Common to this class of information systems is a global setting, either for its use or development process. This means clustering That it highly concerne un distributed systems / distributed computing Where the distribution is global.

- Technical architecture: What is the technical infrastructure enabling actors to collaborate?
- Support mechanisms: How are the processes of communication, collaboration, and cooperation supported?
