What is Fixity and Why is it Important?

Fixity monitoring and reporting is a practice that every digital preservation and data integrity expert in the world agrees on as being foundational and critical. From the National Digital Stewardship Alliance and the Digital Library Federation to the International Organization on Standardization, and from the Digital Preservation Coalition to the Library of Congress. Despite this fact, for a variety of reasons ranging from technical know-how to funding, many organizations and individuals have historically not been able to perform this fundamental practice. It has only been available to larger, well-resourced organizations with technical expertise, infrastructure, and funding. Fixity Pro aims to democratize this practice, bringing a simple, low-cost solution to individuals and large organizations alike – enabling everyone to practice data integrity like a pro.
