Dryad Features


Securely hosted by Max under our ISO accreditation, DRYAD can be accessed from anywhere with an internet connection, either as a ‘logged in’ user for updating the archive catalogue, or as a member of the general public for searching the archive. All you need to access the system is a standard internet browser. All archive records (if deemed available for general public access) are accessible from search engines, such as Google and Yahoo.

User access and management

We can develop a hierarchy of user permissions that define what material a particular user type or group is able to see or edit. This includes a client administrator profile allowing control, creation and removal of users internally.

Open source

AtoM software is freely available, released under a ‘General Public License, giving you far more freedom than propriety commercial Archive Management Systems. Your data will never be ‘locked in’. We believe that an important part of ‘open’ is accessibility, and that everyone should have access to the tools they need to preserve and share cultural heritage materials (subject to controlled user permissions).


AtoM was originally built with support from the International Council on Archives and is industry standards compliant e.g. ISAD(G).

Legacy data & migration

DRYAD includes utilities to aid the simple migration from existing Archive Management Systems such as CALM and from other structured datasets such as excel and/or paper-based records.

Constantly improving

AtoM is an active, dynamic open-source platform with a broad user base. The system is constantly being updated with additional features and improvements. Our DRYAD service includes updates and new releases as part of our standard subscription package.
