<div>Mike, </div>
<div><br>
</div>
<div>Like I proposed in my previous email about the model and the APIs, </div>
<div><br>
</div>
<div>About the InstanceGroupPolicy, why not leave it as is, and introduce a new abstract model class called Policy. </div>
<div>The InstanceGroupPolicy will be a reference to a Policy object saved separately. </div>
<div>and the "policy" field will point to the saved Policy object's unique name or id. </div>
<div><br>
</div>
<div>The new class Policy – can have the usual fields – id, name, uuid, and a dictionary of key-value pairs for any additional arguments about the policy. </div>
<div><br>
</div>
<div>This is in alignment with the model for InstanceGroupMember, which is a reference to an actual Instance Object saved in the DB. </div>
<div><br>
</div>
<div>I will color all the diamonds black to make it a composition I the UML diagram. </div>
<div><br>
</div>
<div>Thanks,</div>
<div>Yathi. </div>

<div><font size="2" face="sans-serif">Could we agree on the following small changes to the model you posted last week?</font><br>
<br>
<font size="2" face="sans-serif">1. Rename InstanceGroupPolicy to InstanceGroupPolicyUse</font><br>
<br>
<font size="2" face="sans-serif">2. In InstanceGroupPolicy[Use], rename the "policy" field to "policy_type"</font><br>
<br>
<font size="2" face="sans-serif">3. Add an InstanceGroupPolicyUseProperty table, holding key/value pairs (two strings) giving the properties of the policy uses</font><br>
<br>
<font size="2" face="sans-serif">4. Color all the diamonds black</font> <br>
<br>
