"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

"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.

"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!)."

- Priscilla Walmsley, author of O'Reilly's "XQuery"

"A full introduction to SPARQL is out of the scope of this book. For the interested reader, we recommend 'Learning SPARQL'."

- Jose Emilio labra Gayo, Eric Prud'hommeaux, Iovka Boneva, Dimitris Kontokostas, Validating RDF

" In case you seriously want to use SPARQL, then buy the book 'Learning SPARQL' 2nd edition"

- Hans Teijgeler

"Highly recommended for anybody consuming GoodRelations data."

- Martin Hepp

"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."

- Dave McComb, Semantic Arts

"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."

- Edd Dumbill

"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."

- "Free Your Data" blog

"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."

- Shawn Day

"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."

- David Witherspoon

"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

"For a good introduction to SPARQL, I recommend Bob DuCharme's Learning SPARQL."

- Steve Baskau in SPARQL: the weirdness of unnamed graphs

What are the good books for learning SPARQL beyond @LearningSPARQL? 20 Jun

@rhizome Incredible feeling to have our ArtBase work used as an example by the author of Learning SPARQL himself 🥰* 23 May

@linkedktk I did read Working Ontologist which has a great intro but most I learned from @LearningSPARQL. I think it's important to get hands dirty fast and make sure what you model can be queried easily. If this is not the case you probably overengineered for your use case 27 Apr

@kushaldas Oh, just in case you want to learn SPARQL, the book @LearningSPARQL is the best resource I found :) 10 Feb

@epos http://learningsparql.com I bought the dead-tree version of this to read at leisure when away from the computer. @LearningSPARQL

It now also lies on my desk as a reference. 30 Jan 2022

@modelreduction #SPARQL is super powerful, and the book "Learning SPARQL": oreilly.com/library/
by @bobdc via @OReillyMedia is an awesome resource covering many aspects of RDF querying. See also @LearningSPARQL 8 Dec

@RacNets The best way to learn RDF, SPARQL and LinkedData: Just do it. I'm building my first ontology and triple store for courses @MPI_EvolBio from scratch and heaving prepared with the excellent @LearningSPARQL by @bobdc: Hurray, it works! 22 Sep

@heald_j Does the BM still offer a SPARQL service ?
Might be useful, now the collection webpages use the same IDs.
(And yes, @bobdc 's book is excellent) 8 Jun

@NicoMatentzoglu Just re-read @LearningSPARQL despite working with the language for years and still got so much from it, again! Reading textbooks after years of practice is so useful, can’t stress this enough.22 May 2021

@Aquacold1 .@LearningSPARQL by @bobdc was my go-to SPARQL reference guide when developing the @Aquacold1 linked data question answering prototype for my studies. An excellent guide to the language. 11 Dec

@andrecastro0o Where would I be without @LearningSPARQL ? Such a great guide! Could not recommend it more to those wanting to learn but #rdf #sparql #semanticweb 14 Nov

@Carlos_F_Enguix An Excellent down-to-earth intro to the SPARQL Protocol and RDF Query Language or SPARQL. Bob DuCharme’s book is a must-have for those interested in the Semantic Web. 27 Mar

@CharlesMatthe12 Can't agree that the @wikidata query service is hard to learn. I learned SPARQL from it (assisted by Bob's book); I have trained others from it. It takes a couple of hours to get started: in line with wiki thinking, there is a quick way in. 3 Feb 2020

@namedgraph Definitely get the @LearningSPARQL book :) I think he also would recommend this video: https://youtube.com/
As for the HTTP protocol, the standard can be found here: https://w3.org/TR/
23 Sep

@tmtn The single most perfect resource out there for SPARQL is @bobdc's @LearningSPARQL. Get your hands on that book. I have a hardcopy, with tear-soaked, dog-eared, annotated, highlighted pages and I have never been willing to lend my copy to anyone 17 Aug

@tmtn Yes the ProgrammingHistorian one, and buy the @LearningSPARQL book by @bobdc - it's *amazing* 24 Jul 2019

@5555thats5fives this RDFS/OWL book feels dense... simple concepts are made difficult through unnecessary formality and "clarifications" borne not of the confusions that a fresh student might have but past technical debates between insiders. the o'reilly SPARQL book was way more straightforward 1 Aug

@KeithWheeles/ What I'm reading... https://www.amazon. com/Learning-SPARQL... 05 Mar

@tmtn cool. Fuseki is the one @bobdc uses in his amazing #SPARQL book (as I'm sure you already know). I love that book. 13 Feb

@novastaylor A great way to learn #RDF is with the @LearningSPARQL book by @bobdc. By learning how to query RDF with #SPARQL, you learn how it is all put together. Excellent book. 25 Jan 2018

@dominicbordelon i'm not really SPARQL-conversant, maybe one day i will be, but i like the "learning SPARQL" book by o'reilly 19 Jul

@vmdbks I'm repeating what others have said, but I recommend the @ProgHist tutorial and the @LearningSPARQL book. 19 Jul

@cm_harlow semantic web for the working on ontologist has a decent chapter on it. the o'reilly learning sparql book has gotten praise from colleagues 19 Jul

@garner @psd My bible was Learning SPARQL — that looks a bit more general, thanks. Given what I'm doing next week I should install Fuseki, though 4 Apr

@pumba_lt @ruthbrarian #RDF is not syntax, it's a data model - serializations are the syntax. I also recommend the @LearningSPARQL book. 22 Mar

Learning SPARQL cover

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.
