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

1. 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>

2. 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();
  }

}

3. Access you API

% curl -i http://localhost:8080/

HTTP/1.1 200 OK
Content-Type: text/plain
Content-Length: 12

Hello world!

4. Delve into the the docs to learn how to publish and consume your data as model-driven REST/JSON‑LD APIs…
