This paper presents the efforts conducted to obtain a usable and open digital version in XML-TEI of one of the major lexicographic work for Taiwanese bilingual dictionaries, namely the 《國臺對照活用辭典》 Practical Mandarin-Taiwanese Dictionary, (吳 , 2000). The original dictionary was published in 2000, after decades of work by Prof. 吳守禮 (Ngôo Siu-le/Wu Shouli). We publish the resulting TEI files on Zenodo.
