This sounds more like a media type than a URI. Tony Hansen On 4/27/14, 2:56 PM, Gerardo Capiel wrote: > Paul, > > Thank you for your questions.

The 'math' URI scheme and protocol handler can be used by Web browsers and other applications to transport mathematical expressions to other applications, such as Assistive Technologies or graphing calculators. If you are interested this proposal, please join:http://www.w3.org/community/groups/proposed/#mathprotocol.
