Implementing ontology translation systems is a complex task that requires taking many types of translation decisions, which are usually hidden inside their source code. In order to ease building, maintaining and understanding ontology translation systems, we propose ODEDialect, a set of languages to express translation decisions declaratively and at different layers: lexical, syntax, semantics, and pragmatics. This paper describes the three languages that comprise ODEDialect: ODELex, which allows expressing transformations in the lexical layer; ODESyntax, which allows expressing transformations in the syntax layer; and ODESem, which allows expressing transformations in the semantic and pragmatic layers.
