If you cannot find your immediate prerequisite (parent node), you need to find the closest (ancestor) prerequisite available within the topic you are working on. Then you will need to bridge the gap between that one and the node you want to propose by proposing other parent (prerequisite) nodes.

Add/Link Immediate Prerequisites (Parent Node)

A node is an ancestor of another node when it contains indirect prerequisite information that a user should understand to be able to learn the parent nodes. 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.

Types of Relationships Between Nodes in 1Cademy Knowledge Graph

A node is a parent of another node when it contains direct (immediate) prerequisite information that a user should understand to be able to learn the following node. A node can have multiple parents and can be a parent to multiple nodes. 

Parents of a Node on 1Cademy

A node is a child of another node when a user needs to know the information in the former node to learn the current node. A node can have multiple child nodes and can be a child of multiple nodes.

Ancestors of a Node on 1Cademy

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.
