Knowledge Graph Loader
Software componentKnowledge & DataKnowledge & Dataarc:KnowledgeGraphLoader
A software component that idempotently writes extracted entities and relationships into the knowledge graph in batched transactions.
Responsibility. Idempotently populates the graph with extracted entities and relationships.
Also known as: Graph Populator, Knowledge Graph Builder

receives data from dynamic
is constrained by control
Design guidance
- MUST use create-or-update (merge) semantics so repeated runs over overlapping documents do not create duplicates.
- MUST merge on immutable identifiers only and set mutable attributes separately.
- SHOULD write in bulk transactions over document batches rather than per document.
Quantitative guidance
As stated by the sources; verify before use.
- Process documents in batches of 100-1000 before bulk writes to the graph (Ch1.7A).
