WebDAV
WebDAV (Web Distributed Authoring and Versioning) is a set of extensions to the Hypertext Transfer Protocol (HTTP), which allows user agents to collaboratively author contents ''directly'' in an HTTP web server by providing facilities for concurrency control and namespace operations, thus allowing Web to be viewed as a ''writeable, collaborative medium'' and not just a read-only medium. WebDAV is defined in by a working group of the Internet Engineering Task Force (IETF). The WebDAV protocol provides a framework for users to create, change and move documents on a server. The most important features include the maintenance of properties about an author or modification date, namespace management, collections, and overwrite protection. Maintenance of properties includes such things as the creation, removal, and querying of file information. Namespace management deals with the ability to copy and move web pages within a server's namespace. Collections deal with the creation, re ...

ICalendar
The Internet Calendaring and Scheduling Core Object Specification (iCalendar) is a media type which allows users to store and exchange calendaring and scheduling information such as events, to-dos, journal entries, and free/busy information, and together with its associated standards has been a cornerstone of the standardization and interoperability of digital calendars across different vendors. Files formatted according to the specification usually have an extension of .ics. With supporting software, such as an email reader or calendar application, recipients of an iCalendar data file can respond to the sender easily or counter-propose another meeting date/time. The file format is specified in a proposed Internet standard (RFC 5545) for calendar data exchange. iCalendar is used and supported by many products, including Google Calendar, Apple Calendar (formerly iCal), HCL Domino (formerly IBM Notes and Lotus Notes), Yahoo! Calendar, GNOME Evolution, eM Client, Lightning ...

Within the market of desktop and laptop computers it is the second most widely used desktop OS, after Microsoft Windows and ahead of ChromeOS. macOS succeeded the classic Mac OS, a Mac operating system with nine releases from 1984 to 1999.

Horde (software)
Horde is a free web-based groupware. The components of this groupware rest on the Horde framework. This PHP-based framework provides all the elements required for rapid web application development. Horde offers applications such as the Horde IMP email client, a groupware package (calendar, notes, tasks, file manager), a wiki and a time and task tracking software. History The Horde framework evolved from the IMP (Internet Messaging Project) webmail that Chuck Hagenbuch published on Freshmeat in 1998. A constant stream of feature requests not all fitting for a webmail application led to the development of a more generic web application backbone: the Horde framework. The first announcement on Freshmeat was version 1.3.3 at the beginning of 2001. The release of Horde 2.0 and IMP 3.0 was the first one with two truly separate components. Horde as a generic web application framework primarily supported the webmail as well as a set of groupware applications by the time Horde 3 ...
