The encoding used for Involved People and Musician Credits mappings in APE files is:
mapping=name (role)
Yate is very forgiving when reading this mapping. It can handle missing names, missing roles and will allow more than one definition per line. The following will all work as expected:
mapping=John Doe (Guitar)
mapping=John Doe (Guitar,Vocals)
mapping=John Doe (Guitar/Vocals)
mapping=John Doe, Jill Doe (Vocals)
mapping=John Doe, Jill Doe
mapping=John Doe (Guitar,Vocals); Jill Doe (Vocals)
mapping=John Doe (Guitar,Vocals) Jill Doe (Vocals)
mapping=John Doe (Guitar,Vocals), Jill Doe (Vocals)
