[UPDATED: To remove my comment about the absence of workflow config in Share, which Martin does cover. Sorry about that, Martin]
Overall, I think it is a good book with a lot of useful information across a variety of topics. The preface says the book is for “systems administrators and business owners”. Inclusion of “business owners” is a stretch–they’d have to be pretty technical to get something out of this book. I think the intent of including “business” in the title and the target audience is to set up the book as more of a solution-oriented look at Alfresco and less of an exhaustive technical how-to.
Bergljung attempts to organize the book around “business solution” focused chapters. For example, if your main concern is letting your users access the repository through file protocols, then Chapter 5, File System Access Solutions, is for you. If you are doing a content migration to Alfresco, Chapter 8, Document Migration Solutions outlines the different approach available for doing that. I think this is a good approach for the stated audience and most of the chapters fit the approach.
The book starts out with an overview of the Alfresco platform and various repository concepts. Although there are places that risk going into too much detail too early, that first chapter would be a good read for anyone new to Alfresco. The chapters on authentication and synchronization (Chapter 4) and CIFS/WebDAV (Chapter 5) are very thorough and provide some of the best coverage of those topics I’ve seen in any of the Alfresco books. The vigor with which Bergljung attacked those topics makes me think those areas are a particular passion for him. If you are strict about the target audience, Chapters 4 & 5 are definitely the strongest in the book.
However, at various points, the book strays from its intended audience and starts to go into developer topics. Don’t get me wrong, that’s the most interesting stuff to me, but I think it is potentially confusing (or, at best, superfluous) to system administrators. For example, the end of Chapter 1 covers the underlying database schema. Maybe it is a good idea to discuss what the tables are and how they are used so that a DBA gets a feel for the schema and can tune the database appropriately. But Alfresco’s schema is not public and shouldn’t be accessed directly unless you know what you’re doing and if you are willing to sign up for the inevitable maintenance down the road when the schema changes without warning. Bergljung gives a soft warning to this effect at the start of the section but the negative effects could have been emphasized more.
Another piece I don’t agree with is about $TOMCAT_SHARED. To be fair, I’ve seen this in other places and have heard certain Alfresco Engineers encouraging the use of $TOMCAT_SHARED for things I think belong in the web app instead. Regardless of where it comes from, I think it’s really bad advice to tell people to use $TOMCAT_SHARED for anything other than alfresco-global.properties and server- or environment-specific settings. Proponents of $TOMCAT_SHARED will say they like deploying their customizations there for two reasons. First, when Alfresco and Share are deployed in the same Tomcat instance, you can deploy your extensions as one package and both web apps will use it. Second, your extensions go into an extension directory external to the Alfresco WAR, which keep them well away from Alfresco’s code. In my option, both of these are actually reasons NOT to use $TOMCAT_SHARED. Why? As to the Alfresco/Share sharing bullet point, why unnecessarily couple those two web apps together? The Alfresco and Share WAR are built to run on completely separate nodes which is helpful. We shouldn’t ruin that by making them both rely on the same shared directory.
As for the “keep your extensions away from Alfresco’s” reason, that’s what the extension directory is for. I can keep my customizations separate and still have them reside in Alfresco’s WAR. In fact, most clients I’ve dealt with prefer that because they have IT Operations teams that only want to deal with self-contained WARs. Being a “special case” is not how you win the hearts and minds of your infrastructure team.
In keeping with the “solutions” approach, I think I would have combined the portlet chapter and the mobile app/Grails chapter into a single “integration solutions” chapter and talked less about the specific implementation details and more about the touch points: options for integration (Web Services, CMIS, custom web scripts), single sign-on approaches, what’s available out-of-the-box, caveats, etc. Most of this is covered one way or another between the two chapters. It just seems like a common thing people think through is “What’s the best approach for doing X on top of Alfresco” where X is a portal like Liferay, a community platform like Drupal, a mobile app, and so on.
So, if you’re a “business owner” and by that you mean “non-technical end-user”, you’d probably be better off with Munwar’s book, which is definitely end-user focused. If you are a “system administrator” or someone who needs to know the capabilities of Alfresco and how to integrate Alfresco with various touch points (LDAP, Active Directory, portals), it’s definitely worth a read, particularly if you need to deal with external authentication sources or you are responsible for getting CIFS working. Developers will benefit from the API examples and the chapters on Alfresco’s embedded jBPM engine.
Congrats to Martin and Packt. It’s good to see another title (I think we’re up to 8 or 9 now) added to the Alfresco bookshelf.
