Message sequence charts in the software engineering process

The software development process benefits from the use of Message Sequence Charts (MSC), which is a graphical language for displyaing the interaction behaviour of a system. We describe canonical applications of MSC independent of any software development methodology. We illustrate the use of MSC with a case study: the Meeting Scheduler

Multi-user publishing in the Web : DReSS, a Document Repository Service Station

Many WWW servers contain information written by several authors. These authors either need an account on the server machine, and special permissions to create information in the server space, or else the Webmaster needs to put the information in that space or allow the server to point to the author's own space. We present DReSS, a system to enable authors to deposit (and update) documents on a WWW server, using standard WWW features only. Authors do not need login permission on the server machine, ftp upload access, or even electronic mail. As the documents live in the WWW server space there is no need for the server to be able to access documents outside its space. Thus, our system will work on even the most securely shielded servers (running in a chroot environment). DReSS consists of a set of CGI-scripts and two small auxiliary programs running on the client machine. It can be used with any (HTML-2.0-capable) WWW browser, and with any WWW server. DReSS does not use special features ..
