# Worked example: an email message and its reply . A gmeow:EmailMessage
# carries the RFC 5322 envelope as first-class edges to gmeow:EmailAddresses —
# gmeow:from, gmeow:to, gmeow:cc — plus a gmeow:subject. Threading is a relation
# between messages, not a flat field: a reply points at what it answers with
# gmeow:inReplyTo, so the conversation graph is reconstructable from the messages
# themselves. The EmailAddresses are the reified gmeow:ContactPoints of the
# contacts slice — the same objects a person reaches mail through.
