PRONOM is a web-based technical registry to support digital preservation services, developed by The National Archives of the United Kingdom. PRONOM was the first and remains, to date, the only operational public file format registry in the world,〔(【引用サイトリンク】title=Excuse Me... Some Digital Preservation Fallacies? )〕〔(Van Wijngaarden, H. (2005) Format Registries, ''CASHMERE-int Workshop on Preservation and DC-tools: Standards and standardization activities, Goettingen'': 6 )〕 although the "Magic File" repository of the File Command has served this role in a less formal capacity for two decades. Other projects to develop technical registries, including the UK Digital Curation Centre's Representation Information Registry, and the Global Digital Format Registry project at Harvard University, are now in progress. PRONOM's origins lie in a requirement to have access to reliable technical information about the electronic records held by The National Archives. By definition, electronic records are not inherently human-readable - file formats encode information into a form which can only be processed and rendered comprehensible by very specific technological environments. The accessibility of that information is therefore highly vulnerable to technological obsolescence. Technical information about the structure of those file formats, and the software and hardware environments required to support them, is therefore a prerequisite for any digital preservation regime.〔(【引用サイトリンク】title=Contents )〕 PRONOM was developed to provide this function, initially as an internal resource for National Archives staff, and subsequently as public, web-based resource. == Development == The first version of PRONOM was developed by The National Archives digital preservation department in March 2002. PRONOM 2 was released in December 2002, and provided support for the development of multi-lingual versions of the registry. The web-enabling of PRONOM (PRONOM 3) in February 2004 represented the starting point for the development of PRONOM as a major online resource for the international digital preservation community.〔(【引用サイトリンク】title=OCLC: Worldwide, member-owned library cooperative - Global )〕 PRONOM 4, released in October 2005, includes a significant reworking of the underlying data model to allow the capture of detailed technical information on file formats and support future interoperability with other planned registry systems, and the release of the DROID software for automatic file format identification. The latest version PRONOM 5 was a relatively minor update to support improvements to DROID and was released in 2006. A much more substantial update is planned for 2007, which will include the exposure of core PRONOM functions through web services interfaces. This work forms part of the Seamless Flow programme to position The National Archives to receive and manage future government records in electronic formats. In future, PRONOM may participate as a node in the planned Global Digital Format Registry project. The National Archives won the 2007 Digital Preservation Award sponsored by the Digital Preservation Coalition, for its work on PRONOM and DROID.〔(【引用サイトリンク】title=404 - Digital Preservation Coalition )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PRONOM」の詳細全文を読む スポンサード リンク
