The OSAF's Chandler PIM

Last week, the Open Source Applications Foundation (OSAF) released version 0.1 of Chandler, an open-source Personal Information Management (PIM) system. The [OSAF] Product Roadmap shows the long-term release plan. As Chandler matures, it will be aimed at increasingly larger audiences. The release levels are aimed at five classes of users: developers, early adopters, higher ed users, mainstream users, and conservatives. The first release opens the project up for general consumption by developers:

While we are still very early in the design and implementation process, we intend for this 0.1 release to make us a more fully open project. We have made the release available for download, opened up our bug tracking database, and opened our source code repository.

Chandler is written in the Python language and uses the wxPython GUI toolkit. The Chandler Application Architecture Overview gives a pictorial view of the various components that make up of the application.

The Chandler Current Vision document describes the aim of the project.

Chandler is intended to be an open source personal information manager for email, calendars, contacts, tasks, and general information management, as well as a platform for developing information management applications. It is currently under development and will run on Windows, Mac, and Linux-based PC's.

Chandler differs from conventional PIM solutions in the following way:

With Chandler, users will be able to organize diverse kinds of information for their own convenience -- not the computer's convenience. Chandler will have a rich ability not only to associate and interconnect items, but also to gather and collect related items in a single place creating a context sensitive "view" of many types of data, mixing-and-matching email, mailing lists, instant messages, appointments, contacts, tasks, free-form notes, blogs, web pages, documents, spreadsheets, slide shows, bookmarks, photos, MP3's, and so on (and on). Data in Chandler is stored on repositories on the user's local machine, on others' machines, and on shared resources such as servers.

This is a very different approach from that of today's common PIMs. For example, users can usually only view a given email message in one specific folder, grouped only with other email messages. In the user-centric world of Chandler, the basis of the ‘relatedness’ of items is completely at the users discretion and is merely facilitated, rather than imposed by the software.
