> section 11.4.3 Update An Entity
> “Key and other non-updatable properties, as well as dependent properties
> that are not tied to key properties of the principal entity, can be
> omitted from the request. If the request contains a value for one of
> these properties, the service MUST ignore that value when applying the
> update.”
> Is there a definition of what “other non-updatable properties” means
> elsewhere in the spec? I haven’t had much success finding a reference.
> I’m trying to understand this section of the spec to answer a specific
> use case:
> Is a PUT request allowed to change the odata.type of the entity?
> Clearly this is not allowed by PATCH and MERGE because they operate on
> the original object, but for PUT I’m not sure. I would like to say no,
> the entity type should not be altered in any kind of update, but since
> PUT requires complete replacement of the original entity, constructing a
> different type in its place is not beyond the realm of possibility.
> Are there OData implementations that allow changing the type of an
> entity in a PUT?
> Thoughts?
