  Targeted for 0.5 Alpha 1   Targeted for 0.5 Alpha 2
   
     * Object name/path support in 'peak.binding'      * Finish 'protocols' breakout and prepare for possible PEP
   
     * Review possible cross-locational or "root" things like        - Add reference docs
       'PropertyName' -- should these things move to the API?  
       Or where?  They're not 'util' things, certainly.  Perhaps        - Create tutorial
       there should be a 'peak.core' module or package for things  
       that are foundational to all the packages?      * ZConfig Integration
   
         - Sample 'AdaptiveTask' classes that perform the same functions as those
           in the MetaDaemon package, integrated into the 'peak.running'
           ZConfig schema component.
   
   
    Targeted for 0.5 Beta 1
   
     * 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 (?)
   
  Targeted for 0.5 Final Release      * Web publishing framework sufficient to deploy page-based or object-
         published apps
   
       * Get XMI writing in place, w/transaction support
   
       * On-the-fly class combination (think "runtime module inheritance",
         without the modules) for DMs.
   
     General  
   
         * Update tutorial documentation  
   
         * Up-to-date and complete Persistence package  
   
     peak.storage  
   
         - URL+driver for postgres  
   
         - LDAP schema properties, SQL type mapping utilities  
   
         - Rack -> DM  
   
         - "facade" DM base class(es)  
   
         - "query" DM base class(es)  
    Targeted for 0.5 Final Release (or sooner)
   
       General
   
           * Tutorial complete through chapter 4
   
       peak.storage
   
         - unit tests for more complex object scenarios: references, thunks..?          - unit tests for more complex object scenarios: references, thunks..?
   
           - lock management interfaces/API
   
         - docstrings for reference          - docstrings for reference
   
     peak.model      peak.model
   
         - add support for lazy-loaded attributes  
   
         - clean up TW docstrings & interfaces          - clean up TW docstrings & interfaces
   
     peak.running      peak.naming
   
           - useful example "flat" naming context (e.g. like AppUtils.URLkeys)
   
         - more docs for new 'cluster' tools          - useful example hierarchical naming context (e.g. like JNDI's LDAP
             context or filesystem context)
   
         - create a basic LogFile logging provider          - 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?
   
         - unit tests for daemons?      peak.running
   
         - simple daemons comparable to those in MetaDaemon?          - 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          - 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.

      * Generate UML 1.5 and CWM 1.0 and 1.1, and add them to the

     Miscellaneous
   
       * Functional tests that access "real" databases, LDAP, etc.
   
   Simulator/Module Inheritance    Simulator/Module Inheritance
   
       * Allow 'declareModule()' to bootstrap non-existent modules; this might

         modules.

     * 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.

   peak.metamodels.xmi  
   
     * Re-org to self-contain all XMI stuff inside an _XMI sub-component/service  
   
     * Refactoring to pure S-E-F model using Persistence  
   
     * Document version of standard used  
   
     * Metamodel identity/version checking  
   
     * XMI.Writing  
   
     * Strict parsing and/or diagnostics on files that don't match the metamodel?  
   
     * UUID/GUID support  
   
     * Support for advanced references, external references?  
   
     * XML Namespaces (do any current XMI tools need this?  Which spec version  
       requires this?)  
   
     * DOM StructuralModel (so files can be edited without affecting vendor XMI  
       extensions)
