Community Standards for 3D Data Preservation

Community Standards for 3D Data Preservation

Last updated on 24 October 2019

Jennifer Moore (Washington University in St. Louis), Adam Rountrey (University of Michigan Museum of Paleontology) and Hannah Scates Kettler (Iowa State University) are Primary Investigators for CS3DP (Community Standards for 3D Data Preservation)


 CS3DP 1

Rapid adoption of new technologies can sometimes result in the creation of vast quantities of poorly documented, at-risk data.  While the immediate advantages of a breakthrough technology such as low-cost 3D scanning or high-speed photogrammetry (creating 3D models from a series of photographs) can quickly lead to widespread use, preservation of the resulting data is often overlooked and only considered when the stacks of external drives in the closet are starting to fall over.  Indeed, several years ago, we found ourselves wondering if others were eyeing their rapidly accumulating 3D data with similar anxiety, and in 2017, we decided to conduct a survey targeted at those creating, using, and curating 3D data in various fields to find out. Most responses came from individuals at universities, libraries, and museums in the United States, and the majority of respondents were, as we suspected, not using documented best practices or standards for handling 3D data.  Those who were had largely developed their own standards in house. Of those not using standards/best practices, 69% said that they did not use them because they were unaware of such standards. However, the vast majority (85%) of all respondents said they would like to develop standards and best practices collaboratively as a community.  Survey comments, such as, “I am very excited to see that you are doing this survey and potentially pulling this community together,” from an expert at a leading museum captured the desire for progress in the area as well as the sense that successful standards development would require participation from diverse stakeholders.  These results led to the development of the Community Standards for 3D Data Preservation (CS3DP) program.

As a consultant with AVP, I work with many different types of organizations to help them assess and optimize their digital preservation programs. I have the opportunity to really dig into the inner workings of these digital preservation environments. I've found that it is very common for institutions to have very little documentation relating to their digital preservation programs. Sure, you know what you're doing, but there are so many other reasons to create documentation!

Brian Lavoie is Research Scientist for OCLC in the USA


An important class of at-risk digital materials is the myriad forms of output generated over the research lifecycle – think of data sets, computer code, online discussions, e-lab notebooks, and so on. Growing recognition of the value of these materials to the scholarly record has led to many efforts to collect and preserve them over the long term. But mitigating risks associated with preserving digital research outputs means setting up stewardship arrangements that are well-adapted to the evolving nature of today’s scholarly record. For that, we need stewardship with a network logic, or conscious coordination.

Online web services are used by billions of people every day. They impact our lives and society in a myriad of ways. The way they present data to us and the ways they manipulate and transform the data we store in them have the potential to change behaviour and our understanding of the world. And this is all being done at a scale unimaginable in previous history.  These services have changed greatly over time. Many of those changes are not publicly documented or even known to the general public. I’ve outlined a few of those we do know of below:

Preserving and Integrating Community Knowledge of Computing Systems

The efforts of the EaaSI (Emulation-as-a-Service Infrastructure) project and the Software Preservation Network to preserve the software and computing environments around digital objects have revealed that a parallel effort needs to be made to preserve the expertise and knowledge necessary to use and interact with such environments. Scanning software manuals and printed guidebooks, photographing boxes and physical media, archiving the web sites of developers, enthusiasts and community forums - all of these are necessary activities, largely happening on an ad hoc basis in the digital preservation community if at all. Dedicated, collaborative initiatives on this front are essential to make sure future users are able to interact with authentic digital objects in context.

One of the student workers we employ in the EaaSI program once came to me with a troubleshooting problem. This is not unusual - our diligent student team is tasked with cataloging and attempting to install a vast range of legacy software applications, and between quirks in the applications, quirks in the necessary operating systems, quirks in the emulators running them and quirks in Yale’s beta installation of the EaaSI platform, any number of questions can come up. The student was having trouble with an application running in MacOS 7.5: the menu bar at the top of the screen seemed to be glitching, constantly closing before they could access the settings and preference menus that are often our best source of information about a given piece of software (language configuration, file format capabilities, etc.)

Sally McInnes is Chair of the ARCW Digital Preservation Group and Head of Unique Collections and Collections Care at the National Library of Wales


It has been two years since the Archives and Records Council launched its National Digital Preservation Policy on International Digital Preservation Day, 2017.  Since then, ARCW has made considerable progress in supporting the policy, the aims of which are to:

  • To ensure digital resources of enduring value are selected for preservation and remain authentic and accessible in the future.
  • To provide a framework for the development of digital preservation strategies that can be adapted for use by organisations throughout Wales, irrespective of their size and capacity.
  • To raise awareness of the importance of effective Digital Preservation among archive institutions and practitioners, managers, information technology staff and stakeholders / decision makers.

Email at Risk: Challenges and Opportunities in Preserving Email

Email offers singular insight into and evidence of a person or organization’s self-expression, as well as records of collaboration, professional, social, and familial networks, and all manner of transactions. Email is an essential component of the archival record -- the modern equivalent of the type or hand-written correspondence of past centuries. However, email is also a complex format that poses many technical challenges to archivists working to preserve and provide access to it. In their 2018 report, the Task Force on Technical Approaches for Email Archives described email as, “…not one thing, but a complicated interaction of technical subsystems for composition, transport, viewing, and storage.”

Compounding this complexity, email is not a constant or consistent format. As email technology has evolved and email clients have fallen in and out of use, archivists working with historical email collections will encounter a wide variety of email file types. Thus, the most essential tasks of capturing, processing, preserving, and providing access to email pose a host of technical obstacles for cultural heritage institutions.

3D content, both digitized and born-digital, continues to be an area of focus across the Library of Congress. Last year on the #WDPD blog, we focused on a recap of the Born to Be 3D: Digital Stewardship of Intrinsic 3D Data (#B2B3D) small group forum to discuss stewardship of born digital 3D data. This year on the Sustainability of Digital Formats website, we’re diving a bit more in depth to explore file formats for 3D for scanning, printing and modeling.

This year for World Digital Preservation Day I decided to focus on the place of games in digital preservation. The digital preservation community benefits from having digital preservation games to help build understanding and awareness about good practice for digital preservation games also represent an example of complex digital content that may need to be preferred. I have been lightly monitoring a class on game design this semester as a way to continue thinking about games in the various ways digital preservation intersects with them.

Taming the Pre-Ingest Processing Monster

We hear again and again that, first, one of the biggest threats to ensuring long-term access to our digital heritage is the cost of preservation, and, second, that one of the critical cost drivers is the set of activities associated with selection, acquisition, and other pre-ingest processing (such as quality assurance of acquired artifacts). 

As the amount of content in preservation archives grows at geometric rates, and as the artifacts in ever-increasing input streams continues to evolve, sometimes unpredictably, into varying new complex forms, how do we scale what might be called “pre-ingest” activities without scaling up our costs at the same rate?
