This book is currently (March 2010) a work in progress and will be released around June 2010 as a print book (Lulu.com), a paid for PDF file (Lulu.com), and a free (identical) PDF file.

You can get the free PDF on my Open Content web page www.markwatson.com/opencontent/. A partially complete (about 130 pages) PDF is now available.

All of the book software examples that I wrote are licensed using the AGPL license. Additionally, if you purchase either the PDF or print book then you can, if you want to do so, use the book example software under the terms of the license in the file commerciallicense.txt

I use a variety of 3rd party JAR files contained in the lib directory.

While most of the software is written in Java, I have made an attempt to also support people who prefer JRuby, Clojure, or Scala with wrappers for those languages.

I have written compatibility wrappers so the book examples can use either the open source Sesame RDF repository or the commercial AllegroGraph product. My wrapper for Sesame adds support for geolocation and text indexing and search.

Hopefully the book example programs will be stable and ready for general use by May 2010.

I use IntelliJ for development for Java, Scala, and Clojure. When the book examples are complete I will add an ant build.xml file to build and run the examples.
