Does ID naming also cover ‘namespace mapping to domain name’? That’s another issue that has big implications for the use of relationship objects, TAXII query and STIX requests/responses (which I need to do a big post about).

Versioning(if different form ID Format) and Duplicates will definitely come up again.

The only other one I can think of is revisiting versioning. Last time we talked about the relationship object it came up. I would add that towards the end of this list though.

Subject: [cti-stix] Proposal to establish Sightings (#306) and Relationships (#291) as our official issue topics under active consideration for STIX v2.0

All,

On the STIX SC call last week we talked about the issue of making immediate progress on STIX v2.0 while we work out prioritizing the full issues list and fleshing out use cases.

We proposed that we simply choose the first 2-3 issues to officially tackle based on list interest rather than any official “voting” and listed a few possible options asking for your opinions.

The list of “hot” issue options given was:

§ Sightings

§ Relationships

§ ID format

§ Abstracting constructs (identity, victim, source and asset)

§ In-line vs referencing of content

§ Data Markings

§ Other suggestions?

We did not really get back very many explicit opinions but the activity on the list since the meeting and architectural level considerations make the first two items on the list (Sightings and Relationships) fairly obvious choices for initial issues.

So, we would like to propose officially establishing that the following two issues are the active issues currently under consideration for STIX v2.0:

· Abstract Sightings into an independent construct rather than embedded within Indicator (#306)

· Abstract relationships as top-level constructs rather than embedded within other constructs (#291)

If anyone has any serious objections to this decision please let us know.

Hopefully we can continue the great discussions on these topics, going even deeper on the details, considering various options and implications and eventually reach some consensus and move on to other topics.

While the cti-stix email list is likely to continue as the primary venue for these discussions we encourage everyone to capture key thoughts, observations, opinions and proposals within the issue tracker as well as this will be the official record of our discourse and where we will eventually be declaring our consensus.

If no strong objections are heard these issues will be the primary issue topics of discussion in relation to STIX v2.0 for the SC on the cti-stix list and elsewhere.

This does not mean that other issues cannot be raised or commented on if there is need but in the interests of focus and keeping up with list traffic we would like to encourage everyone as much as possible to focus on the active issues under consideration and minimize other issue topics that are likely to distract from deliberative progress on these issues. This should be a pretty fundamental guideline for all issues as we go forward. If you have new issue topics you would like to raise or comments on existing issue topics that are not under active consideration we encourage you to enter these in the issue trackers at any time.
