🧩 Node Types in PET

In Pattern Existence Theory, all information is structured as nodes connected by meaningful edges. This page outlines the different node types used in the PET schema.

🔹 Object Nodes

• Represent people, places, things, or abstract concepts.
• Have a stable internal label (e.g., Dog, Fire, Justice).
• Can be connected to patterns, events, or other objects.

Example:

A child learns that "Dogs are dangerous" because their father said so.

- `id`: U123
- `source`: Father
- `time`: 2023-04-01
- `from`: Dog
- `to`: Danger
- `result`: warning
- `details`: "Father told me dogs bit him as a child"

Dog → Animal
Dog → Pet
Dog → Dangerous

🔹 Pattern Nodes

• Represent raw sensory input (visual hashes, audio frequencies, tactile signatures).
• May or may not be initially labeled.
• Linked to object nodes after association or training.

Example:

Pattern #AB12 → Dog
Pattern #98F1 → Fire Alarm

🔹 Source Nodes

• Represent the origin of information or belief:

  • Teachers
  • Books
  • Direct sensory channels (e.g., Eye1, Ear2)

• Referenced in Understanding Nodes.

Example:

Father, Book_Encyclopedia, Sensor_Eye1

🔹 Time Nodes

• Represent a specific moment or time window.
• Used to timestamp Understanding Nodes or Events.

Example:

Time_2023-10-01T08:43

🔹 Emotion Nodes (Optional)

• Represent emotional pattern responses (e.g., Fear, Trust, Curiosity).
• Can be linked to understanding or object nodes as qualifiers.

Example:

Dog → Fear (after bite)
Dog → Joy (after play)

🧠 Exist and Non-Exist Nodes

• These are nodes, not booleans.

• Used to qualify outcomes in Understanding Nodes:

  • Dog → Danger → NonExist
  • Dog → Lick → Exist
