Subject: Re: [EXT] [cti] STIX action items for the full TC call on 6/15/17
For opinion, I am still concerned about the scale. I think we are leaning towards an open-vocab or ENUM of values. But I am not sure we have the fully consensus of the TC on this. Yes it has been discussed on several working calls, but that is just a subset
of this whole group. Opinion also does not have the ability to link against a specific version of an object. So you may issue an opinion but the object may have been updated and your opinion is no longer valid. Further, I really worry that we do not have
digital signatures yet. I think supporting the Opinion object before digital signatures is like putting the cart before the road.
For note, I do not agree with having a "name" on the note. I do not think it makes sense to have a "name" for a note.

hear your concerns on what questions remain as that may help us think through ways to implement in AIS. Thanks! W. Preston Werntz Chief, Technology Services Section National Cybersecurity and Communications Integration Center (NCCIC) Department of Homeland Security

On Behalf Of Bret Jordan While I think note/intel-note and opinion are making progress, I personally do not feel like they are done enough to add to the 2.1 documents. I think there are several unanswered questions. I think they need
some more time and discussion before they are done. Bret From: cti@lists.oasis-open.org <cti@lists.oasis-open.org> on behalf of Sarah Kelley <Sarah.Kelley@cisecurity.org> On tomorrow’s working call, we will be addressing several topics that need TC consensus for moving forward with STIX 2.0 and STIX 2.1. In preparation for the meeting, please review the following: STIX 2.0:
?
The second open comment period for STIX 2.0 has closed. The suggested changes have been addressed on working calls, and the current decision on each item has been documented in the following spreadsheet: https://docs.google.com/spreadsheets/d/1YOPONeKzc6Uu1A1MS3WkICG26LKLQOWdr-KBDzM8K6Y/edit#gid=5055878
?
The TC needs to fully approve these changes before we can consider STIX 2.0 CSD to be done. There were no substantive changes made during this comment period, so if the TC agrees to the decisions
documented in the spreadsheet above, we can vote to move forward from a Committee Specification Draft (CSD) to a Committee Specification (CS).
?
ACTION ITEM: Please review the spreadsheet. If you have any objections to the decisions as listed,
please comment either on the list or at the full TC meeting tomorrow. Lack of comment is considered to be agreement. STIX 2.1
?
Intel Note is ready to be moved from the STIX Working Document to the STIX 2.1 Specification Document. As such, we agreed to open each item up for approval
of the full TC. The current proposal is located here: https://docs.google.com/document/d/15qD9KBQcVcY4FlG9n_VGhqacaeiLlNcQ7zVEjc8I3b4/edit#heading=h.s5l7katgbp09
