ABOUT
The Marriott Reparative Metadata Assessment Tool (MaRMAT) is an open-source application created by librarians at the University of Utah’s J. Willard Marriott Library to help metadata practitioners flag various terms and phrases within metadata records using pre-curated and custom lexicons. MaRMAT is schema agnostic and supports library and museum professionals in assessing metadata for harmful, outdated, and otherwise problematic language in tabular metadata. In addition to reparative work, MaRMAT can be used to support broader metadata assessment and collections content analysis.
Identifying potentially harmful language—including problematic or outdated Library of Congress Subject Headings—is one important step toward reparative metadata practices. However, deciding what to change and how to change it requires thoughtful judgment by metadata practitioners. This work calls for awareness, education, and sensitivity to the communities and histories represented in digital collections. The Inclusive Metadata Toolkit, created by the Digital Library Federation’s Cultural Assessment Working Group, offers valuable resources to support decision-making in reparative metadata work.
MaRMAT was inspired by Duke University’s Description Audit Tool, developed to analyze MARC XML and EAD finding aid metadata. We created MaRMAT to complement this work by enabling bulk analysis of metadata in tabular formats, allowing for schema-agnostic assessment.
