Summer of Code Project

Dear all,


My name is Catalin David and I am a second year undergraduate student at
Jacobs University Bremen, Germany. I have recently contacted KDE.org
because I want to do an internship this summer and Mr. David Faure told
me that the only way to do an internship and actually get it
acknowledged as an internship is through the "Summer of Code" Google
program and that I should seek help on the webpage.

Since the webpage here
http://techbase.kde.org/Projects/Summer_of_Code/2009/Ideas#Guidelines 
says that "If you are not a developer but have a good idea for a
proposal, get in contact with relevant developers first.", I thought I'd
give it a try here in order to find a support and, hopefully, a mentor.

So, my project regards the implementation of MathML standard for
Konqueror ( https://bugs.kde.org/show_bug.cgi?id=30526 ). I am really
interested in this because I have already worked in this domain for some
time. Here, at the university, I am part of the arXMLiv research project
( http://kwarc.info/projects/arXMLiv/ ) which has the aim of
transforming the entire database of articles at www.arxiv.org to XML and
then, to XHTML + MathML using LaTeXML ( http://dlmf.nist.gov/LaTeXML/ ),
with multiple purposes.

Since the website requires this information:

The expected end-product is a similar-to-Firefox MathML formula parser
that is able to display MathML.

The prerequisites for this are C++ and Qt (I assume).


Thank you in advance for the replies,

Catalin David

You might want to take a look at KFormila and http://www.qtsoftware.com/products/appdev/add-on-products/catalog/4/Widgets/qtmmlwidget/

I'm actually integrating this in 2nd in KAlgebra by now...

I support the project, and would happily mentor it.

I would propose that implementing the MathML engine is best done inside KHTML or WebKit. It has many of the needed components.

When displaying something in KHTML or WebKit what happens is:
Input is parsed into a DOM-Tree.
Any javascript is executed during parsing and modifies the DOM-tree.
The DOM-Tree is styled into a CSS-like Render-tree
The render-tree is layouted.
The render-tree is rendered.

- Since MathML is XML, the parsing is already fully supported.
- If there is standard for how MathML DOM works, that has to be implmented in the DOM-part, otherwise nothing has to be done in DOM.
- There is no finished standard for CSS for MathML, so part if the project will be to invent some CSS-like extensions that are needed for us to style and layout MathML
- Layout algorithms operate on the same invented CSS, and has to match MathML spec.
- Last rendering will mostly reuse exiting KHTML components, but some things like stretching parentheses, integrals or squareroots will have to be implemented.

So what you need to do this, is a good understanding of both MathML and CSS.

Hello Allan,

I would support that too. So if you need some institutional support, I think I may be able to help. If it is on MathML or XHTML, this could also be combined with W3C internship.

Best,

Rigo
