RE: Should we pay more attention to SVG?

Dear All,

And I am a formal member of the SVG WG, though mainly lurking.

The main direction of the WVG 2 work (current version is 1.2) is to ensure context is acknowledged
E.g. Style sheets allowed to promulgate from parent web page into the SVG graphics, or not.

E.g. Is really fancy font processing and font substitution really a part of SVG or the wider web?

It seems to me that the geo-CRSs touch upon these topics, as metadata to be inherited into the SVG pictures for appropriate applications to use. Dumb applications may still consider the graphics as a n x m rectangle.

I think that this may be worth a discussion at a future SVG WG telco, or the TPAC,  if only to slap me down, hence copied to Cameron for his view, and possible wider discussion.

Chris

Please be aware that work on SVG is on-going; a Working Group is currently in operation until Oct 2016 ... see the charter [1].

_Should_ we wish to refer to SVG, then TPAC would provide a good opportunity to engage with that team in order to understand how best we can 'partition' our respective concerns.

BR, Jeremy

I agree SVG is interesting technology, and is already widely used in mapping - Lets just be careful however as, quoting the charter...

"The Spatial Data on the Web Working Group must be mindful of the needs of front end Web developers, however, it will not develop any geospatial or map rendering technologies."

So pointing to good working examples as a potential best practice is a good approach.

SVG can be seen as a set of standards for encoding vector geometry and associated coordinate reference systems in a way that is native to the web (it can be directly displayed in a (modern) web browser). It could be seen a a means of visualising data on a web page, but also as a means of publishing vector data on the web - SVG data can be embedded on a web page. So there is a supply side and a demand side. Besides that, SVG is already developed. We don't need not help further development, but we could try to align our work with SVG. Issues that are particularly interesting with regard to SVG seem to be the requirements for vector geometry encoding and coordinate reference systems. It would be very nice if best practices in those areas are somewhat compatible with SVG.

Regards,
Frans

Onderwerp: Should we pay more attention to SVG?
Hello,

I would like to direct your attention to a recent contribution that came in on the public comment list<https://lists.w3.org/Archives/Public/public-sdw-comments/2015Jul/0001.html>. My feeling is that we could try to strengthen ties between our work and SVG a bit.

I propose to include SVG as one of the existing practices in the Compatibility with existing practices requirement<http://w3c.github.io/sdw/UseCases/SDWUseCasesAndRequirements.html#Compatibility>, so that SVG is at least explicitly mentioned in the UCR document, and less likely to be forgotten about in the BP work. But perhaps there is more that we could or should do?

As an example, here<http://bl.ocks.org/mbostock/3711652> is a illustration of relevance of SVG to geographical/spatial data on the web.

Regards,
Frans
