 Open Issues/To-Do Items  Open Issues/To-Do Items
   
  Targeted for 0.5 Final Release  
   
     General   Targeted for 0.5 Alpha 1
   
         * Update tutorial documentation      * Generate UML 1.4 and 1.5 and CWM 1.0 and 1.1, and add them to the
         'setup.py' package lists.
   
         * Up-to-date and complete Persistence package      * Fix issue w/reading XMI 1.1 files where metamodel has nested packages
   
     peak.binding      * Get XMI writing in place, w/transaction support
   
         - add binding.Acquire      * Document interface expected of "active descriptors" and their complements
         (e.g. __class_provides__), refactoring for cleanliness as needed.
   
         - docstrings for reference      * Updated reference docstrings for 'peak.api', 'peak.binding',
         'peak.config', 'peak.exceptions', and 'peak.naming'.
   
         - move out 'imports' module (to util? naming?)      * Finish tutorial chapter 2 (?)
   
     peak.config  
   
         - docstrings for reference   Targeted for 0.5 Alpha 2
   
     peak.model      * On-the-fly class combination (think "runtime module inheritance",
         without the modules) for DMs.
   
         - make Element Persistent; add support for lazy-loaded attributes      * ZConfig support, probably in the form of generating ZConfig schemas
         from 'peak.model' or MOF models, but maybe in the form of 'fromZConfig'
         constructor methods as well.
   
         - review XMI/Querying extensions for forward compatibility planning      * 'peak.running' refactorings: use standard 'logging' module's log levels,
          add 'logging' distro to 'peak.util' for 2.2 backward compatibility,
         - clean up TW docstrings & interfaces         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).  App startup tools based on ZConfig and
          PEAK-style .ini files.
   
       * 'peak.naming' refactorings: 'peak.model'-based syntax utilities for
          creating address syntaxes.
   
   
    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..?
   
           - lock management interfaces/API
   
           - docstrings for reference
   
       peak.model
   
           - clean up TW docstrings & interfaces
   
     peak.naming      peak.naming
   
         - move LDAP URL support to peak.storage.ldap          - useful example "flat" naming context (e.g. like AppUtils.URLkeys)
   
         - move lockfile URL support to peak.running.lockfiles  
   
         - move factories.__init__ stuff to peak.naming.spi, loaded via peak.ini          - useful example hierarchical naming context (e.g. like JNDI's LDAP
             context or filesystem context)
   
         - move reference classes to peak.naming.names          - rework smtp: to return a factory object that supports open().
             Also think about whether smtp should move elsewhere. Maybe
         - ParsedURL refactoring (fromArgs, automatic re.compile, body parsing)            there should be peak.network or peak.internet for things like
             smtp, ftp, etc contexts?
         - docstrings for reference  
   
     peak.running      peak.running
   
         - create a basic LogFile logging provider          - 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.
   
         - unit tests for daemons?          - simple daemons comparable to those in MetaDaemon, unit tests
   
         - simple daemons comparable to those in MetaDaemon?  
   
         - docstrings for reference  
   
     peak.storage  
   
         - URLs and drivers for LDAP, gadfly, Sybase, and postgres  
   
         - "alternate key" rack base class(es)  
   
         - "query" rack base class(es)  
   
         - add logging to transaction error handlers  
   
         - unit tests for more complex object scenarios: references, thunks..?  
   
         - 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.

   peak.model    peak.model
   
     * 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)
