Transitive Implied Relations

This category of Implied Edge Builders can be thought of as a chain of fields which collapse down to one field.

[!EXAMPLE] For example, My parent’s parent is my grandparent. This is a transitive implied relation, represented with the following syntax, [parent, parent] -> grandparent (a chain of two parent fields collapses down to one grandparent field between the start and end nodes):

flowchart LR
1(Me) -- parent --> 2(Mother)
2 -- parent --> 3(Grandfather)
1 -. grandparent .-> 3

In the settings for this relationship:

Options

• Edge Chain: The chain of fields required for the rule to match
  • [parent, parent] in the above example
• Closing Field: Once a match is found, which field closes the chain off
  • grandparent in this example
• Close Reversed: Whether the close the chain from start to finish, or vice versa
  • false (or unchecked) in this example, because it closes from start to finish
• Rounds: How many rounds to run the rule for
  • 1 in this example
• Name (optional): Give a label to the rule. By default, the [field] -> close syntax will be used.

Examples

There are many different rules you can build with this syntax

Opposite Direction

If you have to fields up and down, you can make them semantically “opposite” of one another with the following two rules (note how this rule requires the “Close Reversed” option toggled on, so that the end node points back to the start node):

[up] <- down

flowchart LR
	A -->|up| B
	B -.->|down| A

[down] <- up

flowchart LR
	A -->|down| B
	B -.->|up| A

Same Sibling is Sibling

If A and B both share the same sibling, mark them as siblings as well.

[sibling, sibling] -> sibling

graph LR
	A -->|sibling| B
	B -->|sibling| C
	A -.->|sibling| C

Siblings Parent is Parent

If A and B are siblings, then make A’s parent B’s parent, as well.

[sibling, parent] -> parent

graph LR
	A -->|sibling| B
	B -->|parent| C
	A -.->|parent| C

Parents Sibling is Aunt/Uncle

If A’s parent is B, and B is the sibling of C, then make C the aunt/uncle of A.

[parent, sibling] -> aunt-uncle

graph LR
	A -->|parent| B
	B -->|sibling| C
	A -.->|aunt-uncle| C

Parents Child is Sibling

If A and B both have the same parent, mark them as siblings.

[parent, child] -> sibling

graph LR
	A -->|parent| B
	B -->|child| C
	A -.->|sibling| C

Cousin is Sibling

If A and B are cousins, mark them as such.

[parent, sibling, child] -> cousin

graph LR
	A -->|parent| B
	B -->|sibling| C
	C -->|child| D
	A -.->|cousin| D

Bulk Add Rules

You can also add transitive rules in bulk, using the syntax shown above ([field-one, field-two] -> close-field). To do so, scroll down to the bottom of the Transitive Implied Relations settings and open the “Bulk Add Rules” dropdown. Then, paste a new-line separated list of rules into the input area, and click “Bulk Add”.
