[kde-edu]: KVocTrain rewrite - feature list and usecases

[Peter Hedlund]

Hi,

Very impressive work. Thank you.

I have a couple of additional items I want to discuss. 

First the libkdeedu library. As it is now there is a very rudimentary class 
for loading kvtml files. I believe we need a library with shared classes for 
maintaining kvtml documents. Now if you create an advanced file in KVocTrain, 
then load it in FlashKard or KWordQuiz, make a little change and save, 
chances are a lot of information is lost. The library should provide a kvtml 
document class that can be shared between applications and that will handle 
loading and saving without data loss. I know this will probably be overkill 
for a program like KHangman, but will allow a greater number of files to be 
used by several edu programs. Comments?

Second the kvtml file format itself. The minimum changes I would like to do 
are adding an attribute to the <e> element for storing the rowheight used 
when displaying the vocabulary, and adding <sound> and <image> child elements 
to the <o> and <t> elements. Sound and image are needed to create a flashcard 
program that can use this type of data. The elements would contain URLs 
linking to sound or image files. 

Going further than that I don't particulary like the structure of the kvtml 
DTD. It relies too heavily on attributes. E.g. comments, false friends, 
synonyms and antonyms are all attributes. The files would be much easier to 
handle and read (by human and machine alike) if these things were child 
elements instead. Comments?

Thanks,
Peter
