Graph model

Nodal treats nodes and relationships as separate first-class POCOs. A relationship can carry its own properties and can be directed or undirected.

Attribute	Meaning
GraphNode	Maps a CLR type to a portable node label or vertex type.
GraphRelation	Maps an edge type and its direction.
GraphKey	Selects the stable domain identity.
GraphProperty	Maps a CLR property to its stored name.
GraphIgnore	Excludes application-only or calculated state.

Configuration precedence is fluent model configuration, then attributes, then conventions. Provider-only schema options belong in migrations, keeping domain types independent of Neo4j and TigerGraph.

[GraphNode("Person")]
public sealed class Person
{
    [GraphKey, GraphProperty("person_id")]
    public required string Id { get; init; }

    [GraphProperty("display_name")]
    public required string Name { get; set; }

    [GraphIgnore]
    public string DisplayLabel => $"{Name} ({Id})";
}
