VitalGraph
VitalGraph is a high-performance knowledge graph database and client library built on PostgreSQL with full SPARQL 1.1 support.
Installation
VitalGraph offers flexible installation options depending on your use case:
Client Only (Default - Lightweight)
For applications that only need to connect to existing VitalGraph servers:
pip install vital-graph[client]
This installs dependencies for the VitalGraph client library:
- Basic RDF processing (rdflib, PyLD)
- Advanced graph processing (pyoxigraph)
- AI capabilities (openai)
- HTTP client (httpx, aiohttp)
- Configuration management (PyYAML, pydantic)
- CLI tools (click-repl, tabulate)
Server Installation
For running a complete VitalGraph server with database capabilities:
pip install vital-graph[server]
This includes all server dependencies:
- FastAPI web framework and uvicorn server
- PostgreSQL drivers (psycopg, asyncpg)
- Database ORM (SQLAlchemy, alembic)
- Vector database support (pgvector)
- Authentication (PyJWT, email-validator)
- ML/vectorization (torch, transformers, sentencepiece)
- Fuzzy search (rapidfuzz, jellyfish, datasketch)
Development Setup
For development with all tools:
pip install vital-graph[dev]
Includes pytest, black, mypy, and other development tools.
Full Installation
For everything:
pip install vital-graph[all]
Custom Combinations
You can combine multiple extras:
pip install vital-graph[client,dev]
pip install vital-graph[server,test,docs]
Quick Start
Client Usage
from vitalgraph.client import VitalGraphClient
# Initialize client with config file
client = VitalGraphClient("path/to/config.yaml")
# Connect to server
await client.open()
# Execute SPARQL queries
results = await client.sparql.query("SELECT ?s ?p ?o WHERE { ?s ?p ?o } LIMIT 10")
# Close connection
await client.close()
Server Usage
# Start VitalGraph server
vitalgraphdb
# Or with custom config
vitalgraphdb --config /path/to/vitalgraphdb-config.yaml
Data Import/Export
# Import RDF data (N-Triples, N-Quads, Turtle, JSONL, VitalSigns Block)
vitalgraphimport -s my_space -f data.nt
vitalgraphimport -s my_space -f entities.vital --format vital
# Export RDF data
vitalgraphexport -s my_space -f backup.nq
vitalgraphexport -s my_space -f entities.vital --format vital --entity-type-uri urn:PersonEntity
# See all options
vitalgraphimport --help
vitalgraphexport --help
Import/export is also available via the REST API (/api/data/import, /api/data/export) and the frontend Data Management page.
