Ediarum is an editing environment designed and implemented by TELOTA at the Berlin-Brandenburg Academy of Sciences and Humanities (BBAW, Germany). It is based on two main components: an open-source XML native database (eXistDB) and a widely used commercial XML editor (Oxygen XML editor). This paper aims to present ediarum.PROHD.edit and to reflect on the most important challenges encountered during the software localization. After reviewing what “localization” means in Translation Studies (Pym, 2016; Jiménez Crespo, 2016), I will discuss the process of internationalization of the software (mostly variables written in ediarum's default functions), the localization itself (the translation of terms and descriptions displayed in the interface) and some testing undertaken with the Cuban team of Proyecto Humboldt Digital.
