Computer Program
A computer program is a sequence or set of instructions in a programming language for a computer to execute. Computer programs are one component of software, which also includes documentation and other intangible components. A computer program in its human-readable form is called source code. Source code needs another computer program to execute because computers can only execute their native machine instructions. Therefore, source code may be translated to machine instructions using the language's compiler. (Assembly language programs are translated using an assembler.) The resulting file is called an executable. Alternatively, source code may execute within the language's interpreter. If the executable is requested for execution, then the operating system loads it into memory and starts a process. The central processing unit will soon switch to this process so it can fetch, decode, and then execute each machine instruction. If the source code is requested for executio ...

Stanca Act
The Stanca Act is an Italian law of 2004 that promotes accessibility of information technology. The law also applies to Italian government websites. History The name of this law refers to its proponent, Lucio Stanca, Minister of Innovations during the second cabinet of Berlusconi. The law was unanimously approved by Parliament, was published in the Italian Gazzetta Ufficiale of 17 January 2004, and became operational after more than a year. On 16 September 2013 an update of this law was published in the Gazzetta Ufficiale. The update aligns the law with W3C WCAG 2.0 standards. External links * ThStanca Act(English Version).

Pisa
Pisa ( , or ) is a city and ''comune'' in Tuscany, central Italy, straddling the Arno just before it empties into the Ligurian Sea. It is the capital city of the Province of Pisa. Although Pisa is known worldwide for its leaning tower, the city contains more than twenty other historic churches, several medieval palaces, and bridges across the Arno. Much of the city's architecture was financed from its history as one of the Italian maritime republics. The city is also home to the University of Pisa, which has a history going back to the 12th century, the Scuola Normale Superiore di Pisa, founded by Napoleon in 1810, and its offshoot, the Sant'Anna School of Advanced Studies.Scuola Superiore Sant'Anna di Pisa Information statistics History |
National Research Council Of Italy
The National Research Council (Italian: ''Consiglio Nazionale delle Ricerche, CNR'') is the largest research council in Italy. As a public organisation, its remit is to support scientific and technological research. Its headquarters are in Rome. History The institution was founded in 1923. The first president was Vito Volterra, succeeded by Guglielmo Marconi. The process of improvement of the national scientific research, through the use of specific laws, (see Law 59/1997), affects many research organisations, and amongst them is CNR, whose "primary function is to carry on, through its own organs, advanced basic and applied research, both to develop and maintain its own scientific competitiveness, and to be ready to take part effectively in a timely manner in the strategic fields defined by the national planning system". On 23 December 1987, CNR registered the first Italian internet domain: cnr.it Reorganisation With the issuing of the legislative decree of 30 January 1999, n. ...

XML Validation
XML validation is the process of checking a document written in XML (eXtensible Markup Language) to confirm that it is both well-formed and also "valid" in that it follows a defined structure. A well-formed document follows the basic syntactic rules of XML, which are the same for all XML documents. A valid document also respects the rules dictated by a particular DTD or XML schema. Automated tools – validators – can perform well-formedness tests and many other validation tests, but not those that require human judgement, such as correct application of a schema to a data set. Standards * OASIS CAM is a standard specification that provides contextual validation of content and structure that is more flexible than basic schema validations. * Schematron, a method for advanced XML validation. Tools * '' xmllint'' is a command line XML tool that can perform XML validation. It can be found in UNIX / Linux Linux ( or ) is a family of open-source Unix-like operating ...

Well-formed Element
In web page design, and generally for all markup languages such as SGML, HTML, and XML, a well-formed element is one that is either a) opened and subsequently closed, or b) an empty element, which in that case must be terminated; and in either case which is properly nested so that it does not overlap with other elements. For example, in HTML: word is a well-formed element, while is not, since the bold element is not closed. In XHTML, and XML, empty elements (elements that inherently have no content) are terminated by putting a slash at the end of the "opening" (only) tag, e.g. etc. In HTML 4.01 and earlier, no slash is added to terminate the element. HTML5 does not require one, but it is often added for compatibility with XHTML and XML processing. In a well-formed document, * all elements are well-formed, and * a single element, known as the root element, contains all of the other elements in the document. For example, the code below is not well-formed HTML, because t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
W3C Markup Validation Service
The Markup Validation Service is a validator by the World Wide Web Consortium (W3C) that allows Internet users to check pre-HTML5 HTML and XHTML documents for well-formed markup against a document type definition. Markup validation is an important step towards ensuring the technical quality of web pages. However, it is not a complete measure of web standards conformance. Though W3C validation is important for browser compatibility and site usability, it has not been confirmed what effect it has on search engine optimization. As HTML5 has removed the use of DTD in favor of a "Living Standard", the traditional Markup Validation Service is not applicable to these formats. Validation is instead performed using an open-source "Nu Validator", an instance of which is provided by W3C. History The Markup Validation Service began as ''The Kinder, Gentler HTML Validator'', a project by Gerald Oskoboiny. It was developed to be a more intuitive version of the first online HTML validator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTML Tidy
HTML Tidy is a console application for correcting invalid HyperText Markup Language (HTML), detecting potential web accessibility errors, and for improving the layout and indent style of the resulting markup. It is also a cross-platform library for computer applications that provides HTML Tidy's features. History HTML Tidy was developed by Dave Raggett of the World Wide Web Consortium (W3C). Later it was released as a SourceForge project in 2003 and managed by various maintainers. In 2012, the project was moved to GitHub, and maintained by Michael Smith, also of W3C, where HTML5 support was added. In 2015, the HTML Tidy Advocacy Community Group (HTACG) was formed for management and development of HTML Tidy as a W3C Community Group. HTML Tidy source code is written in ANSI C for portability. Compiled binary files are available for a variety of platforms. It is available under the W3C Software Notice and License, a permissive BSD-style license. Up-to-date versions are availab ...

Section 508
In 1998 the US Congress amended the Rehabilitation Act to require Federal agencies to make their electronic and information technology accessible to people with disabilities. Section 508 was enacted to eliminate barriers in information technology, to make available new opportunities for people with disabilities, and to encourage development of technologies that will help achieve these goals. The law applies to all Federal agencies when they develop, procure, maintain, or use electronic and information technology. Under Section 508 (), agencies must give employees with disabilities and members of the public access to information that is comparable to the access available to others. History Section 508 was originally added as an amendment to the ''Rehabilitation Act of 1973'' in 1986. The original section 508 dealt with electronic and information technologies, in recognition of the growth of this field. In 1997, The Federal Electronic and Information Technology Accessibility and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Validity (logic)
In logic, specifically in deductive reasoning, an argument is valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. It is not required for a valid argument to have premises that are actually true, but to have premises that, if they were true, would guarantee the truth of the argument's conclusion. Valid arguments must be clearly expressed by means of sentences called well-formed formulas (also called ''wffs'' or simply ''formulas''). The validity of an argument can be tested, proved or disproved, and depends on its logical form. Arguments In logic, an argument is a set of statements expressing the ''premises'' (whatever consists of empirical evidences and axiomatic truths) and an ''evidence-based conclusion.'' An argument is ''valid'' if and only if it would be contradictory for the conclusion to be false if all of the premises are true. Validity doesn't require the truth of the premises, ins ...

WCAG
The Web Content Accessibility Guidelines (WCAG) are part of a series of web accessibility guidelines published by the Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C), the main international standards organization for the Internet. They are a set of recommendations for making Web content more accessible, primarily for people with disabilities—but also for all user agents, including highly limited devices, such as mobile phones. WCAG 2.0, were published in December 2008 and became an ISO standard, ISO/IEC 40500:2012 in October 2012. WCAG 2.1 became a W3C Recommendation in June 2018. __TOC__ History Earlier guidelines (1995–1998) The first web accessibility guideline was compiled by Gregg Vanderheiden and released in January 1995, just after the 1994 Second International Conference on the World-Wide Web (WWW II) in Chicago (where Tim Berners-Lee first mentioned disability access in a keynote speech after seeing a pre-conference workshop on acces ...
