## What it is
RDFLib is a pure Python library for working with RDF (Resource Description Framework), providing parsers and serializers for formats like RDF/XML, Turtle, N-Triples, N-Quads, and JSON-LD. It includes a Graph interface with pluggable store backends and a full SPARQL 1.1 query and update implementation.

## Use cases
- parse and serialize RDF data in Turtle, RDF/XML, JSON-LD, or N-Triples
- run SPARQL queries against RDF graphs in Python
- build and manipulate RDF graphs programmatically
- query remote SPARQL endpoints
- convert linked data between RDF serialization formats
- work with ontologies and semantic web data
- store RDF triples in memory or on disk

## When to choose
- you need to parse, serialize, or query RDF in Python
- you want a pure-Python solution with no native dependencies
- you need SPARQL 1.1 query and update support
- you're building semantic web, linked data, or knowledge graph tooling

## When to avoid
- you need extremely high-performance triple stores at scale (consider a dedicated graph database)
- you want a standalone RDF database server rather than an embedded library
- you need SHACL validation or OWL reasoning (use the companion pySHACL or OWL-RL packages)

## Facets
