Tenant semantic layer
Adds the semantic layer over the existing
dim_tenantsmedallion chain (staging -> intermediate -> mart already inmain). No semantic models existed yet.Files
yardi_demo/models/semantic_models/tenant_semantic_layer.yml- dbt/MetricFlow semantic model overref('dim_tenants'): tenant/property/unit/lease entities, categorical + time dimensions, and 9 metrics.yardi_demo/models/semantic_models/sem_tenants_snowflake.sql- native SnowflakeCREATE SEMANTIC VIEW SEM_TENANTSDDL plus a bootstrap cleansing view (V_TENANT_SEMANTIC_BASE) so the view works before the marts are materialized.Metrics
Population (tenant_count, current/former), delinquency/AR (delinquency_rate, delinquent_tenant_count, total_ar_balance, total_delinquent_balance, avg_balance), exposure (total_deposits_held), credit/retention (avg_credit_score, avg_tenure_months).
Validation
The equivalent logic was executed against live
Yardi (Demo)Snowflake data via the paired TQL composed view: 159 current tenants, ~25.8% delinquency, $64.3K total AR balance; current-tenants-by-region returns 6 regions with Southeast highest at $24.1K AR / 35% delinquency.Paired with ontology library patch #639.
