Digital preservation is fundamental to information stewardship in the 21st century. Although much useful work on preservation strategies has been accomplished, we do not yet have an adequate conceptual framework that articulates precisely and formally what preservation actually is. The intention of the account provided here is to bring us closer to this goal. Following an initial analysis of the concept of preservation as it occurs in ordinary discourse around digital stewardship, several influential preservation models are analyzed, identifying both useful insights and problems.
Libraries and archives at Harvard hold thousands of unique items across hundreds of digital formats, including aging technology such as CDs, floppy disks, tapes, and cassettes. To retrieve content prior to total obsolescence or decay of digital formats, librarians are using digital forensic software commonly employed by the police or the FBI to solve crimes, which enables them to identify content noninvasively and migrate it to a more stable platform.
Known for their active community and catchy slogans, Archivematica is a “web- and standards-based, open-source application which allows your institution to preserve long-term access to trustworthy, authentic and reliable digital content.”

The Database Preservation Toolkit uses input and output modules and allows conversion between database formats, including connection to live systems. It allows conversion of live or backed-up databases into preservation formats such as DBML, SIARD, or XML-based formats created for the purpose of database preservation.
This toolkit was part of the RODA project and now has been released as a separate project. The site includes download links and related publications and presentations.

The advantage of blogs compared with such talks is that here, discussions can happen across geographical and temporal borders, and that they stay visible online in comments or companion posts. But aren't blog posts, ultimately, almost as fleeting as a talk at a workshop? Who makes sure the content stays online not just today and tomorrow, but in the long term? Who guarantees that the link to the post remains the same? Who ensures that the text will not be modified later on?
The prototyping phase of the public pre-commercial procurement project PREFORMA started on April 14th 2015, with the announcement of the three winners.
The aim of PREFORMA is to develop an open-source toolset for the conformance checking of digital files intended for long-term preservation in memory institutions.
After analysing the technical and functional specifications submitted by the six groups that completed the design phase in March 2015, PREFORMA chose the three consortia awarded with contracts for the prototyping phase. This phase will last until December 2016.
As has been famously outlined by the Library of Congress on their website on sustainability factors for digital formats, digital material is just as susceptible to obsolescence as analog formats. Within digital preservation there are a number of strategies that can be employed in order to protect your data including refreshing, emulation or migration, to name a few. As the National Digital Stewardship Resident at Harvard Library, I am responsible for developing a format migration framework which can be continuously adapted for migration projects at Harvard.
ecently on Inside/Out, we heard from Assistant Media Conservator Peter Oleksik about MoMA’s efforts to preserve and digitize its collection of analog video art, amassed over the course of four decades. The heroic undertaking of digitizing over 4,000 videotapes was absolutely critical for preservation and access purposes. However, when we digitize analog videotape, we have just begun a new chapter in the artwork’s life, one that is rife with grave challenges and risks that are unique to digital materials.
When Kathleen O’Neill talks about digital collections, she slips effortlessly into the info-tech language that software engineers, librarians, archivists and other information technology professionals use to communicate with each other. O’Neill, a senior archives specialist in the Library of Congress’s Manuscript Division, speaks with authority about topics such as file signatures, hex editors and checksums even though she has a traditional paper-centric Master of Library Science degree.
