sequeless-ontology is the domain ontology model for Sequeless: a core library publishing
the ontology's api and spi contracts, plus a reference adapter for translating that model
to and from OWL. It also publishes facet-core, the zero-dependency contract by which a query
layer discovers what can be filtered in a compiled ontology — the vocabulary this repository
and sequeless-filter share so that neither
depends on the other.
Requires JDK 21.

|---|---|---|
ontology-core |
org.sequeless:ontology-core |
The ontology domain core: published api/spi contracts and internal supporting types. Scaffolded; no domain types yet. |
ontology-owl-adapter |
org.sequeless:ontology-owl-adapter |
Reference adapter translating the ontology domain model to and from OWL, depending only on ontology-core's published api. Scaffolded; no adapter types yet. |
facet-core |
org.sequeless:ontology-facet-core |
The facet contract shared with sequeless-filter: what can be filtered in a compiled ontology, its type, capabilities, and the versions defining it. Zero compile/runtime dependencies, enforced by the build. See design.md and ADR 0002. |
facet-core-testfixtures |
org.sequeless:ontology-facet-core-testfixtures |
Implementation-neutral fixtures, an in-memory reference FacetSource/ConceptSource, and the reusable FacetSourceContractTest/ConceptSourceContractTest kit any adapter — including the RDF-backed one that lands later — validates itself against. Published test-support artifact; carries JUnit/AssertJ at compile scope. |
The repository root is a pom-packaged aggregator/parent (org.sequeless:sequeless-ontology)
that ships no code — it holds the single shared version, dependency management, and build
plugins. All modules are released together from that one version.
make verify # full build + tests + quality gates (Spotless, Enforcer, ArchUnit)
make test # fast unit tests only
make fmt # apply formatting (Spotless / Palantir Java Format)make verify wraps ./mvnw -B verify; the Maven wrapper is committed, so no local Maven
install is required.
Architecture decisions live under docs/adr/; normative specifications live under
docs/specs/. The facet contract's specification is
docs/specs/facet-contract/design.md — it is the source of
truth for facet-core, and is kept identical to its copy in sequeless-filter.
