DocBook
DocBook is a Semantics (computer science), semantic markup language for technical documentation. It was originally intended for writing technical documents related to computer hardware and software, but it can be used for any other sort of documentation. As a semantic language, DocBook enables its users to create separation of presentation and content, document content in a presentation-neutral form that captures the logical structure of the content; that content can then be published in a variety of formats, including HTML, XHTML, EPUB, Portable Document Format, PDF, Manual page (Unix), man pages, WebHelp and Microsoft Compiled HTML Help, HTML Help, without requiring users to make any changes to the source. In other words, when a document is written in DocBook format it becomes easily portable into other formats, rather than needing to be rewritten. Design DocBook is an XML language. In its current version (5.x), DocBook's language is formally defined by a RELAX NG XML schema, ...

SGML
The Standard Generalized Markup Language (SGML; International Organization for Standardization, 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 International Organization for Standardization, 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 accept ...

Markup Language
A markup language is a Encoding, text-encoding system which specifies the structure and formatting of a document and potentially the relationships among its parts. Markup can control the display of a document or enrich its content to facilitate automated processing. A markup language is a set of rules governing what markup information may be included in a document and how it is combined with the content of the document in a way to facilitate use by humans and computer programs. The idea and terminology evolved from the "marking up" of paper manuscripts (e.g., with revision instructions by editors), traditionally written with a red pen or blue pencil (editing), blue pencil on authors' manuscripts. Older markup languages, which typically focus on typography and presentation, include Troff, TeX, and LaTeX. Scribe (markup language), Scribe and most modern markup languages, such as Extensible Markup Language, XML, identify document components (for example headings, paragraphs, and tabl ...

OASIS (organization)
The Organization for the Advancement of Structured Information Standards (OASIS; ) is an Trade association, industry consortium that develops Technical standard, technical standards for information technology. History OASIS was founded under the name "SGML Open" in 1993. It began as a trade association of Standard Generalized Markup Language (SGML) tool vendors to cooperatively promote the adoption of SGML through mainly educational activities, though some amount of technical activity was also pursued including an update of the CALS Table Model specification and specifications for fragment interchange and entity management. In 1998, with the movement of the industry to XML, SGML Open changed its emphasis from SGML to XML, and changed its name to OASIS Open to be inclusive of XML and reflect an expanded scope of technical work and standards. The focus of the consortium's activities also moved from promoting adoption (as XML was getting much attention on its own) to developing ...

Manual Page (Unix)
A man page (short for manual page) is a form of software documentation found on Unix and Unix-like operating systems. Topics covered include programs, system libraries, system calls, and sometimes local system details. The local host administrators can create and install manual pages associated with the specific host. A manual end user may invoke a documentation page by issuing the man command followed by the name of the item for which they want the documentation. These manual pages are typically requested by end users, programmers and administrators doing real time work but can also be formatted for printing. By default, man typically uses a formatting program such as nroff with a macro package or mandoc, and also a terminal pager program such as more or less to display its output on the user's screen. Man pages are often referred to as an ''online'' form of software documentation, even though the man command does not require internet access. The environment variable MAN ...

XML Editor
An XML editor is a markup language editor with added functionality to facilitate the editing of XML. This can be done using a plain text editor, with all the code visible, but XML editors have added facilities like tag completion and menus and buttons for tasks that are common in XML editing, based on data supplied with document type definition (DTD) or the XML tree. There are also graphical XML editors that hide the code in the background and present the content to the user in a more user-friendly format, approximating the rendered version or editing forms. This is helpful for situations where people who are not fluent in XML code need to enter information in XML based documents such as time sheets and expenditure reports. And even if the user is familiar with XML, use of such editors, which take care of syntax details, is often faster and more convenient. Functionality beyond syntax highlighting An XML editor goes beyond the syntax highlighting offered by many plaintext edi ...

RELAX NG
In computing, RELAX NG (REgular LAnguage for XML Next Generation) is a schema language for XML—a RELAX NG schema specifies a pattern for the structure and content of an XML document. A RELAX NG schema is itself an XML document but RELAX NG also offers a popular compact, non-XML syntax. Compared to other XML schema languages RELAX NG is considered relatively simple. It was defined by a committee specification of the OASIS RELAX NG technical committee in 2001 and 2002, based on Murata Makoto's RELAX and James Clark's TREX, and also by part two of the international standard ISO/ IEC 19757: Document Schema Definition Languages ( DSDL). ISO/IEC 19757-2 was developed by ISO/IEC JTC 1/SC 34 and published in its first version in 2003. Comparison with W3C XML Schema Although the RELAX NG specification was developed at roughly the same time as the W3C XML Schema specification, the latter was arguably better known and more widely implemented in both open-source and proprietary XML ...

Portable Document Format
Portable document format (PDF), standardized as ISO 32000, is a file format developed by Adobe in 1992 to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images and other information needed to display it. PDF has its roots in "The Camelot Project" initiated by Adobe co-founder John Warnock in 1991. PDF was standardized as ISO 32000 in 2008. The last edition as ISO 32000-2:2020 was published in December 2020. PDF files may contain a variety of content besides flat text and graphics including logical structuring elements, interactive elements such as annotations and form-fields, layers, rich media (including video content), three-dimensional objects using U3D or PRC, and various other data formats. The PDF specific ...

HAL Computer Systems
HAL Computer Systems, Inc was a Campbell, California-based computer manufacturer founded in 1990 by Andrew Heller, a principal designer of the original IBM POWER architecture. His idea was to build computers based on a RISC architecture for the commercial market. The inspiration of the name comes from the Arthur C. Clarke novel '' 2001: A Space Odyssey''. The company's intent to develop a high-performance microprocessor implementing the SPARC architecture prompted Fujitsu to fund the company in 1991. $40.2 million was invested in return for a 44% stake. As part of the deal: # Fujitsu agreed to not increase their ownership of HAL. # Fujitsu would fabricate HAL's microprocessor designs. # Fujitsu would make its patents available to HAL. # Fujitsu would manufacture some of the HAL machines, and market them in Asia. In return, HAL gave Fujitsu access to the technology it was developing. By this time, HAL had 140 employees. In mid-1993, Heller resigned from his position as chair ...

Writing System
A writing system comprises a set of symbols, called a ''script'', as well as the rules by which the script represents a particular language. The earliest writing appeared during the late 4th millennium BC. Throughout history, each independently invented writing system gradually emerged from a system of proto-writing, where a small number of ideographs were used in a manner incapable of fully encoding language, and thus lacking the ability to express a broad range of ideas. Writing systems are generally classified according to how its symbols, called ''graphemes'', relate to units of language. Phonetic writing systemswhich include alphabets and syllabariesuse graphemes that correspond to sounds in the corresponding spoken language. Alphabets use graphemes called ''letter (alphabet), letters'' that generally correspond to spoken phonemes. They are typically divided into three sub-types: ''Pure alphabets'' use letters to represent both consonant and vowel sounds, ''abjads'' gene ...

FreeBSD
FreeBSD is a free-software Unix-like operating system descended from the Berkeley Software Distribution (BSD). The first version was released in 1993 developed from 386BSD, one of the first fully functional and free Unix clones on affordable home-class hardware, and has since continuously been the most commonly used BSD-derived operating system. FreeBSD maintains a complete system, delivering a kernel, device drivers, userland utilities, and documentation, as opposed to Linux only delivering a kernel and drivers, and relying on third-parties such as GNU for system software. The FreeBSD source code is generally released under a permissive BSD license, as opposed to the copyleft GPL used by Linux. The project includes a security team overseeing all software shipped in the base distribution. Third-party applications may be installed using the pkg package management system or from source via FreeBSD Ports. The project is supported and promoted by the FreeBSD Foundation ...

Usenet
Usenet (), a portmanteau of User's Network, is a worldwide distributed discussion system available on computers. It was developed from the general-purpose UUCP, Unix-to-Unix Copy (UUCP) dial-up network architecture. Tom Truscott and Jim Ellis (computing), Jim Ellis conceived the idea in 1979, and it was established in 1980.''From Usenet to CoWebs: interacting with social information spaces'', Christopher Lueg, Danyel Fisher, Springer (2003), , Users read and post messages (called ''articles'' or ''posts'', and collectively termed ''news'') to one or more topic categories, known as Usenet newsgroup, newsgroups. Usenet resembles a bulletin board system (BBS) in many respects and is the precursor to the Internet forums that have become widely used. Discussions are Threaded discussion, threaded, as with web forums and BBSes, though posts are stored on the server sequentially.
