Changes
A change is defined by two events:
<ol>
<li>list item A1When the object changes the UpdateTimeStamp is set. An object is meant to be changed when at least one of its properties has been changed. To know this every property will be asked if it has been changed or not (properties hold this information by themselves). A change of a property means either:
<ol style="list-style-type:lower-alpha">
<li >list item B1it’s value has been changed (the property knows its new and old value),</li> <li>list item B2it’s ValidationTimeStamp has be set</li> </ol>continuing list item A1
</li>
<li>list item A2When a new primary child is added to a relation. Primary in this context means the first level of object relation, the directly connected object so to say. That means adding such a child counts as a change for the owner object and the UpdateTimeStamp will be set. A child can be anything (Attributes, Relationdata, etc).</li>
</ol>
