  • Inference (ruleset configuration): Enable inference rulesets .
  • Combination of SPARQL with MarkLogic document query: Constrain SPARQL query with MarkLogic queries.
  • Optimized pagination of SPARQL result sets: Efficient paging of results.
  • Permissions: Manage permissions on triples.

Before you start

The markLogic-rd4j API supports RDF4J v2.4.3.

Setup MarkLogic

Ensure MarkLogic 9.0-8 or greater is installed and running. To use marklogic-rdf4j applications you will need access to a running MarkLogic server.

Usage

Quick Start

The markLogic-rdf4j API is available via Maven Central.

For gradle projects, include the following dependency in your build.gradle:

dependencies {
    compile group: 'com.marklogic', name: 'marklogic-rdf4j', version: '1.2.2'
}

For maven projects, include in your pom.xml:

<dependency>
    <groupId>com.marklogic</groupId>
    <artifactId>marklogic-rdf4j</artifactId>
    <version>1.2.2</version>
</dependency>

Build and Use from develop branch

This section describes how to build and test marklogic-rdf4j API from develop branch.

Setup MarkLogic Java API Client (optional)

marklogic-rdf4j depends on MarkLogic Java API Client v4.1.2 and should pull down this version from maven central.

To optionally build marklogic-rdf4j with develop branch version of MarkLogic Java API Client:

  1. Clone or download MarkLogic Java API client develop branch.
  2. Build and deploy Java API client to local maven repo.
mvn -Dmaven.test.skip=true -Dmaven.javadoc.skip=true deploy

Verify that Java API client has been deployed to your local maven repo.

  1. Edit marklogic-RDF4J/build.gradle to use that build
    compile('com.marklogic:marklogic-client-api:4.1.2') 

Setup and Test markLogic-rdf4j API

marklogic-rdf4j depends on MarkLogic v9.0-8 or greater installed and running;

  1. Clone or download marklogic-rdf4j master branch.
  2. Review marklogic-rdf4j/gradle.properties which defines test deployment settings.
  3. Run gradle target that provisions MarkLogic with everything required (database,REST server,etc.).
gradle marklogic-rdf4j:mlDeploy

You should be able to test marklogic-rdf4j repository by running:

gradle marklogic-rdf4j:test

Build and Deploy

Build and deploy a local maven marklogic-rdf4j build by running;

gradle marklogic-rdf4j:install

optionally you can build the jar without running tests.

gradle build -x test

and copy resultant marklogic-rdf4j/build/libs/marklogic-rdf4j-1.2.2.jar.
