OAC Infrastructure

OAC is based on community-supported open source technology adapted by CDL.

The OAC public website is primarily built on ArcLight, an indexing and discovery system designed specifically for the presentation of finding aids, developed by Stanford Libraries with partner organizations. ArcLight is built on the Blacklight framework, which is currently and actively maintained through community contributions by partner institutions around the world-- and stands as the most viable, tested, and durable replacement to the OAC’s current XTF system.

The OAC Dashboard, used by contributors to manage their contributions to OAC, is built with the Django web framework and uses the Apache Airflow platform to manage data workflows between systems.

All of our code is publicly available on GitHub.
