Semantics offer quite a bit to the evolving stack of SOA services.  Our talked outlined four increasingly powerful semantic additions to aiding SOA goals.  Here is the presentation and here is the code [zip|7z|tar.gz] for the Apache Synapse SPARQL mediator if you want to further explore on your own.  Please send any suggestions and ideas to further semantics in SOA.

We’ve released an update to the FriendTracker application that accompanies the book. The updated code can be found on the downloads section of the web site, or the following links [zip|7z|tar.gz]. This is the code that we (John Hebeler and Ryan Blace) demonstrated at the DC Semantic Web meetup in August (sorry to those who were waiting for me to post the code… my daughter was born the day after the meetup!)

Updates:
- Sorted names in the names list
- Improved status reporting
- Lots of bug fixes
- Ported to Pellet 2.0 for large performance improvement
- Improved error reporting

This is the second article in our series that expands the code example from Chapter 5 of Semantic Web Programming to cover the semantics of OWL 2. This article covers property chains. The code can be downloaded from here (zip, 7z, tar.gz) and includes an Eclipse project with all required dependencies.

This article focuses on the semantics of property chains and how they are interpreted and applied in a reasoner that supports most of OWL 2 semantics (Pellet 2.0 RC6 – see the Pellet documentation for a full list of the semantics supported in each release candidate).

As I said in the first article, for a more in-depth exploration of OWL and Semantic Web, feel free to reference the book as needed or buy a copy so you can learn about the cool stuff in this article and more. Click the link below to read the rest of the article…

This article is the first in a short series of articles that expands the code example from Chapter 5 of Semantic Web Programming to include some of the features of OWL 2. The code can be downloaded from here (zip, 7z, tar.gz), including an Eclipse project and all dependencies. This article focuses on how the semantics of qualified cardinality restrictions are interpreted and applied in a reasoner that supports most of OWL 2 semantics (Pellet 2.0 RC6 – see the Pellet documentation for a full list of the semantics supported in each release candidate).

Recall from Chapter 4 in the book that cardinality restrictions are a way to specify the number of statements that describe an individual with a unique value that have a particular property as the predicate of each statement… Read more…
