Overview
Chandler is a discontinued personal information management software suite described by its developers as a "Note-to-Self Organizer" designed for personal and small-group task management and calendaring. It is free software, previously released under the GNU General Public License, and now released under the Apache License 2.0. It is inspired by a PIM from the 1980s called Lotus Agenda, notable because of its "free-form" approach to information management. Lead developer of Agenda, Mitch Kapor, was also involved in the vision and management of Chandler.
Chandler consists of a cross-platform desktop application (Windows, Mac OS X, Linux), the Chandler Hub Sharing Service, Chandler Server, Chandler Quick Entry for iPhone, and Chandler Quick Entry for Android. Version 1.0 of the software was released on August 8, 2008.
Chandler was developed by the Open Source Applications Foundation (OSAF). It is named after the mystery novelist Raymond Chandler.
Chandler design goals
Chandler aimed to create a workflow for personal information management different from that in other PIMs. Its approach is mainly based in creating a unified representation for the storage of tasks and information so that they can be classified in a homogeneous way, refining that information through an iterative workflow, and allowing easy collaboration on the defined items. Other goals included:
Build on open source software that supports open standards, choosing projects that are reliable, well documented, and widely used
Use the Python language at the top level to orchestrate low level, higher performance code
Design a platform that supports an extensible modular architecture
For the desktop client, choose a cross-platform user interface toolkit that provides native user experience
Use a persistent object database
Build in security from the ground up
Build an architecture that supports sharing, communication, and collaboration
