About THE ALEXANDRIA ARCHIVE INSTITUTE

The Alexandria Archive Institute (AAI) is a San Francisco–based 501(c)(3) nonprofit that develops open web technologies, advocacy, research, and education to preserve and share archaeological and cultural heritage data. Its signature platform, Open Context, provides open-access publication and archival services for structured archaeological data and associated media. AAI operates as a small, grant-supported organization that partners with universities, museums, foundations, and federal funders to sustain long-term access to research data and to run data literacy and community-centered projects.

Notable achievements

Scale of Open Context (growth through 2025)

Open Context has grown into one of the world’s largest open-access archaeological databases; by the end of 2025 it hosted nearly 2.4 million records from over 200 published datasets, including hundreds of thousands of images, maps, documents, 3D models, and GIS layers.

NSF sustaining grant (2024)

In 2024 AAI secured a multi-year, five-year National Science Foundation award to sustain Open Context as a collaborative data infrastructure for archaeology, providing core funding to support long-term operation and development of the platform.

IMLS grant for FAIR+CARE (2023)

In 2023 AAI received a National Leadership Grant from the Institute of Museum and Library Services (~$699,475) to lead the Advancing FAIR+CARE Practices in Cultural Heritage project, supporting development and dissemination of ethical data governance and FAIR+CARE guidance for heritage data practitioners.
