Linked data and archives

The Archives and Linked Data Interest Group is an informal group of archivists, metadata librarians, and technologists interested in applying pragmatic approaches to linked data to describe archival collections, institutions that hold them, and the entities associated with them.

International Rights Statements Working Group

Europeana, the Digital Public Library of America (DPLA), and many other libraries, archives and other cultural heritage institutions believe that everyone should be able to engage with their cultural heritage online. We can help achieve this by giving cultural heritage institutions simple and standardized terms to summarize the copyright status of Works in their collection and how they may be used. These simple and standardized terms we call “rights statements.” The International Rights Statements Working Group is developing a vocabulary in SKOS/RDF used for these generalized rights statements, which are intended for broad use.


I have taught graduate level classes in digital libraries and digital preservation, and a number of workshops in data modeling, API use, digital forensics, and electronic records.

Previous projects

Hydra in a Box

The Digital Public Library of America (DPLA), Stanford University and DuraSpace are partnering to extend the existing Hydra project codebase and its vibrant and growing community to build, bundle, and promote a feature-rich, robust, flexible digital repository that is easy to install, configure, and maintain. This next-generation repository solution – “Hydra-in-a-Box” – will work for institutions large and small, incorporating the capabilities and affordances to support networked resources and services in a shared, sustainable, national platform. The overall intent is to develop a digital collections platform that is not just “on the web,” but “of the web.” With funding from the Institute of Museum and Library Services, the 30-month collaborative project launched in May 2015 and is currently in the Product Design phase.


A project funded by the Andrew W. Mellon Foundation to build a best of breed, next-generation archival management system to serve as the successor for Archivists’ Toolkit and Archon. From July 2011 to December 2013, I was the project’s Technical Architect and product owner. In the summer of 2010, I organized a technical planning meeting for the ArchivesSpace planning grant and wrote a report summarizing the recommended actions and decisions.
