===Refactoring Objectives===
* Task Data Refactoring
** Currently not normalized
*** Repository configuration options stored in same file
*** Configuration data is being updated upon load anyway
** Presentation information such as hidden/readonly status fields being persisted  (put with configuration?)
*** These flags could be provided by the Attribute Factory (no need to persist them)
*** Read-only can depend on permissions of the logged in user so it might need to be stored in the data model
** Need to make sure configuration data is persisted as long as there is a single task for that repository
** Attributes need to point to a field in the configuration data (e.g. milestone) that stores a list of choices
** Operations being included
*** Needed for Trac since these depend on permissions of the logged in user
** Task Data Externalization
*** Switch to XML
*** Possibly use IMemento
**** Requires dependency on UI?
*** Separate files vs. one BIG file
**** Single files: Easy to implement lazy loading, but possibly many files in a single directory
**** Alternative: Use Apache Lucene for storage
*** Consider zipping all the individual xml files together into one zip file (similar to Open Office file format ODF)
* Lazy loading [[https://bugs.eclipse.org/bugs/show_bug.cgi?id=157257 bug#157257]]
** Currently loaded at tasklist load time
** Could just have a flag indicating the existence of an offline file rather than load the data
** What does this break?
===Proposed XML Serialization===
<TaskData version="1.0" taskId="1" repositoryUrl="http://bugs.eclipse.org/bugs" repositoryKind="Bugzilla" modifiedTs="timestamp">
<Attribute id="...priority" modifiedTs="timestamp" author="rob.elves">
<Attribute id="milestone" choices="milestone">
<Comment hasAttachment="true" attachmentId="1">
  <Attribute id="...author">
    My new comment
<Attachment id="1" isObsolete="false">
  <Attribute id="...attachment_date">
*Another option is to use Lucene as a data store
==Repository Configuration==
===Refactoring Objectives===
** (option 1) Leave as responsibility of connector assuming a contract:
***Provide IMemento upon startup as an option?
***Remote configuration gathered periodically
***Always available (even if repository is deleted, configuration sticks)
***Given a configuration folder within .mylar to persist data (not ideal)
***Task data combined with configuration upon presentation rather than persistence
** (option 2) XML externalization
***Available options per id (ie. taskdata.priority --> P1, P2, P3...)
***Available options given a specific product selection <Attribute id="taskdata.components"><Value>Bugzilla</Value><Value>Core</Value>
***Hidden/readonly status for attributes?
===Proposed XML Serialization===
<GeneralOptions id="...products" hidden="false" readonly="false">
<Product name="Mylar">
  <Options id="....os">
    <Value default="true">Windows XP</Value>
