 Open Issues/To-Do Items  Open Issues/To-Do Items
   
  Targeted for 0.5 Final Release   Targeted for 0.5 Alpha 1
   
       * Fix issue w/reading XMI 1.1 files where metamodel has nested packages
   
       * Clean up __class_provides__ so that it isn't just something randomly
         poked in by binding.Once(); it needs a clean infrastructure/interface.
   
       * Refactor "Pythonic" UML 1.3 extensions so they're usable for most
         MOF-aligned metamodels (e.g. all UML and CWM versions)
   
       * Remove deprecated items from peak.model: Feature, Reference, Package,
         Model, Namespace, DataType, etc.
   
       * Get XMI writing in place, w/transaction support
   
       * Updated reference docstrings for 'peak.api', 'peak.binding',
         'peak.config', 'peak.exceptions', and 'peak.naming'.
   
       * Finish tutorial chapter 2 (?)
   
    Targeted for 0.5 Alpha 2
   
       * On-the-fly class combination (think "runtime module inheritance",
         without the modules) for DMs.
   
       * 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.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.
   
       * 'peak.naming' refactorings: 'peak.model'-based syntax utilities for
          creating address syntaxes.
   
    Targeted for 0.5 Final Release (or sooner)
   
     General      General
   
       * Update tutorial documentation          * 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
   
           - useful example "flat" naming context (e.g. like AppUtils.URLkeys)
   
           - useful example hierarchical naming context (e.g. like JNDI's LDAP
             context or filesystem context)
   
           - 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?
   
       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?
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
     Database  
   
       * Create test suite to check proper transactional functioning, cache  
         consistency, queueing behavior, and typemap management.  
   
       * Update Interfaces to reflect current API, and document internals

     (Note: some of the below is held-over from TransWarp and may no longer be
     relevant as written, they are being kept on this list as placeholders for
     ideas or problem areas that may need to be re-considered in future.)

   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  
   
     * Persistent SEF module, with Base.__getstate__ supporting omission  
       of Once attributes, and DynamicBinding setting _p_changed on  
       instantiation.  
   
     * 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.  
   
     * Helper methods in Elements & Services for marshalling, common queries, etc.  
   
     * Generator framework  
   
       - Tagged values in stereotypes vs. main values?  
   
       - Should tagged values be copied directly into templates?  Treated as  
         Python expressions?  
   
       - Should Services be generated using an Element class' "static"  
         (class-scope) methods/attributes?  
   
         - Are association-ends scoped?  
   
         - Would it be better to seperate them?  
   
       - What determines whether an implemented Service actually stores objects  
         or delegates this to its subclass services?  
   
     * Simple Zope product demo (upload XMI, then browse the model via the web)

     * UUID/GUID support          - Would it be better to seperate them?
   
     * Support for advanced references, external references?        - What determines whether an implemented Service actually stores objects
           or delegates this to its subclass services?
   
     * XML Namespaces (do any current XMI tools need this?  Which spec version      * Simple Zope product demo (upload XMI, then browse the model via the web)
       requires this?)  
   
     * DOM StructuralModel (so files can be edited without affecting vendor XMI  
       extensions)
