All new child nodes need to be attached to the node that holds the immediate prerequisite information. Users must first find or add the parent node that contains the immediate prerequisite information for the child node they want to add.

1.Find the Immediate Prerequisite (Parent Node)

To edit a node's parent links, first, click on the "View parent and child nodes" button. Then, click on the "Link to an existing parent" button at the bottom right-hand side of the node, above the "cancel" and "propose" buttons. Then, click on the parent you would like to link to.

To delete a parent link, first, choose a new parent, then click on the garbage can icon below the parent link you would like to delete.

Editing a Node's Parent Links

A node is a parent of a child node when the parent's content is a direct, immediate prerequisite for learning the child node. A node can have multiple parents and can also be the parent of multiple child nodes.

Types of Relationships Between Nodes in 1Cademy Knowledge Graph

A node is a descendant of another node if the latter node contains indirect prerequisite information that is necessary for learning the content of the current node. For example, if node A is a child of node B and node B is a child of node C, then node A is a descendant of node C. Any children or descendants of node A are also descendants of node C.

Descendants of a Node on 1Cademy

A node is a sibling of another node when the two nodes share a parent node. A node can have multiple siblings. 

Siblings of a Node on 1Cademy

A node is an ancestor of another node when it contains indirect prerequisite information that a user must understand to learn the current node. For example, if node A is a parent of node B, and node B is a parent of node C, then node A is an ancestor of node C. Any parents or ancestors of node A are also ancestors of node C.

Ancestors of a Node on 1Cademy

A node is a child of another node when the latter (its parent) contains direct prerequisite information that a user must understand to be able to learn the child node. A node can have multiple child nodes and can be a child to multiple nodes.
