In this paper we present the folder server and editing environment which will support scholars, administrators and conservators to maintain secondary SGML documents, that describe, comment and refer the primary material (image or text bases etc.) across the European borders. The technical challenge of this undertaking is to cater for the diversity in specialization, organizational and cultural context, the data integrity and the adequate high precision in reference and retrieval through the Internet. On the other side, the organization of agreement on shared contents and resources at all levels raises also interesting questions. The project so far provides first solutions and serves moreover as a forum to obtain valid requirements for future extensions.
