Concepts Overview

Version: Kastor RDF SDK 0.3.0-SNAPSHOT · Kotlin 2.x · Java 21+

This section builds the semantic mental model you need to use the SDK correctly and confidently. Read these before deep API work to avoid accidental semantic mistakes.

• Glossary — definitions shared with Getting Started, Guides, and Reference (IRI, dataset, provider, shape, …).
• How documentation fits together — tutorials vs how-tos vs explanations vs reference.

If you are changing the codebase, start with Repository architecture for Gradle modules and dependency direction, then Physical repository layout for where modules live on disk. For roadmap, implementation status, and quality gates, see Project.
