SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enables cross-domain querying to orchestrate reliability data and prognosis functions, allowing automated calculation of Remaining Useful Life (RuL) for gearbox components without manual data stitching.

Core Features & Use Cases

  • Federated SPARQL queries across OEM reliability data and prognosis service assets.
  • VIN-based selection to target specific vehicles and gearboxes.
  • Integration with EDC connectors and knowledge graphs to trigger RuL calculations and return results.

Quick Start

Provide a list of VINs to compute RuL for GearBox using the federated SPARQL skill.

Frequently Asked Questions about RuL Federated SPARQL Skill

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I calculate Remaining Useful Life for gearboxes across federated data sources?▼

To calculate Remaining Useful Life, a federated SPARQL query orchestrates OEM reliability data and prognosis function services across EDC connectors. It targets specific VINs to compute gearbox RuL without manual data stitching.

What SPARQL version is needed for cross-domain queries over EDC connectors?▼

Cross-domain querying over EDC connectors requires SPARQL 1.1 federation. This version provides the federation capabilities needed to bind knowledge graphs and invoke RuL calculation assets.

Can I query prognostics for specific vehicles using VINs in a federated knowledge graph?▼

Yes, VIN-based selection targets specific vehicles and gearboxes within the federated query. The skill uses cx-behaviour and cx-reliability ontologies to query registered graph assets and return prognosis results.

Do I need registered graph assets to run federated SPARQL queries for prognosis?▼

Yes, registered graph assets are required to invoke the RuL calculation. The federated SPARQL query relies on these assets, bound via EDC connectors, to access OEM reliability data and prognosis services.

What is the best way to automate RuL prognosis without manually stitching reliability data?▼

The best way to automate RuL prognosis is using federated SPARQL queries to orchestrate reliability data and prognosis functions. This eliminates manual data stitching by binding data provider and calculation service assets across domains.

Why does my federated SPARQL query fail to return gearbox prognosis results?▼

Federated SPARQL queries fail when required ontologies like cx-behaviour or cx-reliability are missing, or when graph assets are not properly registered in the EDC connectors to invoke the calculation service.
