Graph Assembly

Once validated and transformed, the resulting records are exported and stored transiently for injection.

JSON-LD Export

The HKG model ensures that all validated data can be exported as valid JSON-LD, including:

• Proper @context
• Correct typing (@type)
• Globally unique identifiers (@id)

This guarantees compatibility with the Knowlege graph ingestion pipelines as well as other RDF based infrastructures.

Injection

Data is loaded in defined batches into the graph database (OpenLink Virtuoso) using the provided import routines. Once injected, they become part of the integrated knowledge graph. The data at this stage is defined as our ground-truth data.
