Members of the OASIS Open Command and Control (OpenC2) TC create and manage technical content in this TC GitHub repository ( as part of the TC's chartered work (i.e., the program of work and deliverables described in its charter).

OASIS TC GitHub repositories, as described in GitHub Repositories for OASIS TC Members' Chartered Work, are governed by the OASIS TC Process, IPR Policy, and other policies, similar to TC Wikis, TC JIRA issues tracking instances, TC SVN/Subversion repositories, etc. While they make use of public GitHub repositories, these TC GitHub repositories are distinct from OASIS Open Repositories, which are used for development of open source licensed content.


This GitHub repository supports development of content and change tracking for the OpenC2 OpenDXL transfer specification as new working draft level revisions are created and the associated CSDs mature. OpenDXL is a messaging bus which provides a standardized application framework for the sharing of information in real time.

This repository is designed to support TC members' work on a formal specification that describes the use of OpenDXL as a transfer mechanism for OpenC2 messages. The provisional Work Product title is "Specification for Transfer of OpenC2 Messages via OpenDXL, Version 1.0", edited by Duncan Sparrell (sFractal Consulting) and Scott MacGregor (McAfee). The specification explains the transfer of OpenC2 command and response messages using OpenDXL.


This repository is organized with three branches:
  • The Working branch contains work product material that is actively being developed, and subject to potentially frequent and significant change. Contributors to the work product should target their inputs to the Working branch.

  • The Releases branch contains incremental releases (i.e., Working Drafts) of the work product. The current contents of the Working branch are merged into the Releases branch to create a working WD.

  • The Master branch contains TC-approved Committee Specification (CS) and OASIS Standard versions of the work product. Until the first CS is approved, the Master branch will not contain a complete version of the work product.


As stated in this repository's CONTRIBUTING file, contributors to this repository are expected to be Members of the OASIS OpenC2 TC, for any substantive change requests. Anyone wishing to contribute to this GitHub project and participate in the TC's technical activity is invited to join as an OASIS TC Member. Public feedback is also accepted, subject to the terms of the OASIS Feedback License.
