Why SPARQL?

SPARQL is the query language of the Semantic Web. It lets us:

Pull values from structured and semi-structured data
Explore data by querying unknown relationships
Perform complex joins of disparate databases in a single, simple query
Transform RDF data from one vocabulary to another

Assumptions

RDF is a data model of graphs of subject, predicate, object triples.
Resources are represented with URIs, which can be abbreviated as prefixed names
Objects can be literals: strings, integers, booleans, etc.
Turtle: a bit of syntax
- URIs: <http://example.com/resource> or prefix:name
- Literals: "plain string" "13.4"^^xsd:float or "string with language"@en
- Triple: pref:subject other:predicate "object" .
- More shortcuts & abbreviations as we go.

Structure of a SPARQL Query

A SPARQL query comprises, in order:

Prefix declarations, for abbreviating URIs
Dataset definition, stating what RDF graph(s) are being queried
A result clause, identifying what information to return from the query
The query pattern, specifying what to query for in the underlying dataset
Query modifiers, slicing, ordering, and otherwise rearranging query results

# prefix declarations
PREFIX foo: <http://example.com/resources/>
...
# dataset definition
FROM ...
# result clause
SELECT ...
# query pattern
WHERE {
    ...
}
# query modifiers
ORDER BY ...

SPARQL Architecture & Endpoints

SPARQL queries are executed against RDF datasets, consisting of RDF graphs. (More on this later.)
A SPARQL endpoint accepts queries and returns results via HTTP.
- Generic endpoints will query any Web-accessible RDF data
- Specific endpoints are hardwired to query against particular datasets
The results of SPARQL queries can be returned and/or rendered in a variety of formats:
- XML. SPARQL specifies an XML vocabulary for returning tables of results.
- JSON. A JSON "port" of the XML vocabulary, particularly useful for Web applications.
- RDF. Certain SPARQL result clauses trigger RDF responses, which in turn can be serialized in a number of ways (RDF/XML, N-Triples, Turtle, etc.)
- HTML. When using an interactive form to work with SPARQL queries. Often implemented by applying an XSL transform to XML results.

SPARQL 1.1 is in-progress, and includes:

Updated 1.1 versions of SPARQL Query and SPARQL Protocol
SPARQL 1.1 Update
SPARQL 1.1 Graph Store HTTP Protocol
SPARQL 1.1 Service Descriptions
SPARQL 1.1 Entailments
SPARQL 1.1 Basic Federated Query

Dataset: Friend of a Friend (FOAF)

FOAF is a standard RDF vocabulary for describing people and relationships
Tim Berners-Lee's FOAF information available at http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf
For our first query, let's find all the names of people mentioned in Tim's FOAF file:

@prefix card: <http://www.w3.org/People/Berners-Lee/card#> .
@prefix foaf:  <http://xmlns.com/foaf/0.1/> .

card:i foaf:name "Timothy Berners-Lee" .
<http://bblfish.net/people/henry/card#me> foaf:name "Henry Story" .
<http://www.cambridgesemantics.com/people/about/lee> foaf:name "Lee Feigenbaum" .
card:amy foaf:name "Amy van der Hiel" .

...

Query #1: SELECT, variables, and a triple pattern

In the graph http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf, find me all subjects (?person) and objects (?name) linked with the foaf:name predicate. Then return all the values of ?name. In other words, find all names mentioned in Tim Berners-Lee's FOAF file.

PREFIX foaf:  <http://xmlns.com/foaf/0.1/>
SELECT ?name
WHERE {
    ?person foaf:name ?name .
}

SPARQL variables start with a ? and can match any node (resource or literal) in the RDF dataset.
Triple patterns are just like triples, except that any of the parts of a triple can be replaced with a variable.
The SELECT result clause returns a table of variables and values that satisfy the query.
Dataset: http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf

Running Our First Query

This query is against an arbitrary bit of RDF data (Tim Berners-Lee's FOAF file). So we need a generic endpoint to run it. We can choose from:
- OpenJena's ARQ at sparql.org
- OpenLink's Virtuoso (Make sure to choose "Retrieve remote RDF data for all missing source graphs")
- Redland's Rasqal.
Each endpoint provides a form for us to input the query and the data graph. Results are returned as an HTML table.
Dataset: http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf

PREFIX foaf:  <http://xmlns.com/foaf/0.1/>
SELECT ?name
WHERE {
    ?person foaf:name ?name .
}

Try it yourself! (Expected results.)

Exercise #1: Give me all the properties about Apollo 7

Given:

Talis endpoint <http://api.talis.com/stores/space/services/sparql>.
Apollo 7 known as <http://nasa.dataincubator.org/spacecraft/1968-089A>.

Solution #1: Give me all the properties about Apollo 7

SELECT ?p ?o
{ 
  <http://nasa.dataincubator.org/spacecraft/1968-089A> ?p ?o
}

(query)

Query #2: Multiple triple patterns: property retrieval

Find me all the people in Tim Berners-Lee's FOAF file that have names and email addresses. Return each person's URI, name, and email address.

PREFIX foaf:  <http://xmlns.com/foaf/0.1/>
SELECT *
WHERE {
    ?person foaf:name ?name .
    ?person foaf:mbox ?email .
}

We can use multiple triple patterns to retrieve multiple properties about a particular resource
Shortcut: SELECT * selects all variables mentioned in the query
Dataset: http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf

Try it with ARQ, OpenLink's Virtuoso, or Redland's Rasqal. (Expected results.)

Exercise #2: URLs for Apollo 7

What URL does this database use for Apollo 7?
What is the (NASA) homepage for the mission?

Given the Talis endpoint:

uses foaf for names and homepages.
namespace for foaf is <http://xmlns.com/foaf/0.1/>

Solution #2: URLs for Apollo 7

PREFIX foaf: <http://xmlns.com/foaf/0.1/>
SELECT ?craft ?homepage
{
  ?craft foaf:name "Apollo 7" .
  ?craft foaf:homepage ?homepage
}

(query)

Query #3: Multiple triple patterns: traversing a graph

Find me the homepage of anyone known by Tim Berners-Lee.

PREFIX foaf:  <http://xmlns.com/foaf/0.1/>
PREFIX card: <http://www.w3.org/People/Berners-Lee/card#>
SELECT ?homepage
FROM <http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf>
WHERE {
    card:i foaf:knows ?known .
    ?known foaf:homepage ?homepage .
}

The FROM keyword lets us specify the target graph in the query itself.
By using ?known as an object of one triple and the subject of another, we traverse multiple links in the graph.

Try it with ARQ, OpenLink's Virtuoso, or Redland's Rasqal. (Expected results.)

Exercise #3: What was the point of Apollo 7?

Given, the Talis endpoint:

Apollo 7 known as <http://nasa.dataincubator.org/spacecraft/1968-089A>.
associates missions with space:discipline.
labels things with rdfs:label.

Solution #3: What was the point of Apollo 7?

PREFIX space: <http://purl.org/net/schemas/space/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT ?disc ?label
{
  <http://nasa.dataincubator.org/spacecraft/1968-089A> space:discipline ?disc .
  ?disc rdfs:label ?label
}

(query)

Dataset: DBPedia

DBPedia is an RDF version of information from Wikipedia.
DBPedia contains data derived from Wikipedia's infoboxes, category hierarchy, article abstracts, and various external links.
DBpedia contains over 100 million triples.

Query #4: Exploring DBPedia

Find me 50 example concepts in the DBPedia dataset.

SELECT DISTINCT ?concept
WHERE {
    ?s a ?concept .
} LIMIT 50

LIMIT is a solution modifier that limits the number of rows returned from a query. SPARQL has two other solution modifiers:
- ORDER BY for sorting query solutions on the value of one or more variables
- OFFSET, used in conjunction with LIMIT and ORDER BY to take a slice of a sorted solution set (e.g. for paging)
The SPARQL keyword a is a shortcut for the common predicate rdf:type, giving the class of a resource.
The DISTINCT modifier eliminates duplicate rows from the query results.

Try it with a DBPedia-specific SPARQL endpoint. (Expected results.)

Exercise #4: Find 50 Spacecraft

Given:

namespace for space <http://purl.org/net/schemas/space/>
spacecraft are called space:Spacecraft

Solution #4: Find 50 Spacecraft

PREFIX space: <http://purl.org/net/schemas/space/>
SELECT ?craft
{
  ?craft a space:Spacecraft
}
LIMIT 50

(query)

Query #5: Basic SPARQL filters

Find me all landlocked countries with a population greater than 15 million.

PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>        
PREFIX type: <http://dbpedia.org/class/yago/>
PREFIX prop: <http://dbpedia.org/property/>
SELECT ?country_name ?population
WHERE {
    ?country a type:LandlockedCountries ;
             rdfs:label ?country_name ;
             prop:populationEstimate ?population .
    FILTER (?population > 15000000) .
}

FILTER constraints use boolean conditions to filter out unwanted query results.
Shortcut: a semicolon (;) can be used to separate two triple patterns that share the same subject. (?country is the shared subject above.)
rdfs:label is a common predicate for giving a human-friendly label to a resource.
Note all the translated duplicates in the results. How can we deal with that?

Try it with one of DBPedia's SPARQL endpoint. (Expected results.)

Exercise #5: Find launches in October 1968

Given, the Talis endpoint:

namespace for space <http://purl.org/net/schemas/space/>
the range of space:launched is xse:date
uses xse:date to say when a craft was launched.
namespace for xsd is <http://www.w3.org/2001/XMLSchema>

Solution #5: Find launches in October 1968

PREFIX space: <http://purl.org/net/schemas/space/>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
SELECT *
{ ?launch space:launched ?date
  FILTER (
    ?date > "1968-10-1"^^xsd:date &&
    ?date < "1968-10-30"^^xsd:date
  )
}

(query)

SPARQL built-in filter functions

Logical: !, &&, ||
Math: +, -, *, /
Comparison: =, !=, >, <, ...
SPARQL tests: isURI, isBlank, isLiteral, bound
SPARQL accessors: str, lang, datatype
Other: sameTerm, langMatches, regex
Conditionals (SPARQL 1.1): IF, COALESCE
Constructors (SPARQL 1.1): URI, BNODE, STRDT, STRLANG
Strings (SPARQL 1.1): STRLEN, SUBSTR, UCASE, LCASE, STRSTARTS, STRENDS, CONTAINS, CONCAT, ENCODE_FOR_URI
More math (SPARQL 1.1): abs, round, ceil, floor, RAND
Date/time (SPARQL 1.1): now, year, month, day, hours, minutes, seconds, timezone
Hashing (SPARQL 1.1): MD5, SHA1, SHA224, SHA256, SHA384, SHA512

Query #6: Filters for picking among translations

Find me all landlocked countries with a population greater than 15 million (revisited), with the highest population country first.

PREFIX type: <http://dbpedia.org/class/yago/>
PREFIX prop: <http://dbpedia.org/property/>
SELECT ?country_name ?population
WHERE {
    ?country a type:LandlockedCountries ;
             rdfs:label ?country_name ;
             prop:populationEstimate ?population .
    FILTER (?population > 15000000 && langMatches(lang(?country_name), "EN")) .
} ORDER BY DESC(?population)

lang extracts a literal's language tag, if any
langMatches matches a language tag against a language range

Try it with a DBPedia-specific SPARQL endpoint. (Expected results.)

Dataset: Jamendo

Jamendo is a community collection of music all freely licensed under Creative Commons licenses.
DBTune.org hosts a queryable RDF version of information about Jamendo's music collection.
Hosts data on thousands of artists, tens of thousands of albums, and nearly 100,000 tracks.

Query #7a: Finding artists' info - the wrong way

Find all Jamendo artists along with their image, home page, and the location they're near.

PREFIX mo: <http://purl.org/ontology/mo/>
PREFIX foaf:  <http://xmlns.com/foaf/0.1/>
SELECT ?name ?img ?hp ?loc
WHERE {
  ?a a mo:MusicArtist ;
     foaf:name ?name ;
     foaf:img ?img ;
     foaf:homepage ?hp ;
     foaf:based_near ?loc .
}

Jamendo has information on about 3,500 artists.
Trying the query, though, we only get 2,667 results. What's wrong?

Try it with DBTune.org's Jamendo-specific SPARQL endpoint. Be sure to choose SPARQL rather than SeRQL. (Expected results.)

Query #7b: Finding artists' info - the right way

Find all Jamendo artists along with their image, home page, and the location they're near, if any.

PREFIX mo: <http://purl.org/ontology/mo/>
PREFIX foaf:  <http://xmlns.com/foaf/0.1/>
SELECT ?name ?img ?hp ?loc
WHERE {
  ?a a mo:MusicArtist ;
     foaf:name ?name .
  OPTIONAL { ?a foaf:img ?img }
  OPTIONAL { ?a foaf:homepage ?hp }
  OPTIONAL { ?a foaf:based_near ?loc }
}

Not every artist has an image, homepage, or location!
OPTIONAL tries to match a graph pattern, but doesn't fail the whole query if the optional match fails.
If an OPTIONAL pattern fails to match for a particular solution, any variables in that pattern remain unbound (no value) for that solution.

Try it with DBTune.org's Jamendo-specific SPARQL endpoint. Be sure to choose SPARQL rather than SeRQL. (Expected results.)

Dataset: HCLS Knowledge Base at DERI Galway

Over 404 million triples
Largest chunk: mirror of the "Neurocommons Knowledge Base" created by Science Commons
Additional datasets added in recent year by members of the W3C Health Care and Life Science Interest Group
Wide range of data: biomedical publications, molecular biology, neuroscience, pharmacology, clinical trials of new drugs, and more

Query #8: Querying alternatives

Find me the cellular processes that are either integral to or a refinement of signal transduction.

PREFIX go: <http://purl.org/obo/owl/GO#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX obo: <http://www.obofoundry.org/ro/ro.owl#>
SELECT DISTINCT ?label ?process
WHERE {
  { ?process obo:part_of go:GO_0007165 } # integral to
      UNION
  { ?process rdfs:subClassOf go:GO_0007165 } # refinement of
  ?process rdfs:label ?label
}

The UNION keyword forms a disjunction of two graph patterns. Solutions to both sides of the UNION are included in the results.
The URI go:GO_0007165 is the identifier for signal transduction in the Gene Ontology
N.B. Cell-surface-receptor-linked signal transduction is a refinement (subclass) of signal transduction

Try it with the neurocommons SPARQL endpoint. (Expected results.)

RDF Datasets

We said earlier that SPARQL queries are executed against RDF datasets, consisting of RDF graphs.
So far, all of our queries have been against a single graph. In SPARQL, this is known as the default graph.
RDF datasets are composed of the default graph and zero or more named graphs, identified by a URI.
Named graphs can be specified with one or more FROM NAMED clauses, or they can be hardwired into a particular SPARQL endpoint.
The SPARQL GRAPH keyword allows portions of a query to match against the named graphs in the RDF dataset. Anything outside a GRAPH clause matches against the default graph.

RDF Datasets

image of multiple interacting RDF graphs

Dataset: semanticweb.org

data.semanticweb.org hosts RDF data regarding workshops, schedules, and presenters for the International Semantic Web (ISWC) and European Semantic Web Conference (ESWC) series of events.
Presents data via FOAF, SWRC, and iCal ontologies.
The data for each individual ISWC or ESWC event is stored in its own named graph; that is, there is one named graph per conference event contained in this dataset.

Query #9: Querying named graphs

Find me people who have been involved with at least three ISWC or ESWC conference events.

SELECT DISTINCT ?name
WHERE {
    ?person foaf:name ?name .
    GRAPH ?g1 { ?person a foaf:Person }
    GRAPH ?g2 { ?person a foaf:Person }
    GRAPH ?g3 { ?person a foaf:Person }
    FILTER(?g1 != ?g2 && ?g1 != ?g3 && ?g2 != ?g3) .
}

The GRAPH ?g construct allows a pattern to match against one of the named graphs in the RDF dataset. The URI of the matching graph is bound to ?g (or whatever variable was actually used).
N.B. The FILTER assures that we're finding a person who occurs in three distinct graphs.
N.B. The Web interface we use for this SPARQL query defines the foaf: prefix, which is why we omit it here.

Try it with the data.semanticweb.org SPARQL endpoint. (Expected results.)

Query #10: Tranforming between vocabularies

Convert FOAF data to VCard data.

PREFIX vCard: <http://www.w3.org/2001/vcard-rdf/3.0#>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
CONSTRUCT { 
  ?X vCard:FN ?name .
  ?X vCard:URL ?url .
  ?X vCard:TITLE ?title .
}FROM <http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf>
WHERE { 
  OPTIONAL { ?X foaf:name ?name . FILTER isLiteral(?name) . }
  OPTIONAL { ?X foaf:homepage ?url . FILTER isURI(?url) . }
  OPTIONAL { ?X foaf:title ?title . FILTER isLiteral(?title) . }
}

CONSTRUCT is an alternative SPARQL result clause to SELECT. Instead of returning a table of result values, CONSTRUCT returns an RDF graph.
The result RDF graph is created by taking the results of the equivalent SELECT query and filling in the values of variables that occur in the CONSTRUCT template.
Triples are not created in the result graph for template patterns that involve an unbound variable.

Try it with ARQ or OpenLink's Virtuoso. (Expected results.)

Query #11: ASKing a question

Is the Amazon river longer than the Nile River?

PREFIX prop: <http://dbpedia.org/property/>
ASK
{
  <http://dbpedia.org/resource/Amazon_River> prop:length ?amazon .
  <http://dbpedia.org/resource/Nile> prop:length ?nile .
  FILTER(?amazon > ?nile) .
}

The ASK result clause simply returns true or false depending on whether or not the query pattern has any matches in the dataset.
As with SELECT queries, the boolean result is (by default) encoded in an SPARQL Results Format XML document.
Shortcut: the WHERE keyword is optional--not only in ASK queries but in all SPARQL queries.

Try it with the Virtuoso DBPedia SPARQL endpoint. (Expected results. - or are they??)

Dataset: EDGAR Corporate Ownership Data

rdfabout.com hosts an RDF dataset of U.S. corporate ownership data from the U.S. Security & Exchange Commission's EDGAR database.
This dataset contains about one million triples describing corporations, board members, officers, and significant (greater than 10%) ownership relationships.

Query #12: Learning about a resource

Tell me whatever you'd like to tell me about the Ford Motor Company.

PREFIX foaf:  <http://xmlns.com/foaf/0.1/>
DESCRIBE ?ford WHERE {
  ?ford foaf:name "FORD MOTOR CO" .
}

The DESCRIBE query result clause allows the server to return whatever RDF it wants that describes the given resource(s).
Because the server is free to interpret DESCRIBE as it sees fit, DESCRIBE queries are not interoperable.
Common implementations include concise-bounded descriptions, named graphs, minimum self-contained graphs, and more.

Note: The EDGAR-specific SPARQL endpoint is not currently up. (Expected results.)

What's new in SPARQL 1.1 Query?

A new SPARQL WG was chartered in March 2009 to extend the SPARQL language and landscape. SPARQL 1.1 Query includes these extensions:

Projected expressions. SPARQL 1.1 Query adds the ability for query results to contain values derived from constants, function calls, or other expressions in the SELECT list.
Aggregates. SPARQL 1.1 Query adds the ability to group results and calculate aggregate values (e.g. count, min, max, avg, sum, ...).
Subqueries. SPARQL 1.1 Query allows one query to be embedded within another.
Negation. SPARQL 1.1 Query includes improved language syntax for querying negations.
Property paths. SPARQL 1.1 Query adds the ability to query arbitrary length paths through a graph via a regular-expression-like syntax known as property paths.
Basic federated query. SPARQL 1.1 Query defines a mechanism for splitting a single query among multiple SPARQL endpoints and combining together the results from each.

Query #13: Projected Expressions

How many neutrons does the most common isotope of each element have?

PREFIX :   <http://www.daml.org/2003/01/periodictable/PeriodicTable#>
SELECT ?element ?protons (ROUND(?weight) - ?protons AS ?neutrons)
FROM <http://www.daml.org/2003/01/periodictable/PeriodicTable.owl>
WHERE {
  [] a :Element ;
    :atomicNumber ?protons ;
    :atomicWeight ?weight ;
    :name ?element .
} ORDER BY ?protons

Projected expressions allows for arbitrary expressions to be used for columns in a query's result set.
Projected expressions must be in parentheses and must be given an alias using the AS keyword.
Note: [] in a query acts as an unnamed variable.

Try it with sparql.org. (Expected results.)

Dataset: UK Government Data

The UK Government publishes government data on http://data.gov.uk/
The data includes 3,342 data sets from 21 public agencies that cover analytic, education, environment, finance, transportation, and statutory data
The site also includes a SPARQL endpoint

Query #14: Aggregates

How many roads of each classification are there in the UK?

PREFIX skos: <http://www.w3.org/2004/02/skos/core#>
PREFIX roads: <http://transport.data.gov.uk/def/traffic/>
SELECT ?cat (COUNT(DISTINCT ?thing) AS ?roads)
WHERE {
   ?thing  a roads:Road ; roads:countPointRoadCategory ?cat .
}
GROUP BY ?cat

Aggregate queries post-process query results by dividing the solutions into groups, and then performing summary calculations on those groups.
As in SQL, the GROUP BY clause specifies the key variable(s) to use to partition the solutions into groups.
SPARQL 1.1 defines these aggregate functions: COUNT, MIN, MAX, SUM, AVG, GROUP_CONCAT, SAMPLE
SPARQL 1.1 also includes a HAVING clause to filter the results of the query after applying aggregates.

Try it with the data.gov.uk endpoint. Make sure to choose the Transport dataset. (Expected results.)

Query #15a: Limit Per Resource Without Subqueries

Retrieve the second page of names and emails of people in Tim Berners-Lee's FOAF file, given that each page has 10 people.

PREFIX foaf:  <http://xmlns.com/foaf/0.1/>
SELECT ?name ?email
FROM <http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf>
WHERE {
    ?person foaf:name ?name .
    OPTIONAL { ?person foaf:mbox ?email }
} ORDER BY ?name LIMIT 10 OFFSET 10

Simple--just use the LIMIT and OFFSET clauses to get the second set of ten.
Try it with ARQ. (Expected results.)
How many rows are in the results? But how many people are in the results?

Query #15b: Limit Per Resource With Subqueries

Retrieve the second page of names and emails of people in Tim Berners-Lee's FOAF file, given that each page has 10 people.

PREFIX foaf:  <http://xmlns.com/foaf/0.1/>
SELECT ?name ?email
FROM <http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf>
WHERE {
    {      SELECT DISTINCT ?person ?name WHERE { 
        ?person foaf:name ?name 
      } ORDER BY ?name LIMIT 10 OFFSET 10    }
    OPTIONAL { ?person foaf:mbox ?email }
}

We want to limit the people, not the result set rows
The subquery lets us do exactly that, before retrieving any email addresses for the 10 people selected
Try it with ARQ. (Expected results.)

Query #16a: Negation In SPARQL 1.0

Find the person entries in Tim Berners-Lee's FOAF file that do not contain a URL for the person's FOAF file.

PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT ?name
FROM <http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf>
WHERE {
  ?person a foaf:Person ; foaf:name ?name .
  OPTIONAL { ?person rdfs:seeAlso ?url }
  FILTER(!bound(?url))
}

Negation in SPARQL 1.0 was done using OPTIONAL, the bound filter, and the logical-not operator.
The OPTIONAL clause binds a variable in cases we want to exclude, and the filter removes those cases.
This is awkward at best.
Try it with ARQ. (Expected results.)

Query #16b: Negation In SPARQL 1.1 (Part 1)

Find the person entries in Tim Berners-Lee's FOAF file that do not contain a URL for the person's FOAF file.

PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT ?name
FROM <http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf>
WHERE {
  ?person a foaf:Person ; foaf:name ?name .
  MINUS { ?person rdfs:seeAlso ?url }
}

SPARQL 1.1 includes a MINUS graph pattern clause: a binary operator that removes bindings that match the right-hand side.
Try it with ARQ. (Expected results.)

Query #16c: Negation In SPARQL 1.1 (Part 2)

Find the person entries in Tim Berners-Lee's FOAF file that do not contain a URL for the person's FOAF file.

PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT ?name
FROM <http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf>
WHERE {
  ?person a foaf:Person ; foaf:name ?name .
  FILTER(NOT EXISTS { ?person rdfs:seeAlso ?url })
}

SPARQL 1.1 includes a NOT EXISTS filter that uses the bindings from a solution to test whether or not a given graph pattern exists.
In most cases, negation can be done with either MINUS or NOT EXISTS -- there are some differences in edge cases, though!
Try it with ARQ. (Expected results.)

Query #17a: Finding Beers

Find all of the beers included in the beer ontology.

PREFIX beer: <http://www.w3.org/2011/12/beer.owl#>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT ?beer
FROM <http://www.w3.org/2011/12/beer.owl>
WHERE {
   ?beer rdf:type beer:Beer .
}

Simple--just find all resources of the beer type.
Try it with ARQ. (Expected results.)
Why do we get no results?
The beer ontology makes heavy use of inferences; nothing is explicitly typed as a beer:Beer.

Query #17b: Finding Beers, Revisited

Find all of the beers included in the beer ontology.

PREFIX beer: <http://www.w3.org/2011/12/beer.owl#>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT ?beer
FROM <http://www.w3.org/2011/12/beer.owl>
WHERE {
   ?beer rdf:type/rdfs:subClassOf* beer:Beer .
}

Property paths let us query for arbitrary-length paths through the dataset graphs.
Property paths reuse syntax from regular expressions.
Try it with ARQ. (Expected results.)

Query #18: Federate Data From Two Endpoints

Find the birth dates of all of the actors in Star Trek: The Motion Picture

PREFIX movie: <http://data.linkedmdb.org/resource/movie/>
PREFIX dbpedia: <http://dbpedia.org/ontology/>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
SELECT ?actor_name ?birth_date
FROM <http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf> # placeholder graph
WHERE {
  SERVICE <http://data.linkedmdb.org/sparql> {
    <http://data.linkedmdb.org/resource/film/675> movie:actor ?actor .
    ?actor movie:actor_name ?actor_name
  }
  SERVICE <http://dbpedia.org/sparql> {
    ?actor2 a dbpedia:Actor ; foaf:name ?actor_name_en ; dbpedia:birthDate ?birth_date .
    FILTER(STR(?actor_name_en) = ?actor_name)
  }
}

The SERVICE keyword is used to send part of a query against a remote SPARQL endpoint.
Note: SPARQL 1.1 defines a mechanism to communicate results from one endpoint to another, but this is not currently widely deployed.
The FILTER is necessary because names in dbpedia have language tags, while names in LinkedMDB do not.
Try it with ARQ. (Expected results.)

What else is new in SPARQL 1.1?

The new SPARQL WG is also extending the SPARQL landscape with:

Update. SPARQL 1.0 Query is a read-only query language. SPARQL 1.1 Update defines a language to manipulate and update RDF graphs.
Graph Store HTTP Protocol. A mapping from RESTful HTTP requests to the corresponding SPARQL 1.1 Update operations.
Service description. A discovery mechanism and vocabulary for describing the capabilities of a SPARQL endpoint.
SPARQL with other entailment regimes. Standard semantics for the interactions between SPARQL and OWL, RDF Scehma, and RIF.

SPARQL 1.1 Update

SPARQL 1.1 Update is a language for managing and updating RDF graphs.

INSERT DATA { triples }
DELETE DATA { triples }
[ DELETE { template } ] [ INSERT { template } ] WHERE { pattern }
LOAD uri [ INTO GRAPH uri ]
CLEAR GRAPH uri
CREATE GRAPH uri
DROP GRAPH uri

SPARQL 1.1 Graph Store HTTP Protocol

The SPARQL 1.1 Graph Store HTTP Protocol defines how to use RESTful HTTP requests to affect an RDF graph store. Some examples:

HTTP PUT of RDF data to a URI u means:

DROP GRAPH u;
CREATE GRAPH u;
INSERT DATA { GRAPH u { ... RDF payload ... } }

HTTP DELETE to a URI u means:
```
DROP GRAPH u
```

HTTP POST of RDF data to a URI u means:

INSERT DATA { GRAPH u { ... RDF payload ... } }

HTTP GET to a URI u means:

CONSTRUCT { ?s ?p ?o } WHERE { GRAPH u { ?s ?p ?o } }

SPARQL 1.1 Service Description

The SPARQL 1.1 Service Description defines a discovery mechanism and vocabulary for describing the capabilities and data available at a SPARQL endpoint.

Discovery. A service description is retrieved by doing an HTTP GET on the endpoint's URL. It may be returned as RDFa or any other RDF serialization.
Vocabulary. The SPARQL 1.1 Service Description vocabulary describes functions, aggregates, features, graphs, entailment regimes, property functions, result formats, and more.

What's missing from SPARQL?

Even with the ongoing SPARQL 1.1 work, there are several other pieces of the SPARQL landscape that are not yet standardized, including:

Full-text search. How is keyword/key-phrase search integrated with SPARQL queries?
Parameters. How can initial bindings be supplied to a SPARQL endpoint along with the query itself?
Querying "all" named graphs. Is there a standard way to ask that a SPARQL query be run against all the graphs that a SPARQL endpoint knows about?
SPARQL in XML and RDF. Several toolsets make use of XML- or RDF-based serializations of SPARQL queries.

The W3C ESW wiki lists more SPARQL extensions.

Query #19: SPARQL extension: free-text search

Find me countries with 'Republic' in their name that were established before 1920.

PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>        
PREFIX type: <http://dbpedia.org/class/yago/>
PREFIX prop: <http://dbpedia.org/property/>
SELECT DISTINCT ?lbl ?est
WHERE {
  ?country rdfs:label ?lbl .
  FILTER(bif:contains(?lbl, "Republic")) .
  ?country a type:Country108544813 ;
      prop:establishedDate ?est .
  FILTER(?est < "1920-01-01"^^xsd:date && langMatches(lang(?lbl), "EN")) .
}

OpenLink's Virtuoso uses an extension filter function, bif:contains to filter literal values against a free-text index. Other implementations use other techniques.

Try it with the Virtuoso DBPedia SPARQL endpoint. (Expected results.)
