The capture, annotation and commenting of documents in digital scholarly editions frequently necessitate a technical understanding of XML standards, such as TEI. However, we consider this approach inappropriate. Editors, such as literary scholars, should be able to focus on their content-related work without requiring a deep technical understanding of XML and specific standards governing the storage of the data. In this paper, we present a web-based WYSIWYA editor that allows the capture, annotation, and commenting of documents, such as the content of letters or postcards. The results are stored in XML with the up-to-date TEI standard. This provides an interface for exchange with other digital editions. Furthermore, we describe how integrating the WYSIWYA editor into the hermeneutic research workflow can support the work of literary scholars compared to previous approaches. Finally, we present and describe the challenges and solutions of transitioning to TEI-conformant content from previously proprietary formats.
