We are planning the next DDI4 sprint for the week of April 11-15 in Edmonton, Alberta, Canada (the week after NADDI). The goal of the sprint is to complete a consistency review of the DDI4 modeling, particularly reviewing consistent use of patterns. If you can participate in the sprint (either in person or virtually), please contact Jared Lyle (email@example.com). More information will be posted here: https://ddi-alliance.atlassian.net/wiki/display/DDI4/Sprints.
Another sprint is planned for the week of May 23-27 (the week before IASSIST). Details of this sprint, including goals and specific location in Norway, are under development.
