You can choose one or several viewpoints under which Troeps will perform classification of the mentionned object.
The result of this process is a diagnosis of the classes under which the object can be attached for each viewpoint. This result is displayed on the taxonomy by coloring the classes where the classification was processed (i.e. the subtree rooted at the class to which the object is currently attached). The colors can be interpreted as such:
The process does not attach itself the object to the classes (moreover, there can be sevaral different minimal classes under which the object could be attached). Attachement is up to the user. Attachement is an editing feature, so it is only possible in edition-enabled server under the edit mode. It can be achieved through the "Attach" button of the object edition panel or the object modification pannel.
