[Blindmath] Integrating SVG with DAISY and MathML

Kiran,
SVG would be the most accessible format but your statement
"S V G  is accessible in a reader or say browser with screen reader."
Is an oversimplification. Contemporary screen readers don't contain any 
real functionality to make SVG accessible. There are some products which 
can exploit SVG's structure but they are not used widely.

In theory the Viewplus Iveo touchpad in combination with their embossers 
should make SVG quite accessible, but IVEO is buggy and has not been 
updated in nearly 5 years so I have givven up on them. You could check 
out tactile view (by Jaap Breider). There may be other solutions I am 
unaware of.

Correct: "In a digital talking book usually the source file needs to be 
imported into the daisy generator program and most likely to be from a 
word or HTML file." Indeed, the source file needs to be well structured 
according to strict rules for Daisy conversion (PDF would be the only 
other commen format which enables authors to store the necessary 
headings and other structure).

"We can have an S V G  element in HTML file but not in a doc file." - 
probably correct. for HTML files you  always have easy access to the SVG 
file, in Word documents accessing the SVG file would be much harder if 
it is possible at all.

"I have been able to figure out to import an S V G file in a word file 
and hence we may populate the  ..."
Agreed - you could dynamically construct an alt tag based on the SVG 
content though it is challenging to find the best way to construct a 
meaningful image description automatically. Nice AI project.

"This is usually the practice to describe the image if any in a daisy 
conversion." - true I guess (but I'm not well informed on Daisy 
conversion products and practices).
