OpenFormula
OpenFormula is an open standard for exchanging recalculated formulae in spreadsheets. OpenFormula is included in version 1.2 of the OpenDocument standard. OpenFormula was initially proposed and drafted by David A. Wheeler. History Discussion of need OpenDocument 1.0 is a specification for the exchange of office documents, and is capable of describing mathematical formulas that are displayed on the screen (through its reuse of the MathML standard). It's also capable of exchanging spreadsheet data, formats, pivot tables, and other information typically included in a spreadsheet. OpenDocument can exchange spreadsheet formulae (formulae that are recalculated in the spreadsheet); formulae are exchanged as values of the attribute table: formula. Open Formula resulted from the belief by some users that the syntax and semantics of table formulas were not defined in sufficient detail. Version 1.0 of the specification defined spreadsheet formulae using a set of simple examples which sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenDocument
The Open Document Format for Office Applications (ODF), also known as OpenDocument, standardized as ISO 26300, is an open file format for word processor, word processing documents, spreadsheets, Presentation program, presentations and graphics and using Zip (file format), ZIP-compressed XML files. It was developed with the aim of providing an open, XML-based file format specification for office applications.

It was based on the Sun Microsystems specification for OpenOffice.org XML, the default format for OpenOffice.org and LibreOffice. It was originally developed for StarOffice "to provide an open standard for office documents." In addition to being an OASIS standard, it is published as an International Organization for Standardization, ISO/International Electrotechnical Commission, IEC i ...

Astrophysics
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. As one of the founders of the discipline, James Keeler, said, astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space—''what'' they are, rather than ''where'' they are", which is studied in celestial mechanics. Among the subjects studied are the Sun ( solar physics), other stars, galaxies, extrasolar planets, the interstellar medium, and the cosmic microwave background. Emissions from these objects are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, ''astrophysicists'' apply concepts and methods from many disciplines of physics, including classical mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum ...

Lotus 1-2-3
Lotus 1-2-3 is a discontinued spreadsheet program from Lotus Software (later part of IBM). It was the first killer application of the IBM PC, was hugely popular in the 1980s, and significantly contributed to the success of IBM PC-compatibles in the business market. The first spreadsheet, VisiCalc, had helped launch the Apple II as one of the earliest personal computers in business use. With IBM's entry into the market, VisiCalc was slow to respond, and when they did, they launched what was essentially a straight port of their existing system despite the greatly expanded hardware capabilities. Lotus's solution was marketed as a three-in-one integrated solution: it handled spreadsheet calculations, database functionality, and graphical charts, hence the name "1-2-3", though how much database capability the product actually had was debatable, given the sparse memory left over after launching 1-2-3. It quickly overtook VisiCalc, as well as Multiplan and SuperCalc, the two Visi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

KOffice
KOffice was a free and open source office and graphics suite developed by KDE for Unix-like and Windows systems. KOffice contains a word processor ( KWord), a spreadsheet ( KSpread), a presentation program ( KPresenter), and a number of other components that varied over the course of its development. KOffice was superseded by Calligra Suite in KDE. The KDE3 version is maintained by the Trinity Desktop project. After development began in 1997, two major stable releases of KOffice were published: Version 1.0 in 2000 and 2.0 in 2009. Following internal conflicts, the majority of KOffice developers split off in 2010 – resulting in the creation of Calligra Suite. Two years later, in September 2012, the KOffice.org website went offline. It now redirects to Calligra.org. History First generation Initial work on KOffice development began in 1997, by Reginald Stadlbauer with KPresenter, followed by KWord in 1998.
