I don't know that we've reached any consensus yet but I'll take a
stab at some assertions and we'll see if anyone objects:
- Entity<T> and Representation<T> should only be used in examples
when the functionality they offer is required, where possible
examples should use the bare T
- Entity<T> could be replaced in all instances by a more granular
approach, e.g. we could define a @MediaType annotation for method
parameters that would cause the value of the Content-Type request
header to be passed as the value of the annotated parameter.
- Regardless of whether Entity<T> is retained or not we need a
general purpose mechanism to access request information - said
another way we shouldn't have to define a separate annotation for
each piece of metadata.
- Representation<T> is useful for cases where metadata can't be
determined statically
- For cases where metadata can be determined statically then
annotations should be used instead of Representation<T>. Two
approaches are possible: annotate the type and/or annotate the usage
of the type. Of the two approaches, the latter is more flexible since
it can be applied to types outside the control of the user.
- We need a standard mechanism to plug-in [de]serializers for
arbitrary user-defined types. The JSR specification will define a set
of types that will be supported without user supplied [de]serializers.
