- **Event (L1):** An update to the graph state (changes to node/edge properties or graph topology) resulting from the application of update rules. - **Sequence (L1):** An ordered series of graph state updates. - **Information (L1):** Distinguishability between graph states or sub-graph configurations. - **Pattern/Structure (L1):** Persistent or recurring sub-graphs or configurations of node/edge states. - **Influence/Causality (L1):** Defined by connectivity and the effect of update rules propagating through the graph. - **Resolution/Context (L1):** Context is the local neighborhood of a node/edge influencing its update. Resolution relates to the granularity of state variables and interaction rules.
