Archipelago Commons: blooms, new growth and healthy trees from the community garden.

Archipelago Commons, is an open source repository platform developed and supported by the Digital Services Team at the Metropolitan New York Library Council. Our team also supports over 30 deployments in the United States and internationally, as well as the wider community of self or vendor managed implementations at libraries, archives, and museums. Archipelago has achieved a steady, healthy maturity with 5 major releases since initial platform launch in 2019, paired with the advancement of a stable development roadmap. Our platform consists of slim, innovative custom-coded Drupal modules, a curated list of powerful community built software, and custom service containers with a well documented cero-to-production deployment strategy. Archipelago features a flexible open-schema metadata approach, dynamic and on-the-fly schema transformations and IIIF integrations woven throughout supported by a vast variety of Media and data viewers. Most recently, our team has been exploring and developing implementations for new tools, including semantic search and ML-assisted cataloging. Our active community and practitioner-based working group also regularly bring workflow discussions and use cases to our team, which we actively support and often inspire advancements in code development and documentation. Our presentation will focus on community favorite features, lessons learned and our future roadmap.
