This paper describes an example regarding the terminology of Islamic pottery artefacts in Portuguese and Spanish in the context of an ongoing Ph D project. The approach followed in this paper places knowledge representation at the core of terminology work. More specifically, the development of an ontology, i.e. a formal and computational conceptualisation, enables the integration of a multilingual termbase in the semantic web as linked data, targeted at experts and students of archaeology. This approach allows for the preservation of linguistic diversity, as reflected by the different linguistic practices engaged by Portuguese and Spanish archaeologists in scholarly communication.
