RE: Rechartering the SDW-IG after December 2019

Hi Jeremy and Linda,

Looks good to me.   On the other hand, I have comments. :-)

> what should it's terms of reference
> be?

In my mind, the SDWIG has always been about the webification of OGC standards and the spatialization of Web standards.  But perhaps that's too ambitious at the moment. 

We have been focusing on individual standards developments, whereas I think SDWIG provides a good opportunity to talk about aspects of standards and standards development that relate to both organizations. Thinking about the strengths that the two organizations bring to the SWDIG, perhaps we can still craft a re-chartering to leverage complementary strengths and hence provide advice to both.  

W3C: Web scale architecture (domain independence), accessibility, privacy, internationalization, performance, intersecting WHATWG / W3C membership, Community Groups program, ...

OGC: geospatial domain experts and expertise, crowdfunding / Innovation program, stable usable standards that are widely implemented, intersecting global SDI-Open Data / OGC membership ...

I think growing and improving the list of strengths of the other side should be in scope, through the activities and advice of the SDIWG.

Two meetings per year is appropriate, especially including  one at an OGC venue and one at TPAC, I think.  

Thanks for asking.
