"I buy it and give it away at every course I teach on the semantic web. It is a well-written and entirely practical way into this world. You can explore a significant portion of the concepts without having to set anything up. I have seen no better way to get started."
- Brian Sletten, Bosatsu Consulting and author of Resource-Oriented Architecture Patterns for Webs of Data
"It's excellent—very well organized and written, a completely painless read. I not only feel like I understand SPARQL now, but I have a much better idea why RDF is useful (I was a little skeptical before!)."
"You really did a great job. Not only does your book explain SPARQL well but also all the 'semantic web stuff' around it. I'm using it right now at a customer site."
- Jans Aasman, President and CEO, Franz Inc.
"Highly recommended for anybody consuming GoodRelations data."
"It's a really a great book. I feel like I GET it. It's not only improved my understanding of SPARQL but also of RDF's possibilities."
- Ruth Kitchin Tillman, Metadata Librarian at NASA Goddard
"Well organized, progresses well and has great examples."
"With SPARQL, the semantic web has its SQL, and is definitely the richer for it. And with the publication of Bob's book, all the more so."
"It is an excellent text. I keep a copy on my desk and use it regularly!"
- Susannah Barnes, Metadata Analyst
"An excellent introduction for those who want to start using this powerful tool."
"It comprehensively leads one through the why and wherefore of SPARQL and provides a thorough grounding in the vocabulary and practice of employing SPARQL to start to benefit from the growing world of Linked Data."
"I had always know that SPARQL would be similar to SQL due to the fact that they are both query languages, but I did not realize how powerful SPARQL queries could be and all the great functions that are provided in the language until reading Bob DuCharme book Learning SPARQL."
"This is a good book for developers who know how to program, ideally know SQL, and who want to find out about SPARQL. It has plenty of well-constructed examples, and should get you well on the way to being able to use SPARQL in your apps."
- Kay Ewbank in I Programmer
recent tweets about "Learning SPARQL:
The W3C standard query language SPARQL is letting people access a growing collection of public and private data. Whether this data is part of a semantic web project or a combination of data from two relational databases on different platforms, SPARQL is making it easier to access this data using both open source and commercial software. "Learning SPARQL" teaches you how to use SPARQL 1.1 by starting you off with simple queries that demonstrate the language's query-by-example approach and then taking you through all the key features of the SPARQL 1.1 query and update languages. All example code is provided for you to run yourself with free software, and the book's table of contents and detailed index lets you use it as a reference book long after you've finished working through its examples.
