# 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.

Usage Advice

Use when

• Use for an email contact point whose addr-spec structure (local part, domain part) or delivery target matters, or that an agent holds over a tenure.

Avoid when

• Avoid for the plain string convenience (use the gmeow:email datatype property on the agent) and for the mailbox the address delivers into (that is gmeow:OnlineAccount, reached via gmeow:deliversToAccount).

How to use

• Mint the address as an EmailAddress, fill gmeow:addressValue (and the parts where parsed), link delivery with gmeow:deliversToAccount, and carry its personal sensitivity so it is not leaked to a public consumer.

Examples

• ex:lillithEmail a gmeow:EmailAddress; gmeow:addressValue "lillith@example.org".
