LCA to BIM Workflow - AP III.b.3 – n8n CI workflow

This repository provides an example workflow for integrating a graph-based query backend (Apache Jena Fuseki / SPARQL) with a graphical Low-Code platform (n8n) and a CI-style PASS/FAIL gate.

What is included

• workflows/ci_epd_query_workflow.json – n8n workflow export (import into n8n)
• scripts/run_ci_epd_query.ps1 – local runner calling the webhook and writing JSON artifacts
• scripts/payload.example.json – example webhook payload
• docs/example_response.json – shortened example output (PASS)

Prerequisites

• n8n reachable at http://localhost:5678
• Fuseki dataset reachable at http://localhost:3030/ap3/sparql

Import workflow into n8n

In n8n: Workflows → Import from File → select workflows/ci_epd_query_workflow.json
Activate the workflow.

Run (local)

From PowerShell:

• Execute scripts/run_ci_epd_query.ps1
• The script calls http://localhost:5678/webhook/ci/epd-query
• Outputs PASS/FAIL and writes artifacts locally.
