I personally just
don't see why we are messing with this. If we had not done this in the
2.0 spec then all of this debate could have been avoided in the first place.
There could be
solid use cases for network equipment makers to use Version 1 UUIDs when
generating STIX - we don't know.
RFC is RFC, and
it is interoperable as it is, I don't see why we would mess with it.

How
about:
The
UUID portion SHOULD be generated according to the algorithm(s) defined
in RFC 4122, section 4.4 (Version 4 UUID) or section 4.3 (Version 5 UUID)
but any algorithm defined in section 4 MAY be used. [RFC4122]

I
agree with this text.
Then we can publish a separate work product for the recommended OASIS CTI
namespace UUID(s) and the accompanying name generation algorithm(s) for
said versions.
Having it separate makes it easier to evolve and amend.

Hereâs
a little word crafting for Alexandreâs suggestion:
All
identifiers, excluding those used in the deprecated cyber observable container,
MUST follow the form object-type--UUID,
where object-typeis
the exact value (all type names are lowercase strings, by definition) from
the typeproperty
of the object being identified or referenced and where the UUIDis
an RFC 4122-compliant UUID. The UUID MUST be generated according
to the algorithm(s) defined in RFC 4122, [RFC4122].

All,
The
following sections are ready for TC final review. Some of these are
in different Google Documents so I have included direct links for you.
Please have all suggestions and changes in the
documents
by end-of-day Friday May 10th (2 weeks from today):
Introduction
and Overview: Section 1.6 - 1.8

Thank
you for the work.
But
the UUID description is still not solving the issue already mentioned in
https://github.com/oasis-tcs/cti-stix2/issues/133.
The
current proposal in the draft:
"All
identifiers, excluding those used in the deprecated cyber observable container,
MUST follow the form object-type--UUID, where object-type is the exact
value (all type names are lowercase strings,
by
definition) from the type property of the object being identified or referenced
and where the UUID is either an RFC 4122-compliant Version 4 UUID or Version
5 UUID. The UUID portion MUST be
generated
according to the algorithm(s) defined in RFC 4122, section 4.4 (Version
4 UUID) or section 4.3 (Version 5 UUID) [RFC4122]."
Could
this be updated in the following way:
"All
identifiers, excluding those used in the deprecated cyber observable container,
MUST follow the form object-type--UUID, where object-type is the exact
value (all type names are lowercase strings,
by
definition) from the type property of the object being identified or referenced
and where the UUID is either an RFC 4122-compliant UUID. The UUID portion
MUST be generated according to the
algorithm(s)
defined in RFC 4122, section 4 [RFC4122]."
We
have an ongoing fork for the CTI STIX2 implementation and this change could
solve a host of issues reported by several vendors / implementers that
we are in contact with.
Could
we count on the TC for ensuring this is passing in STIX 2.1? Because this
is a major blocker and I would be very disappointed to keep having to maintain
our fork of the STIX 2 libraries,
especially
considering the rather steep effort required to keep it in line.
Thank
you very much.
