PyVO and DM

[Salgado, Jesus]

Dear DM,

First proposal for an PyVO API  using data mapped on a DM.
This proposal is based on a suggestion presented by Gilles Landais in May 2021.

TLTR
------
At last Interop, we have had a PyVO hands-on session where we have open a discussion on the requirements for a PyVO API processing annotated data.
The minutes of that session are on GitHUB (https://github.com/ivoa/modelinstanceinvot-code/wiki/hack-a-thon-contributions).We all agreed that this new API must have no impact on the current one and that its design must be based on real use-cases.

The expectation for using annotated data is not necessary to allow doing new things. It is rather to facilitate common operations.To move on, we have decided to start from some typical PyVOT codes and to figure out how to do the same things with a code based on annotated data. The rule is to write realistic pseudo-code.We are proposing now a brief discussion focused on a first sketch based on the proposal presented by Gilles in May 2021 and taking advantage of the experience we got while exercising MIVOT parsing.

Best Regards
LM - JS
