[BONNAREL FRANCOIS gmail]

Dear all,
I will not attend the meeting today. But as a still-editor of the  Radio 
extension I will add my personal 2 cents on the  points of Obscore extension
This si not fully coordinated with the two other editors (Mark K and 
Mireille)

For the radio one, I start by copy/pasting the RadioIG charter now 5 
years old

> *Charter:*
>
> The group shall define requirements for the representation of radio 
> astronomy data in the VO through:
>
>   * development of use cases for data discovery, access and visualization
>   * identification of metadata concepts needed by radio astronomy data
>     that are not currently supported by the VO
>   * the group will provide a well identified point of contact for
>     radio projects with IVOA, and actively encourage their use of VO
>     standards and protocols
>   * the group will organize sessions focused on radio astronomy data
>     at IVOA meetings

I think the radioIG group basically succeeded in providing point 2 with 
the extension PR and the prototypes and implementation at JIVE. I also 
appreciate that last version of CAOM integrated most of the extension 
attributes in its own scheme in order that ObsCOre + extension will 
remain a flat discovery-intended view on top of it.

The radio extension proposal has been regularly discussed not only in 
RIG sessions but also in DM sessions.

On the  other side I understand that now people fill the need to rework 
ObsCore and that this upgrade can rearrange the limit between root 
Obscore and the radio extension

(not to speak about the time and Heig ones). I think the final 
perspective may something like the vision expressed by JJ in a recent 
email : a global metadata model and various specific and one root 
generic subparts.

My main concern is that achieving this will take a lot of time (22 years 
in the VO showed me that no new project achieves fast, whatever the 
intentions are at the beginning. Some unsuspected aspects always appear 
in the process). So what is the status of the radio extension in the 
mean time ? I think some projects are ready to use them. Howgive can we 
give these attributes a normative status

As some of you already know my compromise proposal is to publish the 
draft spec as an "endorsed note" during the time Obscore 1.2 is discussed.

Cheers

François
