Using (Installing) Jena in Netbeans

When  I first tried to use Jena in Protégé, I was quite confused... I couldn't compile my code and I wasn't sure if my code was wrong or if hadn't installed the right jars in Netbeans.... So, after searching in the web I 've found this great video (I don't know what language is this... but I managed to understand finally) that explains how to use Jena in Netbeans IDE.

Semantic Web books: Semantic Web Programming

Semantic Web Programming  by John Hebeler, Matthew Fisher, Ryan Blace, Andrew Perez-Lopez, Mike Smith and  Mike Dean was published in 2009. This book introduces semantic web programming with examples in Java. The book uses the Jena framework, Protégé and the Eclipse IDE, I have read some parts of the book and I found it useful but as I decided to leave Jena and start programming with OWL API (I will shortly introduce OWL API) I never finished the book.

Semantic Web Programming provides both hands-on examples and in-depth technical explorations of the technologies and standards of the Semantic Web. The goal of the book is to provide developers with an invaluable resource that can be used initially as a resource for learning and later as an invaluable reference. Below you will find a full listing of the chapters contained in the book, which are divided into four major parts, each building on the previous.

Part One – Introducing Semantic Web Programming


1. Preparing to Program a Semantic Web of Data

2. Hello Semantic Web World

Part Two – Foundations of Semantic Web Programming


3. Modeling Information

4. Incorporating Semantics

5. Modeling Knowledge in the Real World
6. Discovering Information
7. Adding Rules

Part Three – Building Semantic Web Applications


8. Applying a Programming Framework

9. Combining Information

10. Aligning Information
11. Sharing Information

Part Four – Expanding Semantic Web Programming


12. Developing and Using Semantic Services

13. Managing Space and Time

14. Semantic Web Patterns and Best Practices
15. Moving Forward

Appendices

Appendix A – RDF

Appendix B – The OWL Web Ontology Language

Appendix C – SWRL
Appendix D – SPARQL
Appendix E – Jena Reference Guide
Appendix F – Installation Reference Guide

Jena - a semantic web framework

Hello! Today I will introduce Jena - a framework for building semantic web applications.


From the official site of Jena:
Jena is a Java framework for building Semantic Web applications. It provides a programmatic environment for RDF, RDFS and OWL, SPARQL and includes a rule-based inference engine.
Jena is open source and grown out of work with the HP Labs Semantic Web Programme.
The Jena Framework includes:
  • A RDF API
  • Reading and writing RDF in RDF/XML, N3 and N-Triples
  • An OWL API
  • In-memory and persistent storage
  • SPARQL query engine
Besides, Jena's documentation in sourceforge I found very useful this article by IBM for an introduction on how Jena works.
Another useful link, is this youtube video, which gives detailed instructions on using Jena in Netbeans. I don't know what language is this, but I understood what to do. :)

Cheers,
Angeliki
