There is a growing interest in information systems implemented as Internet-based software artefacts. Little attention has been paid to a comprehensive picture of such artefacts and their difference in relationship to traditional software artefacts. This paper presents an analysis of the Internet-based software artefact in order to expose differences from and similarities to traditional information systems. The analysis is based on Organizational Semiotics and the concept of actability focuses on user requirements as a basis for information systems development.
