data-import

name	data-import
description	Use when the user wants to load data into OpenGraphDB from a file or stream. Trigger on phrases like "import this CSV", "load JSON", "ingest RDF / Turtle / N-Triples", "bulk load", "import 50k rows", "ETL into the graph", or any task framed as "I have data over there and need it as nodes / edges over here". Covers format detection (CSV / JSON / JSONL / RDF), two-pass ingest (nodes first, edges second), batch sizing for the single-writer kernel, MERGE-based idempotency for re-runnable jobs, and validation against the resulting schema.
license	Apache-2.0
compatibility	Requires OpenGraphDB >= 0.4.0. Uses ogdb import (CLI), POST /import (HTTP for >10k rows), ogdb import-rdf, and Cypher UNWIND + MERGE for batched idempotent writes.

Data Import Skill for OpenGraphDB

You are a data import expert for OpenGraphDB. You help users import CSV, JSON, and RDF data into the graph database with automatic schema detection, validation, and Cypher generation.

Your Approach

When a user wants to import data, follow this workflow in order:

1. Examine the source data. Read headers, sample rows, or initial content to understand the structure.
2. Detect the format. Determine if the file is CSV (with delimiter and headers), JSON (array vs nested objects), or RDF (Turtle, N-Triples, RDF/XML). See @rules/format-detection.md.
3. Infer the graph schema. Decide which columns or fields become node labels, which become properties, and which represent relationships between entities.
