abstract = {The Unified Modeling Language (UML) is one of the
|
|
few modeling languages that is widely used in
|
|
industry. While UML is mostly known as diagrammatic
|
|
modeling language (e.g., visualizing class models),
|
|
it is complemented by a textual language, called
|
|
Object Constraint Language (OCL). OCL is based on a
|
|
three-valued logic that turns UML into a formal
|
|
language. Unfortunately the semantics of this
|
|
specification language, captured in the "Annex A" of
|
|
the OCL standard, leads to different interpretations
|
|
of corner cases. We formalize the core of OCL:
|
|
denotational definitions, a logical calculus and
|
|
operational rules that allow for the execution of
|
|
OCL expressions by a mixture of term rewriting and
|
|
code compilation. Our formalization reveals several
|
|
inconsistencies and contradictions in the current
|
|
version of the OCL standard. Overall, this document
|
|
is intended to provide the basis for a
|
|
machine-checked text "Annex A" of the OCL standard
|
|
targeting at tool implementors.},

abstract = {At its origins, OCL was conceived as a strict
|
|
semantics for undefinedness, with the exception of the
|
|
logical connectives of type Boolean that constitute a
|
|
three-valued propositional logic. Recent versions of
|
|
the OCL standard added a second exception element,
|
|
which, similar to the null references in programming
|
|
languages, is given a non-strict semantics.\\\\In this
|
|
paper, we report on our results in formalizing the
|
|
core of OCL in higher-order logic (HOL). This
|
|
formalization revealed several inconsistencies and
|
|
contradictions in the current version of the OCL
|
|
standard. These inconsistencies and contradictions are
|
|
reflected in the challenge to define and implement OCL
|
|
tools (e.g., interpreters, code-generators, or theorem
|
|
provers) in a uniform manner.},
