This paper reports on the construction-based Treebank currently under development in the frame-work of the Ramses Project, which aims at building a multifaceted annotated corpus of Late Egyptian texts. We describe the specifications that have been implemented and we introduce the syntactic formalism and the related representation format that are used for the syntactic annotation. Further-more, the annotation scheme is discussed with particular attention paid to its evolutionary nature. Finally, we explain the methods as well as the annotating tool, called SyntaxEditor; we conclude by addressing the question of forthcoming developments, especially the search engine and a context-sensitive parser.
