International audienceMORDigital is a newly funded Portuguese lexicographical project that aims to produce highquality and searchable digital versions of the first three editions (1789; 1813; 1823) of the Diccionario da Lingua Portugueza by António de Morais Silva, preserving and making accessible this important work of European heritage. This paper will describe the current state of the art, the project, its objectives and the methodology proposed, the latter of which is based on a rigorous linguistic analysis and will also include steps necessary for the ontologisation of knowledge contained in and relating to the text. A section will be dedicated to the various investigation domains of the project description. The output of the project will be made available via a dedicated platform
