Archipelago Commons, or simply Archipelago, is an evolving Open Source Digital Objects Repository / DAM Server Architecture based on the popular CMS Drupal 9/10 and released under GPL V.3 License.

Archipelago is an ensemble of deeply integrated custom-coded Drupal modules (made with care by us, METRO's Digital Services Team and contributing colleagues in our shared field) and a curated and well-configured Drupal instance, running under a discrete and well-planned set of service containers. Archipelago was designed as a multi-tenant, distributed, capable system (as its name suggests) and can be implemented as standalone or in flocks of connected deployments, sharing services.


METRO is a non-profit service provider that helps libraries, archives, and museums excel at their work. METRO works to create a sustainable culture of creativity, collaboration, and open exchange for libraries, archives, museums, and cultural institutions in the Metropolitan New York region and around the world. We accomplish our mission through leadership, grantmaking, resource sharing, professional learning, research, technology services, creative practice, and more. We strive toward a world where communities’ aspirations are uplifted in the libraries, archives, museums, and other cultural institutions they build.
