Org is a mode for keeping notes, maintaining TODO lists, and doing project planning with a fast and effective plain-text system.
Org develops organizational tasks around NOTES files that contain lists or information about projects as plain text. Org is implemented on top of Outline mode, which makes it possible to keep the content of large files well structured. Visibility cycling and structure editing help to work with the tree. Tables are easily created with a built-in table editor. Org supports TODO items, deadlines, time stamps, and scheduling. It dynamically compiles entries into an agenda that utilizes and smoothly integrates much of the Emacs calendar and diary. Plain text URL-like links connect to websites, emails, Usenet messages, BBDB entries, and any files related to the projects. For printing and sharing of notes, an Org file can be exported as a structured ASCII file, as HTML, or (TODO and agenda items only) as an iCalendar file. It can also serve as a publishing tool for a set of linked web pages.
An important design aspect that distinguishes Org from for example Planner/Muse is that it encourages to store every piece of information only once. In Planner, you have project pages, day pages and possibly other files, duplicating some information such as tasks. In Org, you only have notes files. In your notes you mark entries as tasks, label them with tags and timestamps. All necessary lists like a schedule for the day, the agenda for a meeting, tasks lists selected by tags etc are created dynamically when you need them.
Org keeps simple things simple. When first fired up, it should feel like a straightforward, easy to use outliner. Complexity is not imposed, but a large amount of functionality is available when you need it. Org is a toolbox and can be used in different ways, for example as:
• outline extension with visibility cycling and structure editing • ASCII system and table editor for taking structured notes • ASCII table editor with spreadsheet-like capabilities • TODO list editor • full agenda and planner with deadlines and work scheduling • environment to implement David Allen's GTD system • a basic database application • simple hypertext system, with HTML and LaTeX export • publishing tool to create a set of interlinked webpages
Org's automatic, context sensitive table editor with spreadsheet capabilities can be integrated into any major mode by activating the minor Orgtbl mode. Using a translation step, it can be used to maintain tables in arbitrary file types, for example in LaTeX. The structure editing and list creation capabilities can be used outside Org with the minor Orgstruct mode.
