<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I'm adding the architecture meta-field of VMs, Templates and Clusters in REST API (see change #16700 in gerrit). It's a read-only field (like a “final” in Java), that the administrator cannot change it, but there are
some situations where there might be a value for it, such as when an entity is received from the API, slightly modified and then its update method is called. So I would like to ask these questions about how to implement it:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">1) Should this attribute be mapped both ways (from the REST API to the engine and vice-versa)?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">2) How should this field be declared in the rdsl_metadata? Do I have to explicitly put it in the optional arguments or should I omit it?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">3) How can I make this field strictly immutable (like the ID field is), given that the architecture is a field of the CPU entity, and the methods used to check for invalid updates can only operate on fields that belong
directly to the main entity? <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal">Thanks.<o:p></o:p></p>
