w:st="on"><st1:place w:st="on">Boston</st1:place></st1:City>, at the OLPC
offices for the first time. I worked directly with Matthew Harrison, who is
working on the eBook Reader project. We started a discussion page for a common
file format for our two projects, as OEPC articles can use the same reader as
normal eBooks, at <a href="http://dev.laptop.org/wiki/EBookViewerFormatSpec">http://dev.laptop.org/wiki/EBookViewerFormatSpec</a>.
At the moment, this is a little behind, as we’ve begun to focus more on
the idea of a lightweight text formatting standard, rather than any XML-based markup.<o:p></o:p></p>

This will be developed further in the near future.<o:p></o:p></p>

</span></font></span></span></font><![endif]>After some discussion between
ourselves and Ivan, we’ve decided to use a lightweight text format for document
formatting rather than any XML-based system – in particular, we’ve
chosen to base our format on Markdown, a well-established language based
primarily on plain-text email formatting. I’m in the process of building
a formal grammar for a large subset of Markdown, allowing us to create a
high-performance, lightweight parser.<o:p></o:p></p>

with a few people I met in <st1:City w:st="on"><st1:place w:st="on">Boston</st1:place></st1:City>
(the Freelogy group) on the topic of porting my PageRank code for a distributed
system, as we’ve been offered access to a high-powered 96-node cluster.
This would allow us to run PageRank against the full English Wikipedia, rather
than just the Simple English Wikipedia, giving us more options when it comes to
the OEPC.<o:p></o:p></p>
