Open Source Productivity Software Guide
Open source productivity software is an increasingly popular type of program that allows users to create and share documents, spreadsheets, presentations, graphics, and other types of content. Open source software is released in a public forum with a free license, allowing anyone to use it for any purpose without requiring payment or registration. This means that the user can modify the code as needed and even redistribute the program provided they include the same license terms.
The most common type of open source productivity software includes office suites such as LibreOffice, OpenOffice, Apache OpenOffice (which are considered forks of Oracle’s original Java-based Openoffice), and Calligra – all of which provide word processing, spreadsheet and presentation programs.
