UVC-based Preservation
UVC-based preservation is an archival strategy for handling the preservation of digital objects. It employs the use of a Universal Virtual Computer (UVC)—a virtual machine (VM) specifically designed for archival purposes, that allows both emulation and migration to a language-neutral format like XML. Background to the development of a UVC approach Digital preservation problem Preservation of digital resources is of a paramount importance for deposit libraries, research libraries, archives, government agencies, and actually most organizations.Lorie R. A., 2002. A Methodology and System for Preserving Digital Data. Proceedings of the 2nd ACM/IEEE-CS joint conference on Digital libraries, Portland, Oregon, USA. 14–18 July 2002. New York, NY: Association for Computing Machinery. pp. 312-319 The dominant approach to digital preservation is migration. Migration entails making periodic transformations of archived information into new logical formats as their native formats, or the s ...

Archival Science
Archival science, or archival studies, is the study and theory of building and Curator, curating archives, which are collections of documents, Sound recording and reproduction, recordings, photographs and various other materials in physical or digital formats. To build and curate an archive, one must acquire and evaluate the materials, and be able to access them later. To this end, archival science seeks to improve methods for Archival appraisal, appraising, storing, Preservation (library and archival science), preserving, and Archival processing, processing (arranging and describing) collections of materials. An archival record preserves data that is not intended to change. In order to be of value to society, archives must be trustworthy. Therefore, an archivist has a responsibility to authenticate archival materials, such as historical documents, and to ensure their reliability, integrity, and usability. Archival records must be what they claim to be; accurately represent the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Application
Application software is any computer program that is intended for end-user use not computer operator, operating, system administration, administering or computer programming, programming the computer. An application (app, application program, software application) is any program that can be categorized as application software. Common types of applications include word processor, Media player (software), media player and accounting software. The term ''application software'' refers to all applications collectively and can be used to differentiate from system software, system and utility software, utility software. Applications may be bundled with the computer and its system software or published separately. Applications may be proprietary software, proprietary or Open-source software, open-source. The short term ''app'' (coined in 1981 or earlier) became popular with the 2008 introduction of the App Store (Apple), iOS App Store, to refer to Mobile app, applications for mobile d ...

Preservation (library And Archival Science)
In Conservation and restoration of cultural property, conservation, Library science, library and archival science, preservation is a set of preventive conservation activities aimed at prolonging the life of a record, book, or object while making as few changes as possible. Preservation activities vary widely and may include monitoring the condition of items, maintaining the temperature and humidity in collection storage areas, writing a plan in case of emergencies, digitizing items, writing relevant metadata, and increasing accessibility. Preservation, in this definition, is practiced in a library or an archive by a Conservator-restorer, conservator, librarian, archivist, or other professional when they perceive a collection or record is in need of maintenance. Preservation should be distinguished from interventive Conservation and restoration of books, manuscripts, documents and ephemera, conservation and restoration, which refers to the treatment and repair of individual items ...

Digital Obsolescence
Digital obsolescence is the risk of data loss because of inabilities to access digital assets, due to the hardware or software required for information retrieval being repeatedly replaced by newer devices and systems, resulting in increasingly incompatible formats. While the threat of an eventual " digital dark age" (where large swaths of important cultural and intellectual information stored on archaic formats becomes irretrievably lost) was initially met with little concern until the 1990s, modern digital preservation efforts in the information and archival fields have implemented protocols and strategies such as data migration and technical audits, while the salvage and emulation of antiquated hardware and software address digital obsolescence to limit the potential damage to long-term information access.

Emulator
In computing, an emulator is Computer hardware, hardware or software that enables one computer system (called the ''host'') to behave like another computer system (called the ''guest''). An emulator typically enables the host system to run software or use peripheral devices designed for the guest system. Emulation refers to the ability of a computer program in an electronic device to emulate (or imitate) another program or device. Many printer (computing), printers, for example, are designed to emulate Hewlett-Packard, HP LaserJet printers because a significant amount of software is written specifically for HP models. If a non-HP printer emulates an HP printer, any software designed for an actual HP printer will also function on the non-HP device, producing equivalent print results. Since at least the 1990s, many video game enthusiasts and hobbyists have used emulators to play classic arcade games from the 1980s using the games' original 1980s machine code and data, which is in ...

Common Language Runtime
The Common Language Runtime (CLR), the virtual machine component of Microsoft .NET Framework, manages the execution of .NET programs. Just-in-time compilation converts the managed code (compiled intermediate language code) into machine instructions which are then executed on the CPU of the computer. The CLR provides additional services including memory management, type safety, exception handling, garbage collection, security and thread management. All programs written for the .NET Framework, regardless of programming language, are executed in the CLR. All versions of the .NET Framework include CLR. The CLR team was started June 13, 1998. CLR implements the Virtual Execution System (VES) as defined in the Common Language Infrastructure (CLI) standard, initially developed by Microsoft itself. A public standard defines the Common Language Infrastructure specification. During the transition from legacy .NET technologies like the .NET Framework and its proprietary runtime t ...

Java Virtual Machine
A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation. Having a specification ensures interoperability of Java programs across different implementations so that program authors using the Java Development Kit (JDK) need not worry about idiosyncrasies of the underlying hardware platform. The JVM reference implementation is developed by the OpenJDK project as open source code and includes a JIT compiler called HotSpot. The commercially supported Java releases available from Oracle are based on the OpenJDK runtime. Eclipse OpenJ9 is another open source JVM for OpenJDK. JVM specification The Java virtual machine is an abstract (virtual) computer defined by a specification. It is a part of the Java runtime environment. The garbage collection ...
