The Sustainability Working Group (WG) determines the most cost-effective way to deliver ARK services that provide value to the community while keeping the required contribution from the community affordable. It conducts an ongoing conversation in the ARKs-in-the-Open (AITO) community about costs and how they will shape the “minimum viable product” and any additional services. This WG is concerned with long-term organizational and financial stability for ARKs and ARK infrastructure, whatever that will end up meaning precisely, and its work will be cognizant of legal and tax frameworks (eg, non-profit organizations).

A short 2-3 sentence description of why the working group has been formed and what it will accomplish for the project.


  1. Cost analysis. As a starting point, determine the cost categories and totals involved in keeping the current ARK infrastructure ( resolver included) running, monitored, patched, replicated, and updated with features that keep it interesting to the community. Determine which costs are essential and which costs could be reduced or eliminated if necessary in order to achieve sustainability.

  2. Revenue strategies. Determine ways to bring in income and/or in-kind resources necessary to sustain the service on an ongoing basis, as well as sufficient buffer to maintain it for a year even if the income stopped. Examples include one or more of subscriptions, fundraising events, contributed staff time, tiered memberships, etc. It will be useful to be able to state how these strategies are expected to avoid the problems experienced in 2018 by DPLA and DPN.
