and Eric Freeman. Domesday86 Subsequent efforts by the Domesday86 project have taken a broader approach to preservation by attempting to preserve the technologies used to access Domesday and other interactive video content, along with the content itself, focusing on the laserdiscs as preservation artefacts in their own right. The stated objective of the group is to create hardware and software to permit the use of the BBC Domesday system without the need for the rare and expensive specialist hardware employed by the original system, also providing support for the original hardware, releasing developments under Free Software and open hardware licences. Museum preservation initiatives The Centre for Computing History has undertaken a similar project to preserve the data from the Domesday Project and made it available online. In 2011, with the National Disc and Community Disc processed, the museum was investigating copyright issues before releasing the URL to the general public. An emulator has since been made available in collaboration with the Domesday86 project. The museum has a working Domesday system on display and accessible to the public. They also have possibly the largest Domesday and interactive laserdisc archive in the world. The National Museum of Computing based beside Bletchley Park in Milton Keynes previously had two working Domesday systems but has retired the displays as of 2017. Archival of material The deputy editor of the Domesday Project, Mike Tibbets, has criticised the UK's National Data Archive to which the archive material was originally entrusted, arguing that the creators knew that the technology would be short-lived but that the archivists had failed to preserve the material effectively. Language and regional issues An initial decision to only support the entry of text in English for the Domesday discs led to a dispute involving Welsh schools in areas where local education authorities supported both English and Welsh as first languages: A compromise saw the BBC allowing ten pages of Welsh text that were to be accompanied by ten pages of English translation for each school submitting content in the Welsh language. With such schools effectively seeing their allocation being reduced from twenty pages to ten, some Welsh schools were apparently boycotting the project in protest at this apparent discrimination. Other concerns from Welsh schools were raised in relation to featured amenities to be surveyed by each school, these being less commonplace in rural areas, suggesting a bias towards urban areas in the design
