This paper reports work that aims to generate texts in multiple languages from ontologies following the Conceptual Reference Model
(CRM) ISO standard for conceptual models of museums. The rationale of this work is to increase users’ knowledge and interest in
the cultural heritage domain by allowing the user to select his preferable syntax presentation and influence the order of the generated
information using generation techniques and Semantic Web technologies. We chose for study a small amount of logical relations represented
in the ontology and wrote a grammar that is capable to describe them in natural language through user editing. We present the
multilingual source authoring environment, which is built upon the grammatical framework (GF) formalism and show how it is utilized
to generate multiple texts from the CRM domain ontology. The initial results comprise texts, which vary in syntax and content.
