Re: Question on Connectors in SVG

Hello,

obviously no one from the SVG WG intends to answer, so I might try to 
give some helpful comments, although I am no member of the SVG WG ...

... but the very same topic ("status of connectors in SVG") was raised 
by me on the very same list just four months ago (see 
http://lists.w3.org/Archives/Public/www-svg/2014Jul/0006.html). The 
answer that time was basically "generally under consideration", but "not 
enough interest in the WG ", "no big need/not enough usecases", and "no 
implementor/browser support", to make it high priority.

Then, I even made an own proposal which would not need a special 
"connector" element, but just a <point> to be used as a reference within 
any other element using coordinates (line, polyline, polygon, path, and 
even circle or rectangle might use reference points instead of concrete 
coordinates), complemented by a demonstrator implementation and several 
usecases as examples. As I had five minutes time at the weekend, I added 
your usecase (network diagram) as another one ;-) If you are interested, 
you might check it (and maybe use it, enhance it, and thus make it more 
"impressive") at http://jroethig.de/geolog/connector.html#l2demnetworks

Best regards,

Juergen Roethig

BTW: Since then, connectors had been a topic again on the list and even 
discussed somewhat in a SVG F2F ("TPAC") meeting end of October, but the 
"result" (i.e. "no high priority") still seems to be the same as before. 
And well, someone who is not in the WG has obviously no possibility to 
"push" a topic, as my proposal had not even been mentioned at that 
meeting, at least according to the minutes.
