Edit data: Edit properties and categories

Nodes are made of one (or multiple) categories, and a set of properties. Edges are made of one type, and a set of properties.

Properties are simple key-value pairs (e.g. name: "James", age: 31).

Node categories are used to tag a node (e.g. Company). Some graph databases (e.g. Neo4j) support multiple node categories.

Edge types are used to define the nature of an edge (e.g. FRIEND_OF).

It is a limitation of most graph databases that the type of an edge cannot be edited once the edge has been created.

Editing a node / edge

If we select a node or an edge, we can edit it by right-clicking on it or clicking on the More option in the Selection panel.

Next, we click on Edit, which will open the node or edge edit modal.

Adding, Editing or Removing a property

To add a new property, we need to fill in the name of the property and provide a value new_property, and new_property_value, for example--and click on the Add button.

To edit the new property or an existing one, we only need to change its value, and when everything is edited, click on the Save button.

To remove a property, we only need to click on the Delete button and when everything is edited click on the Save button.

The edge edit modal works exactly the same way

Adding and removing a category

Only available on nodes

To add a category to a node we need to type the desired category. After typing the first character, categories already present in the database that match it will be shown. The first option on the list is to select a new one.

To select one category (even new), we need to click on the list. If the input changes its color to green, your choice has been accepted. Next, we click on the Add button and, if we want to save the changes, on the Save button.

To remove a category, we need to click on the right side of the cross.

These changes will only be saved after clicking on the Save button.
