Overview# Access to Memory is described as follows.
https://github.com/artefactual/atom
AtoM (short for Access to Memory) is a web-based, open source application for standards-based archival description and access. The application is multilingual and multi-repository. First commissioned by the International Council on Archives (ICA) to make it easier for archival institutions worldwide to put their holdings online using the ICA’s descriptive standards, the project has since grown into an internationally used community-driven project.
This article tries the OAI Repository functionality provided by AtoM.

It is described as follows.
AtoM has the ability to act as a data provider to service providers interested in harvesting descriptive metadata from AtoM, by exposing either simple Dublin Core XML or EAD 2002 XML via OAI-PMH, the Open Archives Initiative Protocol for Metadata Harvesting (version 2.0).
