Remarks

For Beginners: This defines the "schema" of your heterogeneous graph.

Think of a knowledge graph with different types of entities and relationships:

This metadata tells the layer what types exist and how they connect.

Edge type connections: maps edge type to (source node type, target node type).

public Dictionary<string, (string SourceType, string TargetType)> EdgeTypeSchema { get; set; }

Names of edge types (e.g., ["likes", "belongs_to", "similar_to"]).

public string[] EdgeTypes { get; set; }

Input feature dimensions for each node type.

public Dictionary<string, int> NodeTypeFeatures { get; set; }

Names of node types (e.g., ["user", "item", "category"]).

public string[] NodeTypes { get; set; }
