In this paper we describe how multilingual linguistic and lexical information is stored and accessed within the framework of the SEMbySEM project\footnote{SEMbySEM (\url{http://www.sembysem.org}) is a research project within the European ITEA2 programme (\url{http://www.itea2.org/}). It started June 2008 and will end December 2010.}. The SEMbySEM project is dedicated to defining tools and standards for the supervision and management of complex and dynamic systems by using a semantic abstract representation. To provide the project with multilingual linguistic and lexical information and in order to achieve an appropriate, flexible, reusable and accurate representation of this information we chose the Linguistic Information Repository representation \cite{NeOn08} model and adapted it to our needs. In this paper we discuss the rationale for this choice, describe its implementation and also the employment of other linguistic standards.
