Semantic Web Programming

Hey Ryan (and company). Just wanted to say congrats on the release of your book. I’m actually reading through my copy right now and I think it’s going to be a pretty valuable resource on a project I’m working on. Hope things are going well for you guys!

Is there a digital (eg PDF) version of this book available?

Is the book available in a digital (eg PDF) version?

I asked this before and my comment was deleted. Note that I’m not requesting links to a pirated version of the book, but rather the ability to buy an electronic version. I haven’t bought a paper book on any technical subject for years.

Unfortunately, no. We (the authors) agree it would be great if it would happen, but such things are at the discretion of the publisher (Wiley). I’m not sure what is involved in their decision process, but you might email them about it to put it on their radar. As a consolation, you can download Chapter 10 in its entirety in PDF at http://semanticuniverse.com/. We had a cross-promotion deal with them. Chapter 10 is one of the longer chapters as it is (~60 pages).

Sorry we can’t help more, but thanks for the interest.

Hi guys. Your book seems to be very comprehensive. However, I find that it skips a lot of steps in explaining how to run the Jena API code samples and what output can the user expect.

Hi, I’m working my way through the book, and would like to know where I could find the implemention of the ‘applySelfRule’ method of the ‘HelloSemanticWeb’ class discussed in chapter 2.

Question : is the namespace address correct?

I tried both
http://org.semwebprogramming/chapter2/people# (from the downloaded chapter2)

and http://semwebprogramming.org/2009/ont/chp2:# (from the book).

Neither is working.

The problem isn’t with the uri. You are missing the local file. It is a misleading error message. I regret not putting ANY error checking code to keep it simple. Let me know if that helps. J Hebeler

@jhebeler
I believe that at least one of the two URI is not correct. I replaced the namespace uri with a different one referring a rdf file created by me. The execution went further but it stopped at the line
_friends.read(inFoafInstance,defaultNameSpace);
with the msg error
“White spaces are required between publicId and systemId”.
