Graph Validation Report

Expanded concept graph

• Nodes: 36
• Edges: 41
• Isolated graph nodes: 0

Source-only nodes

These nodes have outgoing edges but no incoming edges. This is normal for root/source concepts.

• ecc: Engineered Cementitious Composites
• processing_rheology: Processing rheology
• direct_tension: Direct tensile test
• mechanical_properties: Mechanical properties
• impact_resistance: Impact resistance
• R_ECC: Reinforced ECC
• green_ecc: Green ECC
• SIMSS: SIMSS
• applications: Applications
• multifunctional_ecc: Multifunctional ECC

Sink-only nodes

These nodes have incoming edges but no outgoing edges. Some are acceptable outcomes, but many need outgoing interpretation edges.

• resilience: Structural resilience
• sustainability: Sustainability
• embodied_carbon: Embodied carbon
• building_infrastructure: Building infrastructure
• transportation_infrastructure: Transportation infrastructure
• water_infrastructure: Water infrastructure
• smart_infrastructure: Smart infrastructure

Content nodes not yet represented in expanded graph

These Markdown node files exist but are not yet included as graph node IDs. Add them in the next graph refinement if they are important.

Validation conclusion

The expanded graph is useful as a high-level backbone, but it is not yet a full graph of all Atlas nodes. The next graph refinement should add application-specific nodes, test-specific nodes, and durability/sustainability subnodes that currently exist as Markdown files but are not represented in the graph.
