Virtualiser logical components
17.3.1 VIRTUALIZER Logical Components
The virtualiser is based on two main logical components:
•
Virtualisation Assistant
- is responsible for the object type recognition. It
extracts structural information from the digital object representation.
•
Virtualisation Manager
- collects information provided by the Assistant char-
acterizing the object under inspection as a simple or a complex. It then builds
the object hierarchical and semantic structure, allowing the user to browse and
describe the object and its nested components.
