This paper is an extension of previous work by the authors and other researchers that studies the application of the OntoLex-lemon model for representing the InterActive Terminology for Europe (IATE) database in the Semantic Web. While traditional XML-based approaches have been effective for multilingual terminological work, the Semantic Web enables richer, more interoperable representations. The study evaluates the suitability of OntoLex-lemon for modeling IATE’s complex structure and identifies limitations in existing vocabularies. To address these, this paper tries to identify orher existing vocabularies and ontologies that could satisfy those limitations, which include term reliability, regional usage, lifecycle statuses, lookup forms, and concept cross-references. Still, some representation requirements are not covered by existing vocabularies and may need to be further discussed within the community.
