Maven-based ontology development and management of ontology artifacts in distributed ontology repositories.

###User Guide (April 2016)

This document is for end users who are looking for information on how to run and use OntoMaven.

Prerequirements

In order to run OntoMaven on your machine, you need:

  • Mandatory is a Java Virtual Machine (JVM). Java 8 for 64-bit systems tested and found to be as a stable JVM for OntoMaven. Depending on your use case you may want to assign more RAM than assigned as default.
  • An up-to-date Apache Maven version. At the time of creation of the guide at least Maven 3.0.5 was verified as a running version.
  • If you want to use OntoMaven as a Maven project inside Eclipse or some other IDE you need their relevant Maven plugins. Please consider to use corresponding manuals for installation and usage.
  • For support of distributed repositories you need to install a source code management (SCM) system like Git or Subversion (SVN).
Installation and configuration details

Before you start to use the instructions from this section, be sure you already fulfilled the prerequirements mentioned in the section before.

Since OntoMaven is an open source project, you can get the source code and build it on your own. You can retrieve the source code of OntoMaven on the project's site http://www.corporate-semantic-web.de/ontomaven.html.

You can build and deploy OntoMaven like usual for a Maven based application with the command mvn build on the command line or the corresponding command in your favorite IDE.

In order to start the application to import ontologies and to collaborate with other knowledge engineers and domain experts, your command should have the following form (parameters are optional):

mvn de.csw:ontomaven:<goal_name> [-D<parameter_name>=<parameter_value>]

In Eclipse or other similar IDE you can start goals from the given configuration menu to run applications. Here you should insert de.csw:ontomaven:<goal_name> into the menu field to define your goal.

The available goals and their parameters are listed in another section.

By default the support for distributed repositories is not active. Edit the pom.xml file in the root directory of OntoMaven to specify your ontology repository.

The following code snippet shows you how to connect with some repository server using SVN:

<project>
...
<scm>
	<connection>scm:svn:http://somerepository.com/svn_repo/trunk</connection>
	<developerConnection>scm:svn:https://somerepository.com/svn_repo/trunk</developerConnection>
	<url>http://somerepository.com/view.cvs</url>
</scm>
...
</project>

Instead of SVN you can connect to any other supported SCM.

Supported SCM

As of this writing the following SCMs are fully supported:

  • Bazaar
  • CVS
  • Git
  • Mercurial
  • Subversion
  • ...

Goals: Function and parameters
  • ApplyAspects

    Applys the choosen aspects of the ontology and creates a new result ontology.

    • owlDirectory with default value "owl"
    • owlFileName with default value "ontology.owl"
    • aspectsIRI with default value "http://www.corporate-semantic-web.de/ontologies/aspect_owl#hasAspect"

    <aspect>myFirstAspect</aspect>
    <aspect>mySecondAspect</aspect>
    ...
</userAspects>
  • CreateOntologyGraph

    Creates a graphml file of the ontology. The result file can be visualized by any tool supporting graphml files. Included into OntoMaven is also

    • owlDirectory with default value "owl"
    • owlFileName with default value "ontology.owl"
    • aspectsIRI with default value "http://www.corporate-semantic-web.de/ontologies/aspect_owl#hasAspect"
    • ifApplyAspects with default value false
    • userAspects defined at the pom.xml file in the root directory of OntoMaven with the following lines:
     <userAspects>
     <aspect>myFirstAspect</aspect>
     <aspect>mySecondAspect</aspect>
     ...

  • CreateOntologyReport

    Generates a report for the ontology. This report will contain information about the ontology and its elements like classes, properties, individuals.

    • ontologyReportOutputDirectory with default value "target/site/ontologyReport"
