Collabathons are a sustained collaboration effort with short sprints in service of long range shared goals implemnented by the OpenTEAM community to acomplish goals in key work streams. Each Collabathon session has a defined goal, outcome, and proposed output shaped by a community co-hosts. They may take anywhere from three to eight weeks (or even longer) to complete with likely a weekly cadence of hour long meetings to keep the momentum going.
