摘要：Libraries and cultural heritage institutions are increasingly making efforts to digitise their holdings for the purposes of archiving and online publication. Historical maps are a particu-larly interesting category of cultural heritage material: They are not only an illustration of ac-cumulated geographical knowledge of the time; they also draw a fascinating picture of the cultural, political, scientific, religious and mythological context in which they were created. To the trained scholar, characteristics such as the style of cartographic representation, text in-scriptions and legends, symbols and ornamental features, or specific geographical errors and misconceptions reveal a wealth of historical background information. To the student or the layperson, however, this information is not easily accessible. In this paper we propose a Web-based system that will make it possible for scholars to col-laboratively work together in the interpretation of these features. To the general user, this in-formation will become easily accessible when interpretations are made public. Thus the sys-tem represents a collaborative academic tool, as well as a showcase of academic work. Com-munity involvement, joint aggregation and filtering of user contributed as well as externally linked data, and a user interface that invites exploration constitute the cornerstones of our en-visioned system: It enables users to add annotations to the map as a whole or parts of it; it provides basic GIS features such as (approximate) collaborative geo-referencing, feature search, import/overlay and export of point and line data; and it visualises aggregated context information in the form of tag clouds which emerge around the user's mouse pointer. We de-scribe goals and functionalities we envision for the proposed system, present early proof-of-concept implementations, and discuss areas of future work
