The cornerstone of digital preservation, "data integrity" refers to the assurance that the data is "complete and unaltered in all essential respects"; a program designed to maintain integrity aims to "ensure data is recorded exactly as intended, and upon later retrieval, ensure the data is the same as it was when it was originally recorded".
Although digitization seems to be a promising area for future preservation, there are also problems. The main problems are that digital space costs money, media and file formats may become obsolete, and backwards compatibility is not guaranteed. [5] Higher-quality images take a longer time to scan, but are often more valuable for future use.
PDF is a standard for encoding documents in an "as printed" form that is portable between systems. However, the suitability of a PDF file for archival preservation depends on options chosen when the PDF is created: most notably, whether to embed the necessary fonts for rendering the document; whether to use encryption; and whether to preserve additional information from the original document ...
In 2014, the National Digital Stewardship Alliance recommended developing file format action plans, stating "it is important to shift from more abstract considerations about file format obsolescence to develop actionable strategies for monitoring and mining information about the heterogeneous digital files the organizations are managing".

Rhizome operates a digital preservation program, led by Dragan Espenschied, which is focused on the creation of free, open source software tools to decentralize web archiving and software preservation practices and ensure access to its collections of born-digital art. Oldweb.Today and Webrecorder are its tools focused on web archiving specifically.

The term "digital curation" is sometimes used interchangeably with terms such as "digital preservation" and "digital archiving." [2] [16] While digital preservation does focus a significant degree of energy on optimizing reusability, preservation remains a subtask to the concept of digital archiving, which is in turn a subtask of digital curation.
A SIARD file incorporates both the database content and also machine-processable structural metadata that records the structure of database tables and their relationships. The ZIP file contains an XML file describing the database structure (metadata.xml) as well as a collection of XML files, one per table, capturing the table content.
