  • Chandler succeeds at meeting the needs of users who are tracking ‘knowledge work’
  • Chandler is not oriented around calendaring per se or around a complicated task and project landscape with many dependencies
  • we want Chandler to be more viral. We want Chandler to be easy to explain to others. We want Chandler to be found in contexts where people are already spending time. We want Chandler to be
  • ...17 more annotations...
  • even more useful as that user pulls in other people to collaborate
  • We want happy users be successful evangelists for Chandler
  • web widgets that might be deployed in different contexts — iGoogle, Facebook, on an iPhone, etc.
  • widgets should be compelling to a new user who does not use the desktop, in addition to providing features that complement the desktop. Eventually, the widgets can be building blocks
  • misperception in the press
  • Being a CalDAV reference implementation is not a priority.
  • the Microsoft product with the most overlap with our design objectives is probably OneNote
  • web widgets (in the browser, on mobile devices and on the desktop)
  • not trying to be a GTD specific tool
  • Chandler’s philosophy is different enough from GTD that it would be misleading to call Chandler a GTD tool
  • Our best articulation of our core value to date is: Chandler is a way to manage and collaborate on ideas using: A List View built around the idea of the Triage Workflow A Calendar View Chandler Hub Sharing Service
  • the user problem we are serving is an emerging market
  • there isn’t a shared, public vocabulary to describe what we’re doing
  • Better product messaging so that people understand what ‘user problem’ we’re trying to solve and how we’re trying to solve it.
  • more ways to get data in and out
  • we will not be implementing CalDAV scheduling

      CalDAV scheduling is just one aspect of CalDAV; see http://caldav.calconnect.org/standards.html
  • We’re not looking to be a cheaper alternative to Outlook/Exchange. This means we’re not investing in support for free/busy-style scheduling. We’re not looking to be the ‘everyman’s’ version of Microsoft Project or Bug and Ticket-Tracking systems. This means we’re not investing in support for complex task and project management, e.g. task dependencies, tracking percent done, time estimates, robust support for assigning tasks, etc. We’re also not going to be implementing the GTD methodology.

Gnome Evolution bug 359755 - Support for CalDAV collections - 0 views

  • GNOME Bugzilla
  • Bug 359755
  • Support for CalDAV collections
  • ...42 more annotations...
  • Product: Evolution
  • FIXED
  • enhancement
  • The definition of 'calendar-home-set' is that it returns the URL of the collection which contains the user's calendars. Not the URLs of the calendars themselves.
  • then do a Depth: 1 PROPFIND on that URL to retrieve the actual calendars
  • you will request the resourcetype & supported-calendar-component-set
  • know which ones are calendars
  • whether they support VEVENT/VTASK/VJOURNAL
  • public calendars
  • calendars for a given user offered by other users
  • the dust isn't fully settled on parts of this
  • a few tricks
  • Trick #1
  • PROPFIND request for current-user-principal
  • Also planned
  • query a 'well known URL'
  • find the right port
  • PROPFIND the /.well-known/caldav/ URL
  • Once you've *got* the principal-URL
  • PROPFIND for the group-membership
  • possibly do this repeatedly
  • Once *that's* fully expanded to a list of principal-URLs
  • query the calendar-home-set for them
  • Depth: 1 PROPFIND on those to find their calendars
  • possible simplification
  • combine two steps
  • expand-property report is defined in RFC 3253 (WebDAV Versioning)
  • DAV::expand-property REPORT
  • can't think of a way to get the actual collections
  • maybe there is some trick
  • I guess at this point
  • current-user-principal in the first instance
  • PROPFIND Depth: 1 on the calendar-home-set
  • gets you the user's direct calendars
  • differentiating
  • my approach would be
  • on demand
  • e.g. 'display delegated calendar'
  • principal-URL for the currently authenticated user
  • recursively PROPFIND
  • expand their group-membership into a tree
  • In DAViCal the public.php is specifically for looking at calendars which have been declared to need no authentication

Chandler FLOSS CalDAV

shared by Graham Perrin on 22 Dec 08 - Cached
  • Graham Perrin on 22 Dec 08
     
    A most remarkable omission from the reviews on Amazon (and presumably, from the book) is: discussion of standards, such as those relating to CalDAV. OSAF/Chandler Project members made significant contributions to the drafting and setting of standards. Happily, we don't hear companies such as Apple or Google criticising Chandler Project history whilst embracing/enjoying CalDAV. I suspect that - however well written the book may be - a *focus* on a space in time (however short or long) has overlooked the broader value of the Project.
  • Graham Perrin on 22 Dec 08
     
    I'll rate and review this book, probably some time around Christmas.

Yet the art of creating it continues to be a dark mystery, even to the experts, and the greater our ambitions, the more spectacularly we seem to fail. … [this book] sets out to understand why, through the story of one software project -- Mitch Kapor's Chandler, an ambitious, open-source effort…

      We should be more explicit about subscriptions. I guess that this statement refers to your Chandler Desktop subscriptions to the Chandler collections of other users of Chandler.

    My interest in this is two-fold: 1. interop - for example, how spheres may appear to iCal and other CalDAV clients; 2. look and feel - I have some ideas.
