Discussion:
What is the usefulness of choosing 'iodef' versus 'afrf" ?

I've always been a little confused with the distinctions between
the 'iodef' Incident Object Description Exchange Format or 'afrf'
Authentication Failure Reporting Formats.

Obviously, afrf has become the defacto standard, as that's all I see in any
DMARC record that I examine.

I've reviewed https://tools.ietf.org/html/rfc5070 and am no closer to
appreciating the impact of selecting one format over another.

Is this an example where one standard as been publically accepted and the
competing standards are more or less deprecated in deployment ?

Thanks, Jack

My understanding is that IODEF is supported by Incident Response tools so
if you wanted your DMARC reports to feed in to one of those, you'd pick it.

I haven't encountered this use-case yet with a deployment so this is just
my guess.

They're different applications so they use different schemas. DMARC
reports don't describe incidents, and are unlike the stuff IODEF is
generally used for, phishing and DDoS.

There are plenty of applications that use iodef; start here:
