digital documents stripped them of their inherent "digital" qualities, including machine readability and dynamic, user functionalities. Computer museums were also cited as an inadequate practice. There are practical limitations of a limited number of locations capable of maintaining obsolete hardware forever, realistically limiting the full access capabilities of legacy digital documents: additionally, most older data rarely exists in coding formats to take full advantage of their original hardware or software environments. Two digital preservation processes specifically criticized were the implementation of relational database (RDB) standards and an overreliance on migration. While designed for standardization, RDBs and the features of their management systems (RDBMS) often promoted unintentional tribalistic practices among regional institutions, introducing incompatibilities between RDBs: meanwhile, the ubiquity of file and program migration frequently risked failing to compensate for conversional paradigm shifts between increasingly newer software environments. Emulation, with the digital data supported by an encapsulation of metadata, documentation, and software and emulation environment specifications, was argued as the most ideal preservation practice in the face of digital obsolescence.

Such steps run the gamut from enforcing responsibility of information continuity and confirming the degree of content metadata, to ensuring critical information discovery through institutional usage and that system migration doesn’t affect information accessibility, to guaranteeing IT support and enforcing contingency plans for information survivability through organizational changes.

dust and grime. Routine maintenance, calibrations, and cleaning operations can help extend the lifetime of many devices, but broken or failing parts will need repair or replacement: sourcing parts becomes more difficult and expensive as the supply stock for older machines reaches scarcity, and user technical skills grow challenged as newer machines and storage formats use less electromechanical parts and more integrated circuits and other complex components.
