5.

6. Use Case Discussion Please review existing use-cases on the TAXII Wiki https://github.com/TAXIIProject/TAXII-Specifications/wiki/TAXII-2.0-Use-Cases Please give us your comments, ideas, and feedback Directly on the wiki Sending them to the email list Sending them to us privately Use cases will be coordinated across the full TC May form the basis for an OASIS Work Product?

7. Protocol Discussion Heard a lot of support for HTTP, not much support for alternatives Is there a strawman consensus, or do we need further deliberation? “Strawman consensus” means we will move forward with a given protocol This also means that if we figure out later that it does not meet the requirements or proves to be too difficult to use, we will reopen this discussion. So this is not an irreversible decision, but should be considered our direction unless compelling information comes out later that warrants us to revisit this discussion and therei is a general consensus to do so. Suggestions were: HTTP/1.1, HTTP/2, ZMTP, AMQP 0.9, AMQP 1.0, MQTT, SMTP Thank you to Jane Ginn for the Google Docs spreadsheet

8. Month Ahead Work toward a shared vision Proposals are similar, need to identify similarities/differences Coordinate and mature the use cases Enable “lookahead” discussions while focusing on “current state” discussions Keep raising questions Thank you to Joep and Sergey for asking the hard questions!
