In order to support this, at a minimum we'd need to define additional properties on the artifact object to capture the archive method (zip, tar, etc) and the ordering of the archive in order to enable consumers to reassemble and extract the split archive. We could of course decide to add these capabilities but as we already have a mechanism designed specifically to address sharing artifacts <10MB (via the artifact url property) I'd be curious to hear from others for whom this does not work. One of our core design principles for STIX 2 has been to avoid creating two different ways of accomplishing the same thing wherever possible - which this would certainly entail. Design principles represent an ideal that we strive for but meeting the needs of the CTI TC community can justify making pragmatic exceptions. I think we'd need to hear from some additional voices before taking such a decision. -- Cheers, Trey ++--------------------------------------------------------------------------++ Director of Standards Development, New Context gpg fingerprint: 3918 9D7E 50F5 088F 823F 018A 831A 270A 6C4F C338 ++--------------------------------------------------------------------------++ -- "Law stands mute in the midst of arms." --Cicero
