Metreeca/Link
Metreeca/Link is a lightweight Java framework enabling rapid development of model-driven REST/JSON APIs.
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 back-end developers from low-level chores and completely shielding front‑end 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 adapter -->
<groupId>com.metreeca</groupId>
<artifactId>metreeca-jse</artifactId>
</dependency>
<dependency> <!-- backend adapter -->
<groupId>com.metreeca</groupId>
<artifactId>metreeca-rdf4j</artifactId>
</dependency>
</dependencies>
</project>
- Write your first server and launch it
import com.metreeca.jse.Server;
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 Server()
.handler(context -> request ->
request.reply(response -> response
.status(OK)
.body(text(), "Hello world!")
))
.start();
}
}
- Access you API
% curl -i http://localhost:8080/
HTTP/1.1 200 OK
