Thank you for suggestions. I also found book: Undocumented windows 2000 secrets. Its outdated but contains some information about PDB structure. It also has an open-source PDB explorer (probably outdated too). 
Unfortunately I have no official documentation.

I agree project is too big for one student. That's why I'd like to propose only a part. Maybe there is a student who want to cooperate? It would be nice to divide the project into parts and do it together.

AFAIK Wine's implementation of dbghelp.dll includes code for reading PDB files.
