 Open Issues/To-Do Items  Open Issues/To-Do Items
   
  Targeted for 0.5 Final Release   Targeted for 0.5 Alpha 1
   
     General      * Fix issue w/reading XMI 1.1 files where metamodel has nested packages
   
         * Update tutorial documentation  
   
         * Up-to-date and complete Persistence package  
   
     peak.binding  
   
         - add binding.Acquire  
   
         - docstrings for reference      * Clean up __class_provides__ so that it isn't just something randomly
         poked in by binding.Once(); it needs a clean infrastructure/interface.
   
         - move out 'imports' module (to util? naming?)      * Refactor "Pythonic" UML 1.3 extensions so they're usable for most
         MOF-aligned metamodels (e.g. all UML and CWM versions)
   
     peak.config      * Remove deprecated items from peak.model: Feature, Reference, Package,
         Model, Namespace, DataType, etc.
   
         - Config files:      * Get XMI writing in place, w/transaction support
   
             - add "Include Files" section (?=filename)      * Updated reference docstrings for 'peak.api', 'peak.binding',
         'peak.config', 'peak.exceptions', and 'peak.naming'.
   
             - add "Utility Providers" section (interface=provider)      * Finish tutorial chapter 2 (?)
   
             - delay eval() until rule is accessed   Targeted for 0.5 Alpha 2
   
         - Change GlobalConfig to load environ and peak.ini directly,      * On-the-fly class combination (think "runtime module inheritance",
           rather than as load-on-demand rules        without the modules) for DMs.
   
         - docstrings for reference      * 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.
   
     peak.model      * '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).  App startup tools based on ZConfig and
          PEAK-style .ini files.
   
         - make Element Persistent; add support for lazy-loaded attributes      * 'peak.naming' refactorings: 'peak.model'-based syntax utilities for
          creating address syntaxes.
   
         - review XMI/Querying extensions for forward compatibility planning   Targeted for 0.5 Final Release (or sooner)
   
         - clean up TW docstrings & interfaces      General
   
     peak.naming  
   
         - move LDAP URL support to peak.storage.ldap  
   
         - move lockfile URL support to peak.running.lockfiles          * Tutorial complete through chapter 4
   
         - move factories.__init__ stuff to peak.naming.spi, loaded via peak.ini      peak.storage
   
         - move reference classes to peak.naming.names          - unit tests for more complex object scenarios: references, thunks..?
   
         - ParsedURL refactoring (fromArgs, automatic re.compile, body parsing)          - lock management interfaces/API
   
         - docstrings for reference          - docstrings for reference
   
     peak.running      peak.model
   
         - create a basic LogFile logging provider  
   
         - unit tests for daemons?  
   
         - simple daemons comparable to those in MetaDaemon?          - clean up TW docstrings & interfaces
   
         - docstrings for reference      peak.naming
   
     peak.storage          - useful example "flat" naming context (e.g. like AppUtils.URLkeys)
   
         - URLs and drivers for LDAP, gadfly, Sybase, and postgres          - useful example hierarchical naming context (e.g. like JNDI's LDAP
             context or filesystem context)
   
         - "alternate key" rack 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?
   
         - "query" rack base class(es)      peak.running
   
         - add logging to transaction error handlers          - 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 more complex object scenarios: references, thunks..?          - 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.

     * 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

     * Document version of standard used  
   
     * Metamodel identity/version checking

     * 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)
