A new edition of this book just came out.<div><br></div><div><div><b>Semantic Web for the Working Ontologist, Second Edition: Effective Modeling in RDFS and OWL</b> [Paperback]</div><div>Dean Allemang, James Hendler</div></div>
<div><br></div><div><a href="http://www.amazon.com/Semantic-Web-Working-Ontologist-Second/dp/0123859654/">http://www.amazon.com/Semantic-Web-Working-Ontologist-Second/dp/0123859654/</a><br clear="all"><br>Starting on page 326 there is a good section on OWL subsets and Modeling Philosophy.</div>
<div><br></div><div>It describes provable models (decidable) and executable models.</div><meta charset="utf-8"><div><br></div><div>There is a lot of good info in here, but I thought I would highlight these sentences.</div>
<div><br></div><div><i>&quot;In fact, it is quite challenging to come up with a logical system that can represent anything useful that is also decidable&quot;  </i></div><div><br></div><div>also under Executable Models.</div>
<div><br></div><div><i>&quot;A different motivation for modeling in the Semantic Web is to form an integrated picture of some sort of domain by federating information from multiple sources&quot;</i></div><div><br></div><div>
Individuals should really read the entire chapter and come to their own conclusions, but I think these are issues that people need to think about.</div><div><br></div><div>To what extent can we design a system that actually is decidable?</div>
<div><br></div><div>How are these models going to be used, what is their purpose, and what are some clear use cases?</div><div><br></div><div>Here is the use case that started me down path of linked data and the semantic web.</div>
<div><br></div><div>I am in location X,Y and have a specimen of family Z.</div><div><br></div><div>What species of family Z are expected here and what are the characters that can be used to differentiate them?</div><div><br>
</div><div>Give me a list of other resources that contain information about these species.</div><div><br></div><div>Respectfully,</div><div><br></div><div>- Pete</div><div><br>
