Document Content Architecture
Document Content Architecture, or DCA for short, is a standard developed by IBM for text documents in the early 1980s. DCA was used on mainframe and IBM i systems, and formed the basis of DisplayWrite's file format. DCA was later extended as MO:DCA (Mixed Object Document Content Architecture), which added embedded data files. The original purpose of DCA was to provide a common document format that could be used across multiple IBM word processing platforms, such as the IBM PC, IBM mainframes, the Displaywriter System, and the IBM 5520 Administrative System. DCA defines two types of documents: * ''Revisable-Form Text'' (DCA/RFT) which is editable. * ''Final-Form Text'' (DCA/FFT) which is "formatted for a particular output device and cannot be changed." Description DCA defines a data stream representing a document. MO:DCA is the wrapper or container for various ''objects'' that can make up the document. Each object is defined by its own subordinate architecture. The architec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Document File Format
A document file format is a text or binary file format for storing documents on a storage media, especially for use by computers. There currently exist a multitude of incompatible document file formats. Examples of XML-based open standards are DocBook, XHTML, and, more recently, the ISO/IEC standards OpenDocument (ISO 26300:2006) and Office Open XML (ISO 29500:2008). In 1993, the ITU-T tried to establish a standard for document file formats, known as the Open Document Architecture (ODA) which was supposed to replace all competing document file formats. It is described in ITU-T documents T.411 through T.421, which are equivalent to ISO 8613. It did not succeed. Page description languages such as PostScript and PDF have become the ''de facto'' standard for documents that a typical user should only be able to create and read, not edit. In 2001, a series of ISO/IEC standards for PDF began to be published, including the specification for PDF itself, ISO-32000. HTML is the most used ...

Bar Code
A barcode or bar code is a method of representing data in a visual, Machine-readable data, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which there are several types. Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons and other patterns, called ''matrix codes'' or ''2D barcodes'', although they do not use bars as such. 2D barcodes can be read using purpose-built 2D optical scanners, which exist in a few different forms. 2D barcodes can also be read by a digital camera connected to a microcomputer running software that takes a photographic image of the barcode and analyzes the image to deconstruct and decode the 2D barcode. A mobile device with an inbuilt camera, such as smartphone, can function as the latter type of 2D barcode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rich Text Format
) As an example, the following RTF code would be rendered as follows: This is some bold text. Character encoding A standard RTF file can only consist of 7-bit ASCII characters, but can use escape sequences to encode other characters. The two character escapes are code page escapes and, starting with RTF 1.5, Unicode escapes. In a code page escape, two hexadecimal digits following a backslash and typewriter apostrophe denote a character taken from a Windows code page. For example, if the code page is set to Windows-1256, the sequence \'c8 will encode the Arabic letter ''bāʼ'' ب. It is also possible to specify a "Character Set" in the preamble of the RTF document and associate it to a header. For example, the preamble has the text \f3\fnil\fcharset128, then, in the body of the document, the text \f3\'bd\'f0 will represent the code point 0xbd 0xf0 from the Character Set 128 (which corresponds to the Shift-JIS code page), which encodes "金". For a Unicode escape, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTML
The HyperText Markup Language or HTML is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript. Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for the appearance of the document. HTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes, and other items. HTML elements are delineated by ''tags'', written using angle brackets. Tags such as and directly introduce content into the page. Other tags such as surround ...

SGML
The Standard Generalized Markup Language (SGML; ISO 8879:1986) is a standard for defining generalized markup languages for documents. ISO 8879 Annex A.1 states that generalized markup is "based on two postulates": * Declarative: Markup should describe a document's structure and other attributes rather than specify the processing that needs to be performed, because it is less likely to conflict with future developments. * Rigorous: In order to allow markup to take advantage of the techniques available for processing, markup should rigorously define objects like programs and databases. DocBook SGML and LinuxDoc are examples which used SGML tools. Standard versions SGML is an ISO standard: "ISO 8879:1986 Information processing – Text and office systems – Standard Generalized Markup Language (SGML)", of which there are three versions: * Original ''SGML'', which was accepted in October 1986, followed by a minor Technical Corrigendum. * ''SGML (ENR)'', in 1996, resul ...

IBM OfficeVision
OfficeVision was an IBM proprietary office support application. History PROFS, DISOSS and Office/36 OfficeVision started as a product for the VM operating system named PROFS (for PRofessional OFfice System) and was initially made available in 1981. Before that it was just a PRPQ (Programming Request for Price Quotation), an IBM administrative term for non-standard software offerings with unique features, support and pricing. The first release of PROFS was developed by IBM in Poughkeepsie, NY, in conjunction with Amoco, from a prototype developed years earlier by Paul Gardner and others. Subsequent development took place in Dallas. The editor XEDIT was the basis of the word processing function in PROFS. PROFS itself had descended from OFS (Office System) developed also on the same laboratory and first installed in October 1974. This was a primitive solution for office automation created between 1970 and 1972, which was replacement for an in-house system. Compared to Pough ...

Mainframe Computers
A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, servers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers. The term ''mainframe'' was derived from the large cabinet, called a ''main frame'', that housed the central processing unit and main memory of early computers. Later, the term ''mainframe'' was used to distinguish high-end commercial computers from less powerful machines. Design Modern mainframe design is characterized less b ...

System/360
The IBM System/360 (S/360) is a family of mainframe computer systems that was announced by IBM on April 7, 1964, and delivered between 1965 and 1978. It was the first family of computers designed to cover both commercial and scientific applications and to cover a complete range of applications from small to large. The design distinguished between architecture and implementation, allowing IBM to release a suite of compatible designs at different prices. All but the only partially compatible Model 44 and the most expensive systems use microcode to implement the instruction set, which features 8-bit byte addressing and binary, decimal, and hexadecimal floating-point calculations. The System/360 family introduced IBM's Solid Logic Technology (SLT), which packed more transistors onto a circuit card, allowing more powerful but smaller computers to be built. The slowest System/360 model announced in 1964, the IBM System/360 Model 30, Model 30, could perform up to 34,500 instructions ...

Word Processor
A word processor (WP) is a device or computer program that provides for input, editing, formatting, and output of text, often with some additional features. Word processor (electronic device), Early word processors were stand-alone devices dedicated to the function, but current word processors are word processor programs running on general purpose computers. The functions of a word processor program fall somewhere between those of a simple text editor and a fully functioned desktop publishing program. However, the distinctions between these three have changed over time and were unclear after 2010. Background Word processors did not develop ''out'' of computer technology. Rather, they evolved from mechanical machines and only later did they merge with the computer field. The history of word processing is the story of the gradual automation of the physical aspects of writing and editing, and then to the refinement of the technology to make it available to corporations and Indi ...

IBM DisplayWrite
DisplayWrite (sometimes written as Displaywrite) was a word processor software application that IBM developed and marketed for the IBM PC and PCjr. It was among the company's first internally developed, commercially sold PC software titles. DisplayWrite's feature set was based on the IBM Displaywriter System, a dedicated microcomputer-based word processing machine. Because the two systems were so similar, an experienced Displaywriter user could start using DisplayWrite immediately. Versions DisplayWrite/PC For the Intel platform there were DisplayWrite versions for PC/MS-DOS and DisplayWrite 5/2 programmed under OS/2. DisplayWrite/36 DisplayWrite/36 was the word processing component of IBM Office/36, which allowed an office to use the SQL-based database file for labels and form letters. DisplayWrite/370 DisplayWrite/370, a much more powerful version with full graphics and WYSIWYG support, was supported for IBM zSeries mainframe computers until May 2015. (see IBM Dis ...

Advanced Function Presentation
Advanced Function Presentation (AFP) is a presentation architecture and family of associated printer software and hardware that provides for document and information presentation independent of specific applications and devices. Using AFP, users can control formatting, the form of paper output, whether a document is to be printed or viewed online, and manage document storage and access in a distributed network across multiple operating system platforms. AFP is primarily used in large enterprises for production variable data printing (VDP). AFP applications allow users or print room operators to distribute print jobs among a group of printers and to designate backup printers when one fails. AFP is considered to be a "cornerstone" of electronic document management (EDM) applications such as print-and-view, archive and retrieval, and enterprise report management (ERM). History AFP was originally developed by IBM as a general purpose document and information presentation architectu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
