[csp] Astropy - IVOA - pyVO follow-up online discussion in May

Wed May 19 18:35:19 CEST 2021

Hi Adam,

Thanks for responding. Of course you can join the zoom without registering but it is completely free and gives you no obligation to attend any of the other sessions nor any other obligations of any kind really. You can find the zoom links in the agenda page <https://wiki.ivoa.net/twiki/bin/view/IVOA/InterOpMay2021> once they are set up.

Would you like to share your views about contributions to astroquery from observatories and pyVO to facilitate coordination or would you rather follow the presentations and participate in the discussion afterwards?

Many thanks again for your message,

Bruno

I hope you are fine! ;) but I think it would be great to hear from the three main current pyvo maintainers, namely, Adrien Damian for CADC, Christine Banek for VRO and Javier Durán for ESA, on their experiences contributing code to pyvo and/or astroquery from our different organisations. This could be as Adrian suggests in a single presentation of in separate ones, as you prefer. We have a full hour for the session.

What do you think?

Hopefully a short discussion later in the month could help our two communities continue to improve further our currently working collaboration. Please feel free to bring up any issues that you would prefer to discuss beforehand and we can certainly have a short zoom meeting if you guys think that would help making the meeting more efficient.

As you say, at a high level it will be interesting to discuss what is going well and what could work better, and what the current thinking is on pyvo becoming an astropy coordinated package.  IVOA contributions to pyvo (and astropy) have been increasing, but more participation would obviously be better.  These lower level specific questions regarding where VO functionality should be built and maintained may also help inform the discussion:
