/*
 * I've yet to investigate deeper but looks like the
 * 'JsonRepresentationWriter' that the 'StandardRepresentationFactory'
 * is initialized with uses Bean introspection to read the properties
 * and then converts them to JSON one at a time. It doesn't look at the
 * annotations, if any, on these properties and hence ignores them
 * completely. We don't want the default serialization for
 * 'LcoalDateTime', so we write out each field separately. Of course,
 * this couples the representation with the 'Slot' class such that any
 * time the class changes, the representation will have to change to.
