4.0 out of 5 stars Good material, but not for the stated audience..., September 6, 2004

By	Thomas Duff "Duffbert" (Portland, OR United States) - See all my reviews (TOP 50 REVIEWER)    (REAL NAME)

If you're looking to get an in-depth understanding of open source licensing and all the issues surrounding it, you should read Open Source Licensing by Lawrence Rosen (Prentice Hall).

Chapter list: Freedom and Open Source; Intellectual Property; Distribution of Software; Taxonomy of Licenses; Academic Licenses; Reciprocity and the GPL; The Mozilla Public License (MPL); The Common Public License (CPL); The OSL and the AFL; Choosing an Open Source License; Shared Source, Eventual Source, and Other Licensing Models; Open Source Litigation; Open Standards; The Open Source Paradigm; Appendices; Index

On the positive side, this book will teach you more about licensing than you thought existed. This book deals with all the legal issues that either have arisen or could become a problem as open source continues to make inroads against commercial software. The analysis is detailed as only a lawyer can do it. Another positive aspect of the book is that the author covers how different open source licenses mesh with each other. You may be forced into choosing a certain type of license if you've incorporated software that already uses a license that you're expected to apply to your software. All good stuff.

On the negative side, I don't think the book delivers on its promise to present "a plain-English guide to open source law for developers, managers, users, and lawyers". I see this as a book by a lawyer for lawyers needing to understand software licensing and how open source licensing fits into that. Companies that are building a business model around open source will need this material, but the typical developer and nearly all users will be bored to death as individual words are pulled out and dissected as for potential legal interpretations that could be applied.

I'm inclined to rank this a little higher than I'd like just because there's not a lot of material about this subject, and the author *does* cover it in great detail. But if you think you're going to get an easy-to-digest explanation of open source licensing, you will probably be disappointed.

4.0 out of 5 stars Clarifies licensing issues, August 14, 2004

By	W Boudville (Terra, Sol 3) - See all my reviews (TOP 10 REVIEWER)    (REAL NAME)

At the core of the open source movement are licensing issues. These are still relatively new and potentially confusing to many. Here, Rosen offers a major clarification of the key ideas. He discusses the basic motivation underpinning the most common licenses, like GPL, CPL, OSL and MPL. These are compared with each other and with what might be considered the closest previous type of license - that used in academia. While the final choice is yours, he gives you a solid basis for determining that choice.

For many readers, there will be an interesting analysis of the SCO versus Open Source fracas. In essence, he suggests that after all the dust has settled, it will break no new ground in contract law. Nor will it stymie or halt the open source movement. A relief to many, if his assessment proves true.

5.0 out of 5 stars Great for reference, October 23, 2004

By	Elizabeth Krumbach (Schwenksville, PA United States) - See all my reviews

When I recieved this book I was excited, finally I could read a book which would help my brain really understand all the licenses! I sat down to read it, and was impressed with how the author took the popular licenses and broke them down into more easily understandable. I mean, they *are* fairly straight forward, but the author gets into what they actually mean in legal terms, and that's interesting.

Unfortunately it turns out that reading about specifics of Open Source law is not terribly interesting to me (I guess I'll never be a lawer) After the few introduction chapters I had to stop reading straight through it and skip around and skim the parts that interested me.

In my case this is not such a good book for snuggling up with in front of the fire (some computer books are), but it is a fabulous reference book, written for us mere mortals.
