Summary

Semantic Web technologies can effectively integrate heterogeneous data sources

The Engineering Knowledge Base (EKB) provides Semantic Web based methods for data integration

AutomationML Analyzer relies on EKB as part of knowledge transfer to company partner

Semantic Web technologies used as basis for semantic search solutions at Siemens A.G.

Use of Linked Data technologies enables move towards a “Web of Engineering Data”
