## Paths

|
|
We consider the completeness **not only of direct properties but also of chains of properties**, that we name *paths*, building on previous work showing that they might convey first-order information.

The left part of the screen presents **a map giving an overview of all the entities in the collection**. The coordinates are calculated by using the multidimensional projection of vectors indicating which paths are missing.

|
|
Paths which have ordinal values, or a limited number of categorical values are candidates for color coding. By default, the best covered candidate is used to colour the entities.
|
|
To help users understand the meaning of the map, the resulting map is cut into zones, and hovering a zone highlights in yellow all the paths that are missing for the cluster in this zone.

Each rectangle represents a path. They are **ordered by completeness, from top to bottom**. The slider appears when the list is higher than the screen. Hovering a rectangle displays the property or chain of properties of that path. Hovering it more than one second queries its description and displays it in the dereferencer zone (g). Clicking the rectangle opens the detailed description of the path both for the full set (d) and the selection (e).

In its closed state, a path is represented by a gray bar, which length indicates the proportion of entities in the set described by this path. The barchart drawed by all bars gives an overview, at first glance, of the distribution of paths for all entities in the set.
