Firefox OS - MathML in EPUB
Published on December 18, 2013.
This is a review of the Firefox OS EPUB readers app MathML support. For testing I used A First Course in Linear by Robert A. Beezer from IDPF epub-sample repository.
Current there is two EPUB readers app in Firefox Marketplace: EPUBReader and Ab FB2 reader. The Ab FB2 reader won’t be able to load the file.
When open the file it show the cover.

Moving to the second chapter we find the presence of some MathML elements.

This is a review of the Firefox OS EPUBReader app. I can’t find the license of this app but probably it’s similar to the one of EPUBReader Firefox extension that can be found here (it’s not compatible with GPL). For testing this app I used:
- A Christmas Carol in Prose; Being a Ghost Story of Christmas by Charles Dickens from Project Gutenberg and
- Moby Dick by Herman Melville from IDPF epub-sample repository.
It has a very simple home page with a single button in the top that list the files that can be open.

This is a review of the Firefox OS Ab FB2 reader app. Look like that it’s source code is available in Google Code and it’s GPLv3. For testing this app I used:
- A Christmas Carol in Prose; Being a Ghost Story of Christmas by Charles Dickens from Project Gutenberg and
- Moby Dick by Herman Melville from IDPF epub-sample repository.
The home screen of Ab FB2 reader isn’t very clear.

After select the file it will try to “load” it all at once and because of that can’t open Moby Dick (Being a Ghost Story open after some time).

This is a report about the Mozilla MathML IRC Meeting (see the announcement here).
The meeting was good to break the silence in #mathml channel, meet some folks that work with MathML and start talking about regular virtual meetings and the MathML development.
Note
We use this PAD to list the topics for the meeting (backup of the pad here <pad.txt>) and the log of it is available here <meeting-log.txt>.
