Coupling mechanism
The Web pages that comprise the user interface are generic. However, an unchanging Web page cannot reflect the dynamics of a negotiation.
The dynamics inherent in the process manifests itself in two ways:
- different Web pages must be displayed to the user in response to different actions, and
- the contents of a given Web page itself must adapt to the latest situation.
<INEG> tags: HTML-like tags in the Web pages that are understood by the INSPIRE programs.
For example <INEG>user_id</INEG> - the name of the user accessing the system.
