5. Ideas for HOW we do work Leveraging github n Issue trackers n Wikis n Will likely need to being thinking of the “specs” repository as primary area for STIX language l Should eventually move over appropriate tracker issues from “schemas” repository n Ideas for how else we could be leveraging github?

6. Ideas for HOW we do work Other ideas for technical enablers? n Does anyone have any other ideas for gaps/solutions of technical enablers for our work? l Discuss exploration into collaboration tools n SC co-chairs are discussing potential options n Interested in input/feedback on requirements and options l Options for managing meetings better?

7. Ideas for HOW we do work Official STIX SC Secretary? n What do people think of the idea of having an official STIX SC Secretary to organize and coordinate SC activities?

8. Ideas for HOW we do work Discussion of STIX SC work processes n Don’t want to rehash the email from the co-chairs sent on 8/1 l Do need to emphasize that under formal governance our work will need to be open, deliberative, ordered and tracked. n Encourage ideas and discussion but caution that consensus and decisions will need to follow process. l Please keep talking. :-) n Encourage contributions beyond just thoughts l As work product efforts are stood up, editors will be needed l Contributions of use cases, conceptual models, schema structures, normative or informative language suggestions, test data, etc. will be invaluable to collaborative progression n MITRE folks will continue to be involved but we will need a broader base of active contributors going forward

9. The need for use cases n The need for Use Cases has been repeatedly raised l Use cases have always been driving STIX/TAXII/CybOX but they have not been explicitly codified n Under formal governance we need to do this l This topic is being discussed across the SCs at the TC level not just for STIX l We need to capture comprehensive set of use cases for STIX n Suggestion: Initial capture and evolution in a github wiki n Suggestion: Identifying a volunteer to help coordinate this activity
