Abstract. As the e-government domain is about to become a field of application for Semantic Web technologies, the actors involved still lack reasoning to decide on critical issues such as organisational cost/benefit, „user“ involvement, technical integration, and implementation strategy. Firstly, the paper seeks to identify “semantic problems” in e-government as prerequisite for discussing the requirements for the application of Semantic Web technologies. Secondly, experiences from an ongoing project are discussed to identify critical issues from the systems development perspective. Thirdly, taking into account the problems identified and the case findings, a research agenda is laid out aiming to guide and support the application of Semantic Web technologies in e-government.
