You will probably need to overwrite ptxd_make_world_license() and expand it to generate the needed per package data. Then you can use ptxd_make_license_report() as a template to generate the final file. > Out of my experience with these topics (license compliance, due > diligence by laywer), the todays report is wonderful ! > And sufficient here.

I meant a file format that's easy to parse later. One of the problems here is, that the data structures get rather complex and are not something that can really be handled in shell scripts. > > I'd like to avoid escaping problems if possible. > > Me too :-) > CSV is always fun... > > Looking at the minimal information (package name, version, license tags, > maybe flags), I think we will not run into encoding and escaping issues > here.

Two points here: 1. just CSV or similar makes it hard to add or remove fields. 2. Depending on what you use to parse the files, 0x1F (ascii unit separator) or something like that, might be a good alternative. We use this in the permission files to avoid characters that might appear in file names.
