Archipelago Commons, is an open source repository platform developed and supported by the Digital Services Team at the Metropolitan New York Library Council. We support 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.

Created in 2018, Archipelago has achieved a steady, healthy maturity with 8 major releases since its first public version in 2019, paired with a stable development roadmap. Our platform consists of slim, innovative custom-coded Drupal modules, a curated list of trusted community built software, custom service containers and well documented zero-to-production deployment strategies.

Archipelago features a flexible open-schema metadata approach, dynamic and on-the-fly schema transformations and deep IIIF API integrations supported by a vast and ever growing variety of Media and data viewers.

Our 2025 focus was on improved discovery, better date processing math, UI vector integration for semantic search and ML-assisted cataloging and clustering, new batch ingest and background processing options, and also out-of-the box AI/ML bot harvest mitigation tools.

Our presentation will focus on community favorite features, lessons learned and our future roadmap.

The Dataverse Project is an open source web application to share, preserve, cite, explore, and analyze research data. It facilitates making data available to others, and allows researchers to replicate others' work more easily. Researchers, journals, data authors, publishers, data distributors, and affiliated institutions all receive academic credit and web visibility.

In this presentation, we will first introduce the project and discuss the core architectural principles defining the software, as well as the robust open source community. We will then review updates from last year, highlighting key features from each release and the current status of the re-architecture project separating the front end UI from the back end APIs.

An overview of Islandora in the context of the latest generation of Open Source Digital Repository solutions, highlighting core functionality, integrations and collaborations with other Open Source projects/communities, and a showcase of live repositories. This presentation will also include an update on Islandora Foundation activities and accomplishments from the last year.

The Open Science Framework (OSF) is a free, open-source platform designed to support researchers through the full lifecycle of the research process. OSF serves as both a generalist repository for data and other research outputs as well as a workflow collaboration tool, preprint publishing platform, and study registry. OSF is a free service that has been used by more than half a million users over the last 10 years.

Since OSF is free to all, the issue of verifying the affiliation of users to academic or research institutions can be complex. To date, OSF has supported an Institutional Membership model that enables researcher login with their institutional credentials, ensuring that only authenticated representatives are associated with the institution.

In 2026, we plan to expand part of this service to a pilot group of eligible members of the InCommon federation at no charge. This will allow users to add their institutional name and identifier to all the content they create on OSF, including that shared with persistent identifier registries like DataCite and CrossRef. This enables institutions to more easily incorporate data about their institutional user’s activity back into their own catalogs and research information systems.
