I think one of the problems I had (apart from real life catching up)
was being too ambitious with it. I tried to simultaneously port
(rewrite) it for KDE4, make a fancy new QGraphicsView UI and also
change the file format to be compatible with the IMS QTI standard .
This all proved to be too much and it was taking far too long to get
anywhere before anything even basic worked.
While supporting a new file type might seem like a big thing I decided
it was worth doing since it would provide interoperability with other
software such as Moodle etc. However, I had trouble narrowing down
decent use cases for the software and so I think I was trying to make
it do too much. I think KEduca really needs some well-defined goals,
use cases and expected work-flows as well as reasons why it is
preferred over other software such as Moodle. We need to know where it
fits in the software landscape. Without this, it is impossible to be
able to plan which features should be added.

For this reason, a raw port alone must be achieved somehow.

Give the experience I had, I think that finding someone to do an
almost direct port to KDE4 without adding any new features would be
the best way. It's a simple enough codebase that a full direct port is
well within the scope of GSoC with perhaps even potential for much
cleanup and code simplification.
Once the port is done, then work could start on adding fancy new features.

I am willing to help be a mentor for this but I am not sure I have the
time to do it by myself. If someone would be willing to co-mentor with
me then I will be able to help.

I think it's certainly a valid project and given the real impact and
use it gets, we should get some interest. We just need to work out how
to advertise its sexiness!
