Release status

This documentation tip describes 0.13.0 (the current published package version). Pin installs as oxiland = "0.13.0" / pip install oxiland==0.13.0, or use a git/path checkout for unreleased tip APIs.

Oxiland

Typed RDF, SPARQL, and local persistence—without a database server.

Build linked-data applications with validated terms, named graphs, SPARQL 1.1, streaming I/O, and an embedded durable store inside your process.

Start with Python Start with Rust

Apache-2.0 OR MIT Rust 1.87+ Python 3.10–3.14

from oxiland import Model, load, query

graph = Model()
load(
    graph,
    '<alice> <name> "Alice" .',
    "turtle",
    base_iri="https://example.com/",
)

assert query(graph, "ASK { ?s ?p ?o }")

Safe, typed APIs Local persistence SPARQL 1.1 Streaming RDF I/O

Suite-wide faster-than-Redland authorized

Tip closed the ADR-028 competitive-parity gate and the ADR-029 suite-wide faster-than-Redland gate (Linux, macOS, and Windows × three independent strict runs). See the performance guide and the 0.13 report for claims policy and tables.

One toolkit, the complete local workflow¶

Model RDF precisely

Validated IRIs, blank nodes, literals, triples, quads, default graphs, and named graphs give applications a clear data contract.

Own the data lifecycle

Choose an in-memory model or a durable local store with atomic transactions, explicit sync, read-only access, and portable N-Quads backups.

Query with SPARQL

Run ASK, SELECT, CONSTRUCT, DESCRIBE, and Update. Consume large result sets as lazy iterators instead of materializing them all at once.

Stream standard formats

Read and write Turtle, N-Triples, N-Quads, TriG, and RDF/XML with explicit syntax and import-failure semantics.

Ready for more than a demo¶

Oxiland is an embedded library, not a hosted database. Your application owns the store path, permissions, process lifecycle, capacity, backups, and network boundary. The production guides turn those responsibilities into an operating model.

Positioning · Compatibility evidence

Compatibility claims are evidence-scoped

Oxiland provides Redland-shaped workflows. Tip 0.13 retains the frozen 0.11 source/binary compatibility evidence and authorizes suite-wide faster-than-Redland under ADR-029; it is not an rdflib adapter. Start with the positioning guide and verify each claim in the parity ledger.
