Dia extensions


It's my first time I write to this list.

I'm writing because I wanted to write a program, but I concluded that Dia would do the job better. I want to know if my problem can be solved by Dia.

My idea was to write a program to help CS students from Barcelona's CS Faculty (FIB) to choose among the different optional subjects. You may say ''Dear Dani, it is not a so difficult task!", but it is! The thing is that, as many other faculties, FIB has a lot of optional subjects (and they are more than 1/3 of your curriculum) and they have requisites among them. The goal of the program would be to draw a diagram of the subjects you would have choosen, but furthermore, it would help with requisites and automatically would draw any requisite of any subject you would choose.

I think that there isn't any problem to create a new library, like UML, Sybase or any Dia library, where each member would be a subject, with information related to it, hours per week, teachers, etc... But my question is the following: imagine I have created my subject library: I have the subject CL1 (compilers I) and CL2 (compilers II) for example. I click on CL2 and I drag it in my Dia sheet. Because CL1 is a requisite of CL2, it would be desirable to Dia draw it for me (and furthermore, draw a "link" between both subjects). And also check if, in the current sheet, I haven't spent all week hours for optional subjects.

I have not read any Dia source code line yet, at the momment I'm only looking for advice.

Thanks in advance. Excuse me if my written English is bad (my spoken English is worse :-) )
