Significance of Loss

The loss of tools, data or services within this group would impact on many people and sectors.

Effort to Preserve

It would require a major effort to prevent losses in this group, including the development of new preservation tools or techniques

Examples

USB sticks and pen drives; Flash storage in cameras and phones; certain types of portable hard disk

‘Practically Extinct’ in the Presence of Aggravating Conditions

Poor physical storage; inability to access readers; no replication; encryption

‘Endangered’ in the Presence of Good Practice

Active management; dependable access to readers; strong documentation; documentation independent from the media

2019 Review

The judges have introduced this entry to ensure that the range of media storage is properly assessed and presented.  Solid state media – typically flash – provides very fast access to data but can fail without warning.  This is because it is typically subject to a limited number of program/erase cycles, as well as ‘read/disturb’ effects. Storage at scale also means the percentage likelihood of failure increases. 

Additional Jury Comments

Early generations of media and cheap giveaways are not robust and can deteriorate significantly over time.

‘Endangered’ in the Presence of Good Practice

Active management; dependable access to readers; strong documentation; documentation independent from the media

2019 Review

The judges have introduced this entry to ensure that the range of media storage is properly assessed and presented.  Optical media is in some senses a preferred option as it is typically more stable than magnetic or solid state media: but these characteristics have been over-sold.  The substrates of the disks can prove unstable and more importantly the reader technology tends to be proprietary and can become obsolete long before the disks degrade. Storage at scale also means the percentage likelihood of failure increases.

Additional Jury Comments

Highly dependent on who is looking after the portable media but made more difficult over time. There is a lack of granularity in the definition of media types so generic advice like "make sure you're moving your data to new forms of storage every 5 -10 years".

Early generations of this media are not as robust as the current generation and can deteriorate significantly if not stored appropriately.

Significance of Loss

The loss of tools, data or services within this group would impact on many people and sectors.

Effort to Preserve

It would require a major effort to prevent losses in this group, including the development of new preservation tools or techniques

Examples

Floppy disks; tape; certain kinds of portable hard disks, zipdrives.

‘Practically Extinct’ in the Presence of Aggravating Conditions

Poor storage; inability to access readers; no replication; encryption; aggressive compression

‘Endangered’ in the Presence of Good Practice

Active management; dependable access to readers; strong documentation; documentation independent from the media

2019 Review

The judges have introduced this entry to ensure that the range of media storage is properly assessed and presented.  Portable magnetic media was ubiquitous but is fragile not just to physical wear and tear but also to magnetic interference and bit-rot.  The substrates of the disks can prove unstable and in some cases proprietary reader technology means that the disk becomes obsolete before it degrades. Storage at scale also means the percentage likelihood of failure increases

Additional Jury Comments

There is really no excuse for using floppy disks for storage these days.  Tape is a different proposition since it allows high-density back up offline and nearline.  But there are challenges with backwards compatibility of popular and even relatively recent LTO versions.

Significance of Loss

The loss of tools, data or services within this group would impact on people and sectors around the world.

Effort to Preserve

It would require a small effort to prevent losses in this group, such as the deployment of proven preservation tools or techniques

Examples

Disks installed into computers or servers that are more than fives years old, or out of warranty

‘Practically Extinct’ in the Presence of Aggravating Conditions

Lack of replication; poor storage; non-standard connections or controllers; aggressive compression; encryption

‘Endangered’ in the Presence of Good Practice

Maintenance schedule; renewable extendable warranty; best practice storage and operation; replication

2019 Review

The judges have introduced this entry to ensure that the range of media storage is properly assessed and presented.  The lifecycles of most consumer hard disk technology is stable in comparison to portable devices because they are integrated into systems and therefore inherit the lifecycle and replacement of the entire system.  This is less true at scale however where disks are used in storage arrays and refreshment is more loosely tied to the server architecture.  Storage at scale also means the percentage likelihood of finding a disk failure increases.

Additional Jury Comments

Perversely the greater density of newer disks, as well as encryption and compression mean that they can be more fragile than older disks with less density and less sophisticated read/write technologies.  The age of a disk is not the best or only indicator of its reliability.

Examples

Flash based games; Flash cartoons; Flash interactives

‘Practically Extinct’ in the Presence of Aggravating Conditions

Dependence on older (unpatched) versions of Flash Player; lack of migration pathway to HTML5 or cognate technology; lack of capacity or motivation to export; execution in older browsers.

‘Endangered’ in the Presence of Good Practice

Migration plan initiated; supported in multiple browsers; security vetted

2019 Review

This is a new entry received from the Open submission process and reviewed by the Jury.  Flash animations and applets was a mainstay of interactive web design from the late 1990’s. Flash anmimation and interactives are created using tools supplied by the Adobe of the same name.  Although Flash enables the development of sophisticated interaction at low cost over the web, it has had a chequered history in terms of browser support and has been plagued by security concerns.  It is due to be retired by December 2020 and publishers are being encouraged to migrate to alternative formats. 

Additional Jury Comments

Flash represents a significant amount of the creativity of websites in the early 2000’s including net-based art and cartoons.

Extinction is imminent for flash viewers: web archives will need to consider if it is possible to preserve interaction in newer browsers, or rely on a much more highly selective WebRecorder approach.

Media Art by deceased artists or defunct workshops

   Critically Endangered small

Media art where the artists or creative technicians are either deceased or not able to provide guidance on authenticity and installation

Imminence of Action

Action is recommended within twelve months, detailed assessment is now a priority

Significance of Loss

The loss of tools, data or services within this group would impact on people and sectors around the world.

Effort to Preserve

Loss seems likely: by the time tools or techniques have been developed the material will likely have been lost.

Examples

Works produced by media artists now deceased, such as: Jeremy Blake, Beatriz Da Costa, Heiko Daxl or Stanislaus Ostoja-Kotkowski.

‘Practically Extinct’ in the Presence of Aggravating Conditions

Lack of documentation to enable maintenance; lack of clarity with respect to intellectual property; complex interdependencies on specific hardware, software or operating systems; lack of capacity in the gallery or workshop; lack of strategic investment; complex external dependencies; loss of institutional memory resulting from staff churn; poor working relationship between the gallery and artist/workshop; lack of conservation assessment.

‘Endangered’ in the Presence of Good Practice

Strong documentation; clarity of preservation path and ensuing responsibilities; proven preservation plan; capacity of workshop to support re-installation; capacity of gallery to conserve; capacity of gallery to re-install; retention of institutional memory including archives of correspondence between gallery and artist/workshop; strong and continuing working relationship between the gallery and artist/workshop; regular conservation assessment.

2019 Review

Media Art was introduced in 2017, though with particular reference to historical media art which was categorised as ‘critically endangered’. The jury has split this to ensure greater specificity in its recommendation.  This entry represents works held in galleries where the artist is deceased or the workshop has closed and there is limited prospect to obtain new documentation.

Additional Jury Comments

This entry includes a point in the lifecycle of all media art so good practice recommendations are likely to become more important over time.

Preservation issues may not become visible until the piece is brought out of storage for loan or exhibition, underscoring the value of continuous or periodic conservation assessment.

The range of data/formats/hardware/software etc. can be new and varied providing organisations with an ongoing technical challenge which they are not initially equipped to deal with. Some loss seems inevitable.

‘Practically Extinct’ in the Presence of Aggravating Conditions

Poor documentation; lack of preservation mandate; dependence on proprietary and non-standard data types

‘Endangered’ in the Presence of Good Practice

Preservation planning from the outset; subject specialist repository; user community

2019 Review

This is a new entry taken from the open submission process in 2019.  It is grouped with Museum data sets as archaeological archives typically make their way to museums, but it is also closely aligned to research data.

Additional Jury Comments

There are trusted custodians of this data such as ADS, DANS or the British Museum as well as in oceanographic research agencies, but perhaps hard to integrate good practice at an international scale. The real challenge therefore is in identifying and sustaining a custodian as other bodies have experience with this data. The proliferation of innovative data recording technologies also implies likely problems of format dependence and documentation.

‘Practically Extinct’ in the Presence of Aggravating Conditions

Inaccessible to web archive; bespoke code; insufficient documentation; uncertain intellectual property right.

‘Endangered’ in the Presence of Good Practice

Secured by web archive; documentation and rights information published alongside

2019 Review

This is a new entry received from the open submission process and assessed by the Jury.  It has an overlap with the entry with ‘Semi-Published Research’ Data’ which was classified as ‘Endangered’.  The Jury has approved this entry as a means of distinguishing ‘current’ and ‘legacy’ collections: and in this case the fact that materials are no longer actively maintained means that the risks of loss are greater.

Additional Jury Comments

The Internet Archive and other national web archiving bodies have copies of a lot of websites which would fit into this category, but by no means all. There’s also a distinction between the software or code used to deliver the user experience and the data.  Such code is secondary to the content.

‘Endangered’ in the Presence of Good Practice

Use of persistent identifiers; embedded within repository infrastructure; quality assurance

2019 Review

Research data has been an entry in the BitList since 2017 so the Jury this year has tried to spell out the different complexities that arise in the preservation of research outputs more generally.  This entry represents activities which build towards formal publications and research outputs but which do not typically accumulate in institutional repositories. 

Additional Jury Comments

Loss of material like this would be common in the analogue world, but in the digital age we have the capacity and perhaps something of a responsibility to ensure that it is captured: more of an opportunity lost to extend the available research resource.  The ADS’s Grey Literature Library demonstrates what could be done if information architectures are deployed to mirror and extend professional practice.

Workflows and policies re tagging, collecting and EDRMS may help protect such data into the future. Past materials are almost certainly partially lost

Significance of Loss

The loss of data, tools or services within this group would have a localised impact.

Effort to Preserve

Examples

childhood photographs and videos; School or graduation photos; wedding photos and movies; electronic correspondence (email, messenger, WhatsApp)

‘Practically Extinct’ in the Presence of Aggravating Conditions

storage on portable media or poor storage; dependence on devices or processes; dependence on obsolete or proprietary formats; storage media out of warranty; single copies; inappropriate dependence on service provider; inappropriate encryption or password protection; lack of awareness or planning; loss or lack of documentation; over-abundance; inability to act in a timely manner; confusion over intellectual property

‘Endangered’ in the Presence of Good Practice

Replication; action in a timely manner; open formats; selection and appraisal; archival agency

2019 Review

This was introduced to the BitList in 2017.  Although research and advice on preservation of personal records have been available for some time, outreach and training has not reached the audience and there has been no material improvement in the risks faced by this category since 2017.  It is reasonable to assume that the number of digital objects in this category has increased thus the consequences of loss have expanded. 

It is also a very large category and may be usefully broken into a series of components to represent the complexity more effectively and present a more nuanced action plan.

Additional Jury Comments

A strong overlap with community archives, except noting that responsibility is even more localised. Some loss is inevitable.

This matter needs awareness raising. Education is needed, such as digital preservation as a survival skill for teenagers. Also simple and cheap tools or pathways to preservation are needed.
