Summary

This paper proposes a composable trust infrastructure for manufacturing knowledge graphs, integrating SHACL validation, PROV-O provenance, bi-temporal versioning, and graph-native decision objects. These four capabilities combine to provide emergent trust properties like full-chain auditability across heterogeneous industrial data.

Manufacturing knowledge graphs, which integrate data from diverse industrial systems, often suffer from a "trust deficit." Users struggle to verify data validity, its state at the time of a decision, its origin, or how it was acted upon. This research introduces a composable trust infrastructure designed to address these challenges. The proposed infrastructure integrates four key trust capabilities: SHACL validation for data quality, PROV-O for provenance tracking, domain-aware bi-temporal versioning for historical context, and graph-native decision objects for traceability. These capabilities are designed to compose through shared correlation identifiers, such as entity URIs and ingestion activity IDs, to produce emergent trust properties that no single component could deliver alone. An experimental evaluation confirmed that all four capabilities are equally essential, with removing any one causing specific composition queries to fail. The infrastructure was validated on a testbed integrating eleven industrial sources, demonstrating its ability to provide full-chain auditability with efficient execution. This system offers a robust framework for building trustworthy and auditable knowledge graphs in complex manufacturing environments.

Why it matters

For manufacturing and IT professionals, this infrastructure provides a blueprint for building highly trustworthy and auditable knowledge graphs, essential for data-driven decision-making and regulatory compliance in complex industrial settings.

How to implement this in your domain

  1. 1Evaluate existing data integration strategies for manufacturing knowledge graphs against the proposed trust capabilities.
  2. 2Implement SHACL validation to ensure data quality and adherence to ontological constraints.
  3. 3Adopt PROV-O or similar standards for tracking data provenance across all integrated systems.
  4. 4Design and integrate bi-temporal versioning into knowledge graph data models for historical accuracy.
  5. 5Develop graph-native decision objects to link decisions directly to the data and context that informed them.
