Digital Preservation
In library science, library and archival science, digital preservation is a formal process to ensure that digital information of continuing value remains accessible and usable in the long term. It involves planning, resource allocation, and application of Preservation (library and archive), preservation methods and Technology, technologies,Day, Michael. "The long-term preservation of Web content". Web archiving (Berlin: Springer, 2006), pp. 177-199. . and combines policies, strategies and actions to ensure access to digital reformatting, reformatted and "born-digital" content, regardless of the challenges of media failure and technological change. The goal of digital preservation is the accurate rendering of authenticated content over time.Evans, Mark; Carter, Laura. (December 2008). The Challenges of Digital Preservation.

Digital Reformatting
Digitization is the process of converting information into a Digital data, digital (i.e. computer-readable) format.Collins Dictionary. (n.d.). Definition of 'digitize'. Retrieved December 15, 2021, from https://www.collinsdictionary.com/dictionary/english/digitize The result is the representation of an object, image, sound, document, or Signal (electrical engineering), signal (usually an analog signal) obtained by generating a series of numbers that describe a discrete set of points or Sample (signal), samples. The result is called ''Digital data, digital Group representation, representation'' or, more specifically, a ''digital image'', for the object, and ''digital form'', for the signal. In modern practice, the digitized data is in the form of binary numbers, which facilitates processing by digital computers and other operations, but digitizing simply means "the conversion of analog source material into a numerical format"; the decimal or any other number system can be used i ...

Library Science
Library and information science (LIS)Library and Information Sciences is the name used in the Dewey Decimal Classification for class 20 from the 18th edition (1971) to the 22nd edition (2003). are two interconnected disciplines that deal with information management. This includes organization, access, collection, and regulation of information, both in physical and digital forms.Coleman, A. (2002)Interdisciplinarity: The Road Ahead for Education in Digital Libraries D-Lib Magazine, 8:8/9 (July/August). Library science and information science are two original disciplines; however, they are within the same field of study. Library science is applied information science. Library science is both an application and a subfield of information science. Due to the strong connection, sometimes the two terms are used synonymously. Definition Library science (previously termed library studies and library economy) is an interdisciplinary or multidisciplinary field that applies the practices, per ...

Fonds
In archival science, a fonds (plural also ''fonds'') is a group of documents that share the same origin and have occurred naturally as an outgrowth of the daily workings of an agency, individual, or organization. An example of a fonds could be the writings of a poet that were never published, or the records of an institution during a specific period. Fonds are a part of a hierarchical level of description system in an archive that begins with fonds at the top. Subsequent levels become more descriptive and narrower as one goes down the hierarchy. The level descriptions go from fonds to series to file and then item level. Between the fonds and series level there is sometimes a sub-fonds () level, and between the series and file level there is sometimes a sub-series level. Historical origins In the archival science field, it is widely agreed upon that the term ''fonds'' originated in French archival practice shortly after the French Revolution as , head of the Administrative S ...

Uffington White Horse
The Uffington White Horse is a Prehistoric Britain, prehistoric hill figure, long, formed from deep trenches filled with crushed white chalk. The figure is situated on the upper slopes of Whitehorse Hill in the English civil parishes in England, civil parish of Uffington, Oxfordshire, Uffington in Oxfordshire, some east of Swindon, south of the town of Faringdon and a similar distance west of the town of Wantage; or south of Uffington. The hill forms a part of the scarp of the Berkshire Downs and overlooks the Vale of White Horse to the north. The best views of the figure are obtained from the air, or from directly across the Vale, particularly around the villages of Great Coxwell, Longcot, and Fernham. The Uffington White Horse was created some time between 1380 and 550 , during the late Bronze Age or early Iron Age. The site is owned and managed by the National Trust for Places of Historic Interest or Natural Beauty, National Trust and is a scheduled monument. ''T ...

Interoperability
Interoperability is a characteristic of a product or system to work with other products or systems. While the term was initially defined for information technology or systems engineering services to allow for information exchange, a broader definition takes into account social, political, and organizational factors that impact system-to-system performance. Types of interoperability include syntactic interoperability, where two systems can communicate with each other, and cross-domain interoperability, where multiple organizations work together and exchange information. Types If two or more systems use common data formats and communication protocols then they are capable of communicating with each other and they exhibit ''syntactic interoperability''. XML and SQL are examples of common data formats and protocols. Low-level data formats also contribute to syntactic interoperability, ensuring that alphabetical characters are stored in the same ASCII or a Unicode format in all ...

Checksum
A checksum is a small-sized block of data derived from another block of digital data for the purpose of detecting errors that may have been introduced during its transmission or storage. By themselves, checksums are often used to verify data integrity but are not relied upon to verify data authenticity. The procedure which generates this checksum is called a checksum function or checksum algorithm. Depending on its design goals, a good checksum algorithm usually outputs a significantly different value, even for small changes made to the input. This is especially true of cryptographic hash functions, which may be used to detect many data corruption errors and verify overall data integrity; if the computed checksum for the current data input matches the stored value of a previously computed checksum, there is a very high probability the data has not been accidentally altered or corrupted. Checksum functions are related to hash functions, fingerprints, randomization functio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File Fixity
File fixity is a digital preservation In library science, library and archival science, digital preservation is a formal process to ensure that digital information of continuing value remains accessible and usable in the long term. It involves planning, resource allocation, and appli ... term referring to the property of a digital file being fixed, or unchanged. Fixity checking is the process of verifying that a digital object has not been altered or corrupted. During transfer, a repository may run a fixity check to ensure a transmitted file has not been altered en route. Within the repository, fixity checking is used to ensure that digital files have not been affected by data rot, or other digital preservation dangers. By itself, fixity checking does not ensure the preservation of a digital file. Instead, it allows a repository to identify which corrupted files to replace with a clean copy from the producer or from a backup. In practice, a fixity check is most often accomplished ...

Data Integrity
Data integrity is the maintenance of, and the assurance of, data accuracy and consistency over its entire Information Lifecycle Management, life-cycle. It is a critical aspect to the design, implementation, and usage of any system that stores, processes, or retrieves data. The term is broad in scope and may have widely different meanings depending on the specific context even under the same general umbrella of computing. It is at times used as a proxy term for data quality, while data validation is a prerequisite for data integrity. Definition Data integrity is the opposite of data corruption. The overall intent of any data integrity technique is the same: ensure data is recorded exactly as intended (such as a database correctly rejecting mutually exclusive possibilities). Moreover, upon later Data retrieval, retrieval, ensure the data is the same as when it was originally recorded. In short, data integrity aims to prevent unintentional changes to information. Data integrity is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard (warez)
The Warez scene, often referred to as The Scene, is an underground network of piracy groups specialized in obtaining and illegally releasing digital media before their official release date. The Scene distributes all forms of digital media, including computer games, movies, TV shows, music, and pornography. This network is meant to be hidden from the public, with the files shared only with members of the community. However, as files became commonly leaked outside the community and their popularity grew, some individuals from The Scene began leaking files and uploading them to file-hosts, torrents and EDonkey Networks. The Scene has no central leadership, location, or other organizational culture. The groups themselves create a rule set for each Scene category (for example, MP3 or TV) that then becomes the active rules for encoding material. These rule sets include a rigid set of requirements that Warez groups (shortened as "grps") must follow in releasing and managing materi ...

Filename
A filename or file name is a name used to uniquely identify a computer file in a file system. Different file systems impose different restrictions on filename lengths. A filename may (depending on the file system) include: * name – base name of the file * Filename extension, extension – may indicate the File format, format of the file (e.g. .txt for plain text, .pdf for Portable Document Format, .dat for unspecified binary data, etc.) The components required to identify a file by utilities and applications varies across operating systems, as does the syntax and format for a valid filename. The characters allowed in filenames depend on the file system. The letters A–Z and digits 0–9 are allowed by most file systems; many file systems support additional characters, such as the letters a–z, special characters, and other printable characters such as accented letters, symbols in non-Roman alphabets, and symbols in non-alphabetic scripts. Some file systems allow even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metadata
Metadata (or metainformation) is "data that provides information about other data", but not the content of the data itself, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, and permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of Statistical data type, statistical data. * Statistical metadata – also called process data, may ...

Identifier
An identifier is a name that identifies (that is, labels the identity of) either a unique object or a unique ''class'' of objects, where the "object" or class may be an idea, person, physical countable object (or class thereof), or physical mass noun, noncountable substance (or class thereof). The abbreviation ID often refers to identity, identification (the process of identifying), or an identifier (that is, an instance of identification). An identifier may be a word, number, letter, symbol, or any combination of those. The words, numbers, letters, or symbols may follow an code, encoding system (wherein letters, digits, words, or symbols ''stand for'' [represent] ideas or longer names) or they may simply be arbitrary. When an identifier follows an encoding system, it is often referred to as a code or id code. For instance the ISO/IEC 11179 metadata registry standard defines a code as ''system of valid symbols that substitute for longer values'' in contrast to identifiers wi ...
