Following the path read from a fz file to a fzp file

I am trying to write a program which reads fz-files for a university project.
Recently I realized that the information in the fz-files might not be enough for my purposes (a very abstract description of the fritzing project (how parts are connected and such)).
I need to know the family of a part, which is a property included in the parts fzp-file.
Luckily, the path to the fzp file is an attribute of the instance tag in the fz file, so I thought I could just follow this path and read the fzp-file to get the family property.
For some paths, this works, but there are also paths like this: “:/resources/parts/core/wire.fzp”, for which it fails.
I am unsure how to best work with this. Has the colon a special meaning here that I am missing? There is a “resources” directory in the fritzing-app repo, which has the file I want to read, but does this also work if somebody does not have the repo but downloaded fritzing for example using apt? I can’t find a “resources” folder.

You need to Fritzing source repo from github. The resources directory is in there (I expect the associated parts get loaded in to the parts directory.)

Thank you.
Do you maybe know why there are some references that give a absolute path I just need to follow and references into the resources. Why not give references to the parts directory in both cases?

In a word, no :slight_smile: . That was a decision by the developers long before I came to Fritzing.
