Virtual Reality Materials and Experiences
![]() |
||
Virtual reality (VR) refers to a set of technologies which build on existing 3D rendering technologies, with the aim of creating experiences which completely immerse a user in a virtual environment. The related term of Immersive Media (also known by the acronym XR) refers to a set of technologies used to create experiences, which either completely immerse a user in a virtual environment (Virtual Reality), augment the real world with virtual elements (Augmented Reality) or combine elements of the two (Mixed Reality). Key technologies include headsets, tracking systems, real-time 3D software and 360 video. |

‘Critically Endangered’ in the Presence of Aggravating Conditions lack of established frameworks and tools; technology is relatively poorly understood in the digital preservation domain; many of the technologies relied upon are proprietary; technology is seen as inherently fragile and therefore risky to collect and preserve; emulators do not currently support XR applications; expected to be difficult and costly to migrate, a process itself dependent on access to vulnerable source materials. |
||
Vulnerable in the Presence of Good Practice Effective replication; emulation; strong technical documentation; preservation pathway; good descriptive cataloguing; trusted repository. |

2021 Jury Review This was a new 2021 entry submitted through the open nomination process. These VR technologies are finding use in many sectors, including archaeology, architecture, contemporary art, documentary film, gaming, forensics, science and engineering. While these technologies are not new per se, having experienced a first wave in the 1990s, they have experienced renewed interest recently as a result of a new generation of hardware. There are connections between this entry and others relating to both Media Art and Gaming, but it has been included as its own entry to emphasize the issues of preservation that pertain to the interconnected set of specific hardware and software components that access to XR experiences is contingent on. VR is challenging to document due to the individual nature of the experience, and components tend to become rapidly obsolete due to a fast rate of technological change as the industry pushes newer, higher fidelity hardware and software. This results in the potential to lose access to XR software applications, as old VR applications can no longer communicate with new XR hardware. The reliance on proprietary software and hardware components, as well as the lack of industry standards, poses a further risk. |
||
Additional Jury Comments The current wave of materials made using XR technologies represent a unique point in time for the continued development of the technology and therefore represent a significant piece of computing history. Individual materials/experiences created using XR technologies present their own significance beyond this, which, noted elsewhere in this entry, can be represented in a wide range of sectors. The impacts of the loss of access to virtual reality materials could be widely felt, given their wide-ranging uses across many sectors — most notably collections and archives containing materials accessed using these technologies. Simultaneously there is a risk of a loss of understanding of this technologies' development during the 2010-present period, which is likely to be of historical significance in and of itself.

2021 Jury Review In 2019, this entry was added as a subset of a previous 2017 entry, ‘Digital Music Production and Sharing,’ which was split to draw attention to the different challenges faced by the different forms. Though it overlaps with other entries, including ‘Digital Archives of Music Production,’ it is a separate entry to emphasize the inherent and great value of original recordings over and above those distributed and the concomitant need for active preservation. |
||
Additional Comments The imminence of action will depend on format and age, and the significance of loss may be more largely felt if recordings of a major recording star This is interesting as the recording houses should be seeing the value of these - so why are they not taking responsibility for looking after them? Do they not feel it is in their financial interests? The archival practices of the studios are typically based on value - the recordings are assumed to be worth keeping. However, this means relatively low-value original recordings may not be transferred to new media in a timely way and could be lost. There is no comprehensive deposit scheme to address the long tail of music production, and it is often unclear exactly where responsibility lies. Case Studies or Examples:

||
2021 Jury Review When this entry was added in 2017, there was little evidence of any renewed effort to address the issue of orphaned work. While there have been improvements to the baseline competence of the archival and library professions in their understanding of copyright and the skills to preserve contents, this alone provides a narrow basis for optimism and the scale of the challenge is likely to have grown just as quickly if not more so as aggravating conditions become more prevalent too. The 2021 Jury added that while content is preservable, the preservation of orphan works is a matter of process and risk appetite. Added to the complexity are changes to copyright legislation in and across different national and regional contexts, particularly for UK institutions post-Brexit, as noted in the additional comments below. For this reason, there was a 2021 trend towards greater risk. |
||
Additional Comments The Jury would encourage organizations to take a risk-based approach which would help them preserve collections. Copyright infringements are only likely to become a significant issue in the context of access, and in most cases, the likelihood of any specific action is small. Preservation needs to be presented as a social good, one without which copyright holders would simply be unable to benefit from the property rights they seek to protect. For UK institutions, the Jury recommends commentary by Naomi Korn on the status of orphan works and the impact of Brexit - that UK institutions are no longer able to make use of the EU Orphan Works Directive and the alternative Orphan Works Licensing Scheme is costly. A list of resources is available at https://naomikorn.com/resources/. For those in the UK, there is also the UK Copyright and Creative Economy Centre (CREATe) for resources on orphan works and copyright more broadly at https://www.create.ac.uk/resources/.

2021 Jury Review This entry was first introduced in 2017 and noted as being ‘of concern,' though the Jury did not have the capacity to assess the entry thoroughly. Additional expertise was recruited for the 2019 Jury, and the entry was added with the Endangered classification based on the materials not being collected in any coherent way, likely loss when not valued by production companies, costly space needed to hold them, and lack of expertise needed to catalogue and collect them. In other words, this is not primarily a technical problem and advocacy is needed urgently. |
||
Additional Comments With the importance of advocacy in mind, it is important to raise awareness and educate directors and filmmakers about managing their digital archive so that it is still accessible if donated to a cultural institution in the future.

2021 Jury Review This entry was added in 2019 as a subset of an entry made in 2017 for ‘Gaming,’ which the Jury split into four more discrete entries. There are overlaps with the social media entries, except this category specifically draws attention to gaming and e-sports and therefore is a subset of both. By including as a separate entry, the 2019 Jury encouraged greater consideration of the cultural and historic value that such recordings are likely to acquire as well as the technical and economic challenges to preservation. The content is not particularly distinctive in technical terms, but there are aggravating circumstances, namely an almost complete reliance on commercial third parties (Google/YouTube and Amazon/Twitch) for the infrastructure around video capture and hosting. As the majority of this material is experienced and hosted on user-driven and ephemeral platforms such as YouTube and Twitch, it is less 'collectable' than the actual games and is unlikely to exist in private or public collections. Involves platforms that the digital preservation sector does not have much experience working with, e.g., Twitch. For these reasons, the 2021 trend was towards greater risk. |
||
Additional Jury Comments Copyright claims on video content by publishers such as Nintendo - while less prevalent now than a few years ago - also complicate things. The significance of loss here is high because recordings, including commentary, and onscreen interactions with other players, seem likely to be the best way of preserving the experience of playing certain games at certain times. We are familiar with the challenges of preserving video, but we need to think about how established approaches will work in the context of the aggravating circumstances outlined above. There is a degree of urgency associated with working out how (legally and technically) preserving the materials that they hold may be preserved. Important for social context, and from a DP point of view videos should not be too hard, but if we are capturing the experience to inform digital preservation actions and intents, then do not these videos exist in places such as YouTube and wouldn't they be brought in as part of the 'documentary' evidence of DP actions taken on the game or sports that have come into the archive? |

‘Vulnerable’ in the Presence of Good Practice Regular review and testing; replication; refreshment plan; comprehensive documentation; high quality storage; regular maintenance of readers; multiple readers available. |
||
2021 Jury Review This entry was added in 2019 to ensure that the range of media storage is properly assessed and presented. Magnetic media is typically more fragile than optical media because it is susceptible to ‘bitrot’ and magnetic damage in ways that optical media are not. |
||
Additional Comments This entry is highly dependent on who is looking after the portable media but made more difficult over time. The lack of granularity in the definition means that only general advice can be offered, such as to refresh media. In time, it may yet be more useful to split all storage media (maybe 100 items long) with an indication of how long these can be expected to last. In many cases, specialists can recover obsolete media, but the cost of employing them can become an aggravating condition. It is important to emphasize that the short lifetime of many storage devices is not a problem to be solved with new long-lasting storage technologies (and indeed, many inventions have come and gone). Cheap commodity storage has been purposely designed to deliver value at a low price for a short time. Therefore, management and preservation processes for monitoring and refreshment need to take these characteristics into account. |

||
2021 Jury Review The 2019 Jury introduced this entry as a subset of a previous entry for ‘PDF,’ emphasizing the different threats faced by different types of PDF. PDF/A explicitly reduces dependencies and thus curtails preservation risks for certain types of content: PDFs of other types do not. PDF and PDF/A have sometimes been misunderstood as a generic solution to digital preservation requirements. In the Jury’s eyes, it can only offer a preservation solution when embedded within a wider preservation infrastructure. |
||
Additional Jury Comments There is a lot of material produced and kept in PDF. Some of it is authoritative, in other words, the only available copy, while some of it is not. However, if it is the only copy and it is lost, it can have an impact on a lot of people The challenge in evaluating the significance and impact of the loss of PDFs is that they're quite often a surrogate of something else, whether a digitized record or a Word document, etc. Whether or not that record is retained may be a factor. We should also be considering PDF Portfolios, which are an extension of PDF 1.7. Portfolios contain embedded files and can include text documents, spreadsheets, PowerPoints, emails, Computer Aided Design (CAD) drawings. Assessing the risk of this complex format may need to be separate from other PDFs.

2021 Jury Review This entry was added in 2017 as a separate entry due to concern over recordings on LTO tapes. These provide between 15 and 30 years’ storage which may be less depending on usage and storage conditions. LTO1 and LTO2, which were released in 2000 and 2003 respectively, have largely reached the final phases of viability. Reader compatibility may be more problematic than media resilience, however. Drives supporting newer releases of the format are typically only compatible within two generations, and experience with the recently released LTO8 suggests that it is only backwardly compatible to one generation. One major national archive and library for instance had decided to expedite migration away from LTO6, which is becoming obsolete more quickly than anticipated. Through time, the risks to collections that have not been refreshed or replicated from early LTO tapes expand. Thus, the overall trend is towards greater risk when collections are not migrated. Older formats, perhaps as recently as LTO6, extinction events should be anticipated within two to five years. The 2021 Jury agreed with the Endangered classification, noting the importance of a selective approach. |
||
Additional Comments Depending on the legislative context, digital radio recordings may fall under published works if they are broadcasts. Additionally, if the recordings are broadcast by a taxpayer-funded broadcaster, record-keeping guidelines may already exist to advise how long content be kept, which would then inform a selective approach to caring and looking after them for as long as required. While broadcasters may keep their own programmes, they are often not comprehensively collected or archived by memory institutions as contributions to cultural heritage. |

2021 Jury Review This entry is a subset of a previous 2019 entry, ‘Proceedings and Evidence in Court,’ which was itself created as a subset of entry in 2017 for ‘Digital Legal Records and Evidence.’ The 2021 Jury split ‘Proceedings and Evidence in Court’ into two more discrete entries to highlight their distinct preservation challenges and risk profiles. This entry includes court proceedings and recognizes that courts have a responsibility to provide robust preservation that ensures the authenticity of these records. |
||
Additional Comments Standard Records Management processes within designated agencies should be able to take care of the preservation of materials like this but given that evidence is likely to involve complex types of data, such agencies may not be equipped to deliver preservation effectively. It is surprising that courts are not more obvious in the digital preservation community, where solutions now exist. Recordings of proceedings in court may include the AV recording of the court session, which may pose particular preservation risks associated with the video files. |
