The information society develops a novel and comprehensive vision of governance with knowledge as core part. For building Knowledge Management Systems (KMS), a mere transferring of concepts from the private sector to the public area will not suffice; approaches of their own are necessary. For this purpose, Public Administration in general as well as in typical applications is juxtaposed with main features of KMS. Focal question is how features of KMS technology can meet requests derived from administrative work. The outcome is a remarkable picture showing bright options and possibilities, shortfalls and indications for further development.
