## Paths

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

## a - 2D Map of the entities
|
|
|
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.
|
|
|

|
|
## b - Map Projection settings
|
|
|
Paths to compute the projection and map the color scale can be changed: [Adjust projection settings](Adjust-projection-settings)
|
|

## b - Zoom controls
|
|
|
|
|
|
|
|
|
## c - Path list
|
|
|
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).

When a subset is selected, its description is displayed in regard to the full set. This enables to compare, and get an overview of the main differences between the subset and the full set.

When a URI is hovered more than one second, it is dereferenced and displayed as a clickable link in this zone, together with its label or title and description. |
