Martenweave Examples

The core repository includes examples that can be validated and indexed locally. They are small enough to inspect, but realistic enough to demonstrate the registry workflow.

Northstar Mobility Group — Synthetic Pilot

Path:

examples/northstar_mobility_pilot

Best for:

an explicitly fictional, multidomain SAP S/4HANA transformation scenario;
Business Partner/Customer, Supplier, Material, Sales, Procurement, Logistics,

and Finance relationships in one canonical model;

deterministic CSV/XLSX profiling, intentional gaps, ownership blockers,

decisions, evidence, pending proposals, and cross-domain impact; and

a connected local Workbench driven by the same canonical repository.

Run the complete reproducible workflow:

bash scripts/demo_northstar_pilot.sh

Read the Northstar synthetic pilot walkthrough for the verified results, fictional roles, limitations, screenshot, and full command sequence.

Customer / Business Partner

Path:

examples/customer_bp_model

Best for:

SAP Business Partner to Customer migration context
customer sales area and customer group examples
SAP table/field context such as KNVV-KDGRP
decisions, issues, mappings, value lists, validation rules, and impact analysis

Run:

.venv/bin/martenweave validate --repo examples/customer_bp_model
.venv/bin/martenweave build-index --repo examples/customer_bp_model --jsonl
.venv/bin/martenweave impact FEP-S4-KNVV-KDGRP --repo examples/customer_bp_model

Synthetic Customer 360 Migration Demo

Path:

examples/synthetic_customer_migration_demo

Best for:

a fully fictional, explicitly isolated demo dataset
collecting and reconciling customer evidence from Nimbus CRM, Orbit Commerce, and Ledger AR
mapping through the Atlas Migration Hub before the SAP S/4HANA target
explaining field-level mappings, value normalization, IntegrationFlow, and DataFlowStep lineage without showing client data

Synthetic local object catalogue showing the Atlas hub, Nimbus CRM, and Ledger AR field endpoints

*Synthetic demo evidence: this local, read-only viewer is generated from fictional sources only. The SYS-DEMO-* identifiers, account references, customer names, and group values are invented for explanation and test use; they are not masked production data.*

Run:

.venv/bin/martenweave validate --repo examples/synthetic_customer_migration_demo
.venv/bin/martenweave build-index --repo examples/synthetic_customer_migration_demo --jsonl
.venv/bin/martenweave trace FEP-DEMO-HUB-GOLDEN-NAME --repo examples/synthetic_customer_migration_demo
.venv/bin/martenweave impact FEP-S4-KNVV-KDGRP --repo examples/synthetic_customer_migration_demo

Supplier / Vendor

Path:

examples/supplier_vendor_model

Best for:

SAP supplier/vendor master-data patterns
LFA1, LFB1, and LFM1 field endpoint examples
gap-to-proposal workflow using a synthetic vendor extract

Run:

.venv/bin/martenweave validate --repo examples/supplier_vendor_model
.venv/bin/martenweave build-index --repo examples/supplier_vendor_model --jsonl
.venv/bin/martenweave gaps \
  examples/supplier_vendor_model/data/samples/vendor_extract.csv \
  --repo examples/supplier_vendor_model \
  --check-model

Simple Product

Path:

examples/simple_product_model

Best for:

first-time onboarding
simple table mode
small product CSV profiling
understanding domains, entities, attributes, field endpoints, and value lists

Run:

.venv/bin/martenweave validate --repo examples/simple_product_model
.venv/bin/martenweave build-index --repo examples/simple_product_model --jsonl
.venv/bin/martenweave search "product" --repo examples/simple_product_model

Generic Product

Path:

examples/generic_product_model

Best for:

non-SAP model registry use cases
generic product data model examples
system lineage and integration-flow examples

Run:

.venv/bin/martenweave validate --repo examples/generic_product_model
.venv/bin/martenweave build-index --repo examples/generic_product_model --jsonl
.venv/bin/martenweave scorecard --repo examples/generic_product_model

What Examples Are Not

The example content is not certified by SAP.
They are not customer implementations.
They are not generated indexes to preserve by hand.
They are not proof of a hosted SaaS workflow.

They are starter models for testing, learning, and contributing better scenarios.
