Folks,

Regarding the two questions:

(a) Does standardization entail interoperability?
and (b) Can something be interoperable without being standardized?

Let us first settled what we mean by interoperability.
I will start with the following working definition of semantic
interoperability:
A model X is semantically interoperable with model Y if we know
how the meaning of the elements in X relate to the meaning of elements in Y.
If we take "meaning" in the sense of referential semantics, this means that
we can always relate in the correct manner
the referents of the model elements in X with the referents
of the model elements in Y.

With that in mind (and answering (b)), we can achieve interoperability
whenever we are able
to establish and fully understand the relation between the referents of X
and Y.

Good standards certainly facilitate that.
However, if we put the question as "standardization ENTAILS
interoperability" (question a),
the answer is clearly no.  To put it simply, this is because (among other
reasons, including non-technical ones...)
there are bad standards. Bad standards in the sense that they are not
sufficiently expressive and clear in helping
users to express their world views in terms of the standard.

There are many examples of domains with multiple standards
that it is far from obvious how to relate the meaning of things
in standard X and with the meaning of things in standard Y.
This is even the case in the so-called hard science domains.

To cite on example in heart Electrophysiogy.
In the following paper
http://www.j-biomed-inform.com/article/S1532-0464(10)00118-8/pdf
we show the difficulties in relating multiple existing ECG standards.
The paper is actually both an example of lack interoperability with
the presence of multiple standards as well as an example of
interoperability achieved with a reference ontology that is
not a standard, i.e., "interoperability without a standard".

Best,
Giancarlo
