Federated Infrastructures Ontology

Abstract

This repository contains the work conducted in the W3C Federated Infrastructures Community Group. It includes a formal information model for federated infrastructures (omn) and a Java library (omnlib) to translate between our Open-Multinet Ontology, GENI v3 RSpecs (plus extensions), OASIS TOSCA, and the IETF NFV models.

Java omnlib

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

Using it

CLI

mvn compile
cd omnlib
./src/main/bin/omnlib -o ttl -i ./src/test/resources/geni/request/request_bound.xml

Web Service

Assuming you have a running WildFly instance

 cd omnweb
 mvn clean install
 mvn wildfly:deploy

Then convert the file

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

Developing it

Using it in your own project

Add this repository to your pom.xml file:

    </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
