       * "Assembly Events" - have a way for root components to notify subcomponents that
         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
   
         - A 'config.ZConfigurable' mixin class that gives you a 'fromZConfig()'
           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
           Zope X3 isn't on 'sys.path' at install time.
   
         - Support for 'urllib2' protocols will be added to 'peak.naming' so that
           it can be used as the basis for the ZConfig services.
   
         - App startup tools based on ZConfig files.
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
    Targeted for 0.5 Alpha 2
   
       * Fix issue w/reading XMI 1.1 files where metamodel has nested packages
   
       * Generate UML 1.4 and 1.5 and CWM 1.0 and 1.1, and add them to the
         'setup.py' package lists.
   
       * 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
          creating address syntaxes.
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
    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',      * Updated reference docstrings for 'peak.api', 'peak.binding',
       'peak.config', 'peak.exceptions', and 'peak.naming'.        'peak.config', 'peak.exceptions', and 'peak.naming'.
   
     * Additional content for the tutorial's chapter on binding      * Finish tutorial chapter 2 (?)
   
       * On-the-fly class combination (think "runtime module inheritance",
         without the modules) for DMs.
   
   
   
   
   
   
   
  Targeted for 0.5 Final Release (or sooner)  
   
     General  
   
         * Update tutorial documentation  
   
         * Up-to-date and complete Persistence package  
   
     peak.storage  
   
         - SQL cursor(joinTxn=flag) shortcut for .joinTxn()  
   
         - SQL cursor error logging, close conn on error, and rewrap errors  
           w/SQL in error object  
   
         - SQL field type conversion (should txnTime standard change?)  
   
         - LDAP field type conversion  
   
         - Rack -> DM  
   
         - "facade" DM base class(es)  
   
         - "query" DM base class(es)

           - rework smtp: to return a factory object that supports open().
             Also think about whether smtp should move elsewhere. Maybe
             there should be peak.network or peak.internet for things like
             smtp, ftp, etc contexts?

     * Review other-end-notification protocols in the light of managed storage  
       models (e.g. database Records using virtual sequence objects as fields)  
   
     * Marshalling interface in Services; implementations for Enumeration, etc.  
   
     * More S-E-F metadata: features, subclasses, svc.<->class, nested services  
   
     * A way to generate Z3 Interfaces from Feature-based specifications?

   peak.metamodels.uml  
   
     * Need to write an MMX or XMI -> Python generator, and hook it back up into  
       the UML package, since we're right now relying on a module generated  
       by code that depends on stuff which is going away.

       extensions)
