Max Eckard, Dallas Pillen and Mike Shallcross have published "Bridging Technologies to Efficiently Arrange and Describe Digital Archives: The Bentley Historical Library's ArchivesSpace-Archivematica-DSpace Workflow Integration Project" in the Code4Lib Journal.
Here's an excerpt:
In recent years, ArchivesSpace and Archivematica have emerged as two of the most exciting open source platforms for working with digital archives. The former manages accessions and collections and provides a framework for entering descriptive, administrative, rights, and other metadata. The latter ingests digital content and prepares information packages for long-term preservation and access. In October 2016, the Bentley Historical Library wrapped up a two-year, $355,000 grant from the Andrew W. Mellon Foundation to partner with the University of Michigan Library on the integration of these two systems in an end-to-end workflow that will include the automated deposit of content into a DSpace repository. This article provides context of the project and offers an in-depth exploration of the project’s key development tasks, all of which were provided by Artefactual Systems, the developers of Archivematica (code available at https://github.com/artefactual-labs/appraisal-tab).
