Developer's tour of Chandler

Next Generation PIM.

Focus on making a basic project which is highly reusable and growable.

Calendar is not that far away.  Counting in Months, not years.

Reminder of the BOF

Ted Leung

    Focussed on the repository portion of the architecture
    Not just building an app, but a substrate to allow other items to access data.
    WxWidgets as portion of GUI.  WxPython binding to that.
    
    Chandler repo is next to such.  Built on SleepyCat, DbXML, pyLucene.  Query runs across all layers.
    Extensibility provided by Parcels - and a parcel loader.
    
    Secoond layer providing services for parcels - twistedPython, a scheduler manager (app scheduling).  Notification manager for interparcel comm.
    
    Content Model - 'schema' definition for items (email, task, appt).  WebDAV as a tactical choice.
    
    Chandler Repo 
    
        Item Based data
            bidirectional
        Integrated w/Python
        Schema described by XML
        Supports concurrency and threading, 
        Full Text indexed (pyLucene).  Compiled Java Lucene with Python wrapper.
        
    Services Layer
        
        Standards (IMAP/POP
        WebDAV
        XMPP
        CALDAV (http://xml.coverpages.org/ni2003-12-31-a.html)
        
    CVS, wiki (RSS)
    Mailing lists
    IRC, etc
    
Roadmap

    0.4 in Oct 2004 (Experimentally usable, calendar)
    0.5 3-5 months subsequently (basic end user usage, etc)
    1.0 'in 2004'
    
John Anderson on CPIA (Presentation and Interaction Architecture)

    Kappor, Anderson, Hertzfeld
    Thre primary goals
        Chandler specific UI building Blocks (fully conversant with Chandler types)
        Blocks independent of presentation platform
        Enable 'non-programmer' build mode.
            More fully baked blocks than most toolkits
            Blocks intercommunicate.  'Chandler Events'
        
        Block Types
            Container Blocks
            Tree. List blocks
            Compound Blocks
            
Email - Brian Kirsch
    Items become multiply referecneable and viewable
    First problem - what libraries?
        IMAP Library, Mail Parsing Library. Chose Twisted for former (and SMTO)
