;-).

All the best

Laurent
      on behalf of the author team and the Simbad team.


-------------------------------------------------------------------------------------------------
The Simbad cone search can return data mapped to MANGO on demand.
To access this data, append RESPONSEFORMAT=mivot to the query URL.

- Example: 
https://simbad.cds.unistra.fr/cone/?RA=269.4521&DEC=4.693365&SR=0.01&VERB=2MAXREC=1ORDER_BY=distance&RESPONSEFORMAT=mivot

Each table row is mapped to one MangoObject instance, the available
properties of which depend on the verbosity level (VERB parameter).

     VERB=1:
         - The MANGO object is identified by the main Simbad ID
         - It contains 2 properties:
             - an EpochPosition instance mapping the position only
             - A Label mapping the object main type
     VERB=2 (and 3):
         - The MANGO object is identified by the main Simbad ID
         - It contains 4 properties:
             - an EpochPosition instance mapping the position, the proper motion,
               the parallax and the velocity all with their errors.
             - Label instances mapping the object type, the spectral type and the mophology type

The Pyvo code able to process this output will be included in the next release.

The extension has been released on October 2025.
