Project Note

The Site

  • Content
The issue of the site is law and electronic commerce in Australia and Germany. The site contains a limited number of links which are listed in four categories: 
 -Primary Material 
 -Secondary Material 
 -Digital Cash 
The primary material category contains links to legislation. 
The secondary material category contains links to legal publication about electronic commerce. 
The links category contains links to institutions which provide useful information about legal issue in electronic commerce. 
The digital cash category contains links about electronic money and other payment systems. This has been done to provide some links to a more specific issue. 
It was not intended to provide an extensive number of links, but only a couple of particularly interesting links. I rather intended to provide a model for structuring a page about a comparative legal issue. 
  •  Design
The page had to be designed solely with Netscape Composer. The main structure of the page was created by using various tables. Tables at the top and the bottom of each page contain links to important pages of the site. The table at the left is a navigation bar, which can be used to browse to all pages of the site. The use of colours has been reduced to a minimum and the use of pictures has been totally avoided. This has been done in order to keep the site simple and accessible. 
A Java application has been used to indicate the last update of the site. 
  • The aide application
The aide rulebase is about Section 14 (4) of the Electronic Transactions Act 1999 (Cth). 
This means that the should decide whether an electronic communication has been received by the addressee. So far as this is possible in those circumstances in which the addressee did not designate an information system. I did originally intend to write rules covering both, subsection 3 and 4. It would then have been possible to decide whether the addressee has received an electronic communication in both cases, when he or she did designate or did not designate an information system. However this appeared not to be possible. What would have been required, as far as I can see, would have been a forwardchaining application. 
When aide is told that there is designated information system, aide should switch to the other rule. I did attempt to write a rule which would enable this, but finally gave up. The main problem seems to be that both would have the same conclusion. 
Apart from the goal rule, the rulebase contains common sense rules and an definiton of an information system. 
The common sense rules do not really work. Those common sense rule stating that an addressee is not an information system etc. do work. The others do not. However they should be working as they have the same structure as the addressee rules. On the other hand side they do not prevent aide from working, which was the case with a couple of earlier rules. Therefore I decided not to delete those rules from the rulebase. 
The goal rule is backwardchaining with the definition rule. When running the goal rule aide will ask whether there a is system which is defined as an information system in the definition rule. 
What appeared to be difficult is to use “else”, Various attempts have lead to various failures. 
Therefore I gave up to use “else.” 
The rule in its current form is working and relatively stable. The pursing is straightforward and self-explanatory.
