A great xKat course isn’t just a sequence of lessons — it’s a well-formed knowledge graph. As a creator, you design the nodes and the prerequisite relationships that connect them.

​
Nodes

Each node is a focused, self-contained skill or concept. Smaller, sharper nodes make for better roadmaps and easier reuse. Aim for one clear idea per node.

​
Prerequisite relationships

Connect nodes with REQUIRES edges to express order:
  • An edge from A → B means a learner should complete B before A.
  • These edges are what let MyRoads compute a correct learning path and what learners explore in the 3D graph.

​
Design tips

Keep nodes atomic

One concept per node makes prerequisites cleaner.

Model real dependencies

Only add a REQUIRES edge when it’s genuinely a prerequisite.

Avoid cycles

Prerequisites should form a forward-moving path, not loops.

Let AI help

AI Import and the V4 Generator can propose an initial node structure.

Under the hood

Published graphs are synchronized to a Neo4j knowledge graph. See Knowledge Graph Architecture for how that works.
