Prism is an institutional repository for the research and scholarly output of Feinberg School of Medicine at Northwestern University

Background Information for Prism

Architecture of Prism

Prism is based on open-source architecture called InvenioRDM that is used by institutions worldwide. The repository provides stable, long-term preservation and ongoing maintenance for content contained within the repository.

The InvenioRDM software publishes a public road map which details the development of new features. 

Metadata in Prism

The descriptive metadata for Prism is primarily based on the DataCite schema, which is a standardized set of elements or terms commonly used to describe resources in a variety of formats. Because DataCite has been widely adopted by different platforms for different applications, its use ensures that the metadata input in Prism is interoperable with other systems and easily interpreted by users. For more information about DataCite, see the DataCite website and a list of the terms contained within the DataCite schema along with their definitions.

Membership in COAR

Prism is a member of the Confederation of Open Access Repositories (COAR). COAR's mission is to enhance greater visibility and application of research outputs through global networks of Open Access digital repositories. Moreover, COAR aims to enable every citizen in the world to access and benefit from knowledge produced from publicly-funded research.

Notable Submissions.

StatTag Software. StatTag is a free plug-in for conducting reproducible research and creating dynamic documents using Microsoft Word with the Stata and SAS statistical software (future versions will work with R) created by Leah Welty, PhD, Associate Professor of Preventive Medicine (Biostatistics). Dr. Welty used DigitalHub to share a description and a link to the software in GitHub, making her software more discoverable and accessible to users world-wide.

Science in Society. Northwestern’s research center for science education and community engagement created a collection in DigitalHub of award winning scientific images to better connected users with these stunning images.

Pediatric Neurology Briefs. Pediatric Nuerology Briefs is a new collection in DigitalHub, being made available as Open Access (OA) as a continuing education service designed to expedite and facilitate the review of current scientific research and advances in child neurology and related subjects. The DigitalHub team collaborated with the editor and assistant professor of pediatrics and neurology at Feinberg, to host the complete archives.
