Metreeca/Link
Metreeca/Link is a model-driven Java framework for rapid REST/JSON-LD backend development.
Its engine automatically converts high-level declarative JSON-LD models into extended REST APIs supporting CRUD operations, faceted search, data validation and fine‑grained role‑based access control, relieving backend developers from low-level chores and completely shielding frontend developers from linked data technicalities.
Metreeca/Link is server and storage-agnostic and may be easily connected to your solution of choice.
Getting Started
- Add the framework to your Maven configuration
<project>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.metreeca</groupId>
<artifactId>metreeca-link</artifactId>
<version>${link.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<dependencies>
<dependency> <!-- server connector -->
<groupId>com.metreeca</groupId>
<artifactId>metreeca-jse</artifactId>
</dependency>
<dependency> <!-- storage connector -->
<groupId>com.metreeca</groupId>
<artifactId>metreeca-rdf4j</artifactId>
</dependency>
</dependencies>
</project>
- Write your first server and launch it
import com.metreeca.jse.JSEServer;
import static com.metreeca.rest.Response.OK;
import static com.metreeca.rest.formats.TextFormat.text;
public final class Hello {
public static void main(final String... args) {
new JSEServer()
.delegate(context -> request ->
request.reply(response -> response
.status(OK)
.body(text(), "Hello world!")
)
)
.start();
}
}
