> Ids are the primary way to reference an instance in OData; they are used in relationships, in deltas, and can take the place of instances in payloads. We recommend, but do not require that ids be dereferenceable.
> Clients need a dependable way to get from an id to a reference, whether or not the reference is dereferencable. Although they could construct a query if they know the root set the id comes from, it would be useful and more discoverable to introduce a canonical query function, at the service root, for returning an instance given its id.
> Note that, since the id is likely to contain illegal characters, we have to pass the id as a query option, and will need to double single quotes in reference
> Options:
> GET ~myservice/getbyid(@id)?@id='.....'
> GET ~myservice/$getbyid?@id='.....'
