On 18-19 May, 32 scientists from the USA and Europe, representing 23 modeling organizations, met to discuss the Open Modeling Foundation initiative. With a few short presentations to provide attendees with context and background, most of the meeting was dedicated to discussion of the OMF initiative and its organization, community modeling standards, and the drafting of initial standards documents. The participants piloted a new collaborative decision-making platform, based on GitHub, as a way to work as an international organization with distributed governance to develop and administer common standards for modeling. The results of the outstanding efforts of the workshop participants can be seen at the new site: https://openmodelingfoundation.github.io. The documents and ideas contributed by the participants will be used as the basis for the next OMF planning meeting, provisionally planned for early September 2020.
