Change node key from int to a user-selected string

Question

I am trying to edit the xml to change the label to edges. However to identify an edge I have to get the Key - an integer - of a node, insteaf of a string that would be more convenient when having very large graphs with lots of connections. Is there a way to edit the node Key to be a string, and maniupulate it using the GUI?

Answer 1

The IDs used in GraphML to identify elements are a format-specific implementation detail and are generated on-the-fly when writing GraphML files. Thus it is not possible to specify or modify these IDs in yEd.

If you need to reliably identify your edges, create a user-defined property for edges (see "Edit" -> "Manage Custom Properties") and set appropriate unique property values for your edges.
