VML is a programming language proposed by discovery scientists for the
purpose of assisting the process of knowledge discovery. It is a
non-trivial extension of ML with _hypothetical views_. Operationally,
a hypothetical view is a value with a representation that indicates
how the value was created. The notion of hypothetical views has
already been successful in the domain of genome analysis, and known to
be useful in the process of knowledge discovery. However, VML as a
programming language was only informally defined in English prose, and
indeed found problematic both in theory and in practice. Thus, a
proper definition and implementation of VML with formal foundations
would be of great help to discovery science and hence corresponding
domain sciences.
...We also present a real
implementation of VMlambda, written in Camlp4 as a conservative
translator into OCaml. This implementation makes extensive use of
labeled arguments and polymorphic variants -- two advanced features of OCaml that originate in OLabl.
