Re: [cti] Update from STIX Package renaming Mini-Group

["Jason Keirstead" <Jason.Keirstead@ca.ibm.com>]

That seems like a TAXII level problem, if anything.

I don't see how having IDs would even solve that problem, without changes to TAXII to allow someone to say something like "bundle recieved"

I agree with Jason... I know the request on the call was about how do you know if you did not get a bundle.  That seems to be an implementation / transport level issue, not a language level issue. Allan / Terry? Thoughts?   Is there another way of doing what you asked without having an ID field?


Thanks,

Bret

Open question - adding an identifier "so that it can be tracked", implies that it SHOULD be tracked.

As an implementer - why do I need to track bundles, as all a bundle is is a whole bunch of content that may or may not be related?

I would argue that we should not encourage the storage or tracking of the bundle structure, and therefore they should not have IDs.

As discussed on the call today I would like to propose that we add an identifier attribute for the bundle so that it can be tracked.

Subject: [cti] Update from STIX Package renaming Mini-Group

All,

Here is a quick update from the STIX Package name mini-group. The mini group is proposing:
• Renaming STIX-Package to STIX-Bundle
• STIX-bundle is simply a transport container
• STIX-Bundle is a grouping of STIX content that isn’t required to be related (it MIGHT be related, but being in the same bundle doesn’t mean it’s related)
• Removing all TLO Common Properties (with an open question about Data Markings)
  • Removed properties: id, created_by_ref, created_time, revision, modified_time, revoked, revision_comment, confidence, object_markings_refs, granular_markings
• STIX-Bundle will keep the `spec_version` property
• All content in the bundle MUST be the same STIX version (identified by spec_version)
There is an open question about whether Data Markings should be in the STIX-Bundle. Arguments for keeping it are:
• The group seemed to have consensus that Bundle-level markings were desired, but evidence was difficult for the mini-group to find.
• Certain sharing communities would appreciate the simplicity of package marking.
• It makes objects look smaller and is more natural for people who are new to the specs
Arguments for removing it are:
• Data Marking at the bundle level is “two ways of doing things” - on-the-object markings and on-the-bundle markings
• TLO signatures will not be valid when the Bundle-level markings are used

Thank you.
-Mark
