<p class=MsoNormal>Jesse,<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>Before I commence too far on this, I want to clear it with
you first and make sure no one else isn&#8217;t already working on it.
Basically, I&#8217;ve been looking at the latest improvements to the trunk,
T::D, and the new JDBI plugin system and I think making ModelClass and
ModelClassColumn into mixins and moving both into a ModelClass plugin seems
like the logical next step.<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>I think this would solve a few issues:<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='font-family:Symbol'><span style='mso-list:Ignore'>&middot;<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span></span><![endif]>Permissions are a problem. How do we regulate who/when
an application is able to create models, update columns and such? With a mixin,
this would be up to the application developer.<o:p></o:p></p>

<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='font-family:Symbol'><span style='mso-list:Ignore'>&middot;<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span></span><![endif]>This makes adding &#8220;proprietary mojo&#8221;
easy. For example, the CAS+ class has a Profile model that associates
additional information with the database backed models. Profile could just be
the database backed model with extra information if ModelClass was a mixin. The
same goes for ProfileProperty and ModelClassColumn.<o:p></o:p></p>

<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='font-family:Symbol'><span style='mso-list:Ignore'>&middot;<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span></span><![endif]>It also means that an application might have
multiple ModelClass objects for different purposes.<o:p></o:p></p>

<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='font-family:Symbol'><span style='mso-list:Ignore'>&middot;<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span></span><![endif]>I think this could help make the merge of the
V-M branch with the trunk happen sooner.<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>Another plugin could be provided to give a basic implementation
of these two mixins without additional program (e.g., the ModelBuilder plugin,
which provides the UI to match).<o:p></o:p></p>
