glossaLAB has progressively transformed from a multilingual glossary platform into a semantically enriched environment for the interdisciplinary co-creation of knowledge. This paper critically examines its development through three major phases: glossaLAB, glossaLAB.edu, and glossaLAB.dixit, and the tight connection to other long-term projects, highlighting the conceptual and technical transitions involved. Theoretical underpinnings that frame knowledge integration in glossaLAB are analysed, and a conceptual framework is proposed that draws on established metrics of epistemological diversity, integration, veracity, and clarity. Rather than reporting empirical findings, a validation strategy is presented that will support the development of a sustainable integration model within the glossaLAB.dixit. This paper thus contributes to ongoing debates on how conceptual systems can be evaluated and guided across disciplinary frontiers in digital knowledge infrastructures.
