  Targeted for 0.5 Alpha 1   Targeted for 0.5 Alpha 3
   
     * "Assembly Events" - have a way for root components to notify subcomponents that      * Refactor binding and naming frameworks to
       they are connected to a root.  This is important for things like periodic tasks,  
       GUI components, etc., that need to perform actions as soon as they are part of  
       a valid "whole".  
   
     * ZConfig Integration        - make indirection convenient (e.g. bind to looking up something from
           another binding)
   
       - A 'config.ZConfigurable' mixin class that gives you a 'fromZConfig()'        - eliminate remaining introspection/'isinstance()' checks
         constructor for your object classes, suitable for designating as a  
         section datatype in schemas  
   
       - A 'config.ZConfig' module that provides "PEAK-aware" versions of ZConfig  
         services (e.g. it will use 'peak.naming' to resolve URLs)  
   
       - ZConfig 1.0 will be distributed with the release, and installed if      * peak.binding
         Zope X3 isn't on 'sys.path' at install time.  
   
       - Support for 'urllib2' protocols will be added to 'peak.naming' so that         - Cleanup/document attribute binding interface
         it can be used as the basis for the ZConfig services.  
   
       - App startup tools based on ZConfig files.         - Attribute -> AttribDef
   
          - binding.AttribDef has an adequate docstring
   
          - Review all current usage of NameNotFound in binding and naming
            packages.  If possible, push default values closer to the point of
            retrieval.  (The idea is to minimize the possibility that an unrelated
            NameNotFound error gets hidden by a routine catching NameNotFound
            in order to return a default value.)
   
          - Ensure default __repr__'s for all bindings are acceptable
   
          - Update tutorial for current kwargs

  Targeted for 0.5 Alpha 2      * peak.web (some of this may get bumped to alpha 4)
   
     * Fix issue w/reading XMI 1.1 files where metamodel has nested packages         - default error templates, w/useful info
   
     * Generate UML 1.4 and 1.5 and CWM 1.0 and 1.1, and add them to the         - Refactor skin/layer/resource machinery so that layers can be shared
       'setup.py' package lists.           between skins (because i18n will probably want skins and that's going
            to greatly multiply memory requirements)
     * Get XMI writing in place, w/transaction support  
   
     * Generate ZConfig schemas from 'peak.model' or MOF models?  
   
     * 'peak.running' refactorings: use standard 'logging' module's log levels,  
        add 'logging' distro to 'peak.util' for 2.2 backward compatibility,  
        make daemons based on 'peak.model' (or at least define ZConfig schemas),  
        and possibly adjust cluster stuff to work off ZConfig primary and  
        generate clustertools file(s).  
   
     * 'peak.naming' refactorings: 'peak.model'-based syntax utilities for         - clean up DOMlet parse/build framework (e.g. add line number info)
        creating address syntaxes.  
   
          - A set of simple, basic form controls that handle value rendering only
            (form metadata, validation, etc. will be handled by peak.web.forms in
            a later release)
   
          - try/catch DOMlet (and related error rendering interface/framework)

Line 74 
   
   
   
  Targeted for 0.5 Beta 1  
   
     * Document interface expected of "active descriptors" and their complements  
       (e.g. __class_provides__), refactoring for cleanliness as needed.  
   
     * Updated reference docstrings for 'peak.api', 'peak.binding',  
       'peak.config', 'peak.exceptions', and 'peak.naming'.  
   
     * Finish tutorial chapter 2 (?)  
   
     * On-the-fly class combination (think "runtime module inheritance",  
       without the modules) for DMs.  
   
   
    Targeted for 0.5 Alpha 4
   
       * Transaction/storage refactorings
   
         - transaction scopes for commands and tasks
   
         - integrate locks with transactions
   
         - transactable persistent queues
   
         - DM.find()/DM.get() queries
   
   
       * peak.web
   
          - allow use of // in DOMlets' data paths, to access resource space
   
          - DOMlets for layout/region, as defined in "A layout framework":http://www.eby-sarna.com/pipermail/transwarp/2003-August/000684.html
   
          - conditional GET support (last modified/ETag) for static resources
   
          - image resources
   
          - the return of the Specialist
   
   
       * Have a way to easily in-line custom component usage (e.g. automatically
         create a subclass component with specified 'bindTo' bindings to get its
         configuration).
   
       * Implement "contextual protocols" (c.f. "object teams") and "parameterized
         protocols" (E.g. 'ListOf(IFoo)', 'MappingOf(keys=IBar,values=IBaz)')

       * Up-to-date reference docstrings for all packages
   
       * Finish tutorial chapter 2 (?)
   
       * Web publishing framework sufficient to deploy page-based or object-
         published apps

           Also think about whether smtp should move elsewhere. Maybe            Also think about whether smtp should move to peak.net?
           there should be peak.network or peak.internet for things like  
           smtp, ftp, etc contexts?  
   
     peak.running  
   
         - make 'cluster' parser complain about things that would cause  
           the clusterit tools to choke or barf on the file, or which would  
           produce ambiguous or unintended results.  
   
         - simple daemons comparable to those in MetaDaemon, unit tests  
   
         - docstrings for reference  
   
   
     peak.config  
   
         - "Rule"-oriented configuration files (section specifies component  
           rather than property name prefix), so that daemons and other simple  
           apps can be fully configured and run via a config file.  
   
     peak.util  
   
         - docstrings for reference  
   
         - more unit tests?  
   
    Targeted for version 0.6

        schema that can generate clusterit files.  And/or replace clusterit
        tools with PEAK ones.)
