Exploring the graph of a resource

From the page, Consulting a resource, a button lets you graphically explore the links in the resource.

Exploring nodes and links

The graph displays a main node representing the resource to be explored. The graph then displays a node for each resource linked to the main resource, with an arc between each pair of nodes to materialize the link.

An arc between two nodes represents the fact that there are one or more links between the two resources. Links can be modeling links, collaborative links, or custom links. A drop-down menu at the top right of the graph allows filtering the types of links taken into account in the calculation of the graph.

The graph automatically calculates the positions of the nodes so as to limit the overlapping of nodes and arcs. The nodes can be moved manually by drag n’ drop. The graph will then seek to further limit the overlap of graphic shapes.

A double click on a node makes it possible to ask to explore the links of the resource represented by the node and therefore to extend the graph. A second double-click on the same node reduces the graph by no longer displaying the links of the resource. You can therefore recursively browse the links between resources.

Viewing resource properties

Selecting a node displays the properties of the corresponding resource in the right-hand area: its properties, links, and comments.

Selecting an arc displays the list of links represented by this arc.

Moving the mouse over a node displays a toolbar that allows you to:

Zoom feature on the graph

You can zoom in or out in the graph using the mouse wheel.

Note that a button on the toolbar can be used to hide the box on the right side of the page. This function is especially useful in case you want to save space to display a graph with many nodes.
