Abstract-Researchers in digital humanities have for many years been producing online editions of texts based on TEI XML, a widely-adopted standard for marking up textual resources with semantic content. However, this has led to a certain isolation of information, the so-called 'digital silo', and such modes of digital publication have not always made best use of the possibilities of digital technologies. The model is also challenged by the need to model texts that are by their very nature interconnected. The paper describes a collaborative environment of tools and techniques for working with texts that allows scholars to work with such highlyinterconnected material.
