Ok, so if I understand correctly, the #MailMessage doesn't have any
additional properties, so by using purely the SIOC types I would lose
some information from the headers. Some of the linking information
(References, In-Reply-To -> Message-Id) could be retained by creating
#Container objects. But that would require the converting system to
have access to all previously received messages.
So right now I like the Nepomuk approach better, to have a class per
header plus a generic MessageHeader class for additional headers.
How are such situations usually resolved? There now seem to be two
classes (sioc:MailMessage, nmo:Message) that both have the same
purpose. Is there a way to "combine" them, so that software
understanding one, but not the other can take the information it
understands and ignore the rest?
My brain hasn't fully adapted to RDF yet, I'm shooting a bit in the dark here :)
