Open-Multinet Ontology Playground

Abstract

Java library (omnlib) and playground for the ontology work conducted in the Open-Multinet context. The goal is to offer a converter between GENI v3 RSpecs and selected extensions, the Open-Multinet Ontology, and OASIS TOSCA.

Ontology

• Upper Ontology (omn)
• Further information
• GENI RSpec Description
• GENI RSpec Examples

Java omnlib

The Java library helps developers to work wiht Open-Multinet related ontologies and includes a translator to convert between RDF, GENI RSpec XMLs, and TOSCA XML.

Using it

CLI

./src/main/bin/omnlib -o ttl -i src/test/resources/request_bound.xml

Web Service

Assuming you have a running WildFly instance

1. mvn clean compile
2. mvn wildfly:deploy

Then convert the file

curl --data-urlencode content@src/test/resources/geni/request/request_bound.xml http://127.0.0.1:8080/omnlib/convert/request/ttl

Developing it

Using it in your own project

Add this repository to your pom.xml file:

<project>
  ...
  <repositories>
    <repository>
      <id>sonatype</id>
      <url>https://oss.sonatype.org/content/groups/public/</url>
    </repository>
  </repositories>
  ...
  <dependencies>
    <dependency>
      <groupId>info.open-multinet</groupId>
      <artifactId>omnlib</artifactId>
      <version>0.0.1-SNAPSHOT</version>
    </dependency>
  </dependencies>
  ...
</project>

Enhancing the library

1. Checkout the code
2. Run "mvn clean compile" to auto generate binding files
3. Open with IDE (e.g. Eclipse or IntelliJ)

Directory Layout

• bin: executables
• data: example data to work with (to help validating and discussing the ontologies)
• generated: auto generated files based (e.g. documentation, graphical representation, other serializations)
• import: related ontologies to be reused (second main focus)
• ontologies: upper ontologies (to main focus)
• queries: example queries to work with (to help validating and discussing the ontologies)
• src: omnlib (Java implementation and tests)

Suggested Tools

• sparql (command line tool from jena to query data)
• Protégé (graphical ontology editor)
• Eclipse Xturtle (text based ontology editor with code completion and simple validation)
• rdf.sh (command line ontology tools)
• OwlToUml (to visualize simple ontologies as plantuml diagrams)
• rapper (command line tool to convert and check ontologies)
• lodlive (user friendly vizualization of a sparql endpoint)
• yasgui (user friendly query of a sparql endpoint)
• LODE (documentation generator for OWL files)

How To (rather old approach)

Run example Queries

./bin/runQuery.sh

Example (pre defined): Get the published nodes

./bin/runQuery.sh example2

Example (arbitrary): Get the status of the nodes for FLS

./bin/runQuery.sh advertisement-fp getnodestatus
