## One toolkit, the complete local workflow

<div class="feature-grid">

<div class="feature-card">
  <h3>Model RDF precisely</h3>
  <p>Validated IRIs, blank nodes, literals, triples, quads, default graphs, and named graphs give applications a clear data contract.</p>
</div>

<div class="feature-card">
  <h3>Own the data lifecycle</h3>
  <p>Choose an in-memory model or a durable local store with atomic transactions, explicit sync, read-only access, and portable N-Quads backups.</p>
</div>

<div class="feature-card">
  <h3>Query with SPARQL</h3>
  <p>Run ASK, SELECT, CONSTRUCT, DESCRIBE, and Update. Consume large result sets as lazy iterators instead of materializing them all at once.</p>
</div>

<div class="feature-card">
  <h3>Stream standard formats</h3>
  <p>Read and write Turtle, N-Triples, N-Quads, TriG, and RDF/XML with explicit syntax and import-failure semantics.</p>
</div>

</div>

## 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.

!!! info "Compatibility claims are evidence-scoped"

    Oxiland provides Redland-shaped workflows. Tip **0.9** ships an expanded C
    **source-compat preview**—not an ABI drop-in for existing `librdf`
    binaries, and not an rdflib adapter. Start with the
    [positioning guide](evaluators/positioning.md) and verify each claim in the
    [parity ledger](parity.md).

### Build your first dataset

Choose the language you already use. Both tracks cover installation, models,
RDF I/O, SPARQL, persistence, failure handling, and production operations.
