NODE (Details)

NODE (Details) describes node properties in a knowledge graph that go beyond just the name. Each node has: type (entity or attribute), name, URR classification (Unique/Root/Rare), layer (Core Unique, Strong Direct, Relevant Contextual), source (CONFIRMED/PREDICTED/SERP-ONLY), and optionally metadata (search volume, priority P1-P4). Node properties are critical for automation — pipelines can filter nodes by layer (show only Core Unique) or by source (show only CONFIRMED). In Neo4j you record properties as key-value pairs: MERGE (n:Attribute {name: 'probate', urr_type: 'ROOT', layer: 'core_unique', source: 'CONFIRMED'}). The richer the node metadata, the more precise the graph analysis.

For example, filtering nodes by layer='core_unique' AND source='CONFIRMED' gives a list of the most important, confirmed attributes to cover.

In practice, establish the property schema at the start of graph construction — adding new properties to existing nodes is easy, but changing the schema mid-project creates inconsistencies.
