Current revision
On http://sparql.wikipathways.org/ WikiPathways content is replicated in a SPARQL endpoint. Queries can be performed in three ways:
1. Either go to the endpoint directly and create your own SPARQL query.
2. Copy and paste an example query listed below in the endpoint.
3. Adapt a code examples to programmatically make a SPARQL query
This project is written up in the "Using the Semantic Web for Rapid Integration of WikiPathways with Other Biological Online Data Resources" paper.
NOTIFICATION: Due to an Apache update, we are now creating RDF data according to SPARQL 1.1. However, our SPARQL-endpoint running on Virtuoso is still using SPARQL 1.0. This influences the way to query strings, and might affect federated queries. Please remove the ^^xsd:string suffix, as shown in the example below.
Resources
- WikiPathways internal vocabularies: http://vocabularies.wikipathways.org
- WikiPathways SPARQL endpoint https://sparql.wikipathways.org/sparql
- Identifiers.org: https://identifiers.org
- Searches prefixes: http://prefix.cc

Prefixes
Within the example queries, we have omitted the prefixes. These prefixes are automatically used in the SPARQL endpoint. The following prefixes are used in the WikiPathways RDF:
PREFIX gpml: <http://vocabularies.wikipathways.org/gpml#> PREFIX wp: <http://vocabularies.wikipathways.org/wp#> PREFIX cur: <http://vocabularies.wikipathways.org/wp#Curation:> PREFIX wprdf: <http://rdf.wikipathways.org/> PREFIX biopax: <http://www.biopax.org/release/biopax-level3.owl#> PREFIX cas: <https://identifiers.org/cas/> PREFIX dc: <http://purl.org/dc/elements/1.1/> PREFIX dcterms: <http://purl.org/dc/terms/> PREFIX foaf: <http://xmlns.com/foaf/0.1/> PREFIX ncbigene:<https://identifiers.org/ncbigene/> PREFIX pubmed: <http://www.ncbi.nlm.nih.gov/pubmed/> PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX skos: <http://www.w3.org/2004/02/skos/core#> PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
Example queries
Queries with a * require a bit more time for results.
Metadata queries
List the information about the data sets in the SPARQL endpoint:
select distinct ?dataset (str(?titleLit) as ?title) ?date ?license where {
?dataset a void:Dataset ;
dcterms:title ?titleLit ;
dcterms:license ?license ;
pav:createdOn ?date .
}
Pathway oriented queries
Get the species currently in WikiPathways with their respective URI's
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX wp: <http://vocabularies.wikipathways.org/wp#>
SELECT DISTINCT ?organism (str(?label) as ?name)
WHERE {
?concept wp:organism ?organism ;
wp:organismName ?label .
}
List pathways and their species
PREFIX dc: <http://purl.org/dc/elements/1.1/>
PREFIX wp: <http://vocabularies.wikipathways.org/wp#>
SELECT DISTINCT (str(?title) as ?pathway) (str(?label) as ?organism)
WHERE {
?pw dc:title ?title ;
wp:organism ?organism ;
wp:organismName ?label .
}
List the species captured in WikiPathways and the number of pathways per species
PREFIX dc: <http://purl.org/dc/elements/1.1/>
PREFIX wp: <http://vocabularies.wikipathways.org/wp#>
SELECT DISTINCT ?organism (str(?label) as ?name) (count(?pw) as ?pathwayCount)

?pw dc:title ?title ;
wp:organism ?organism ;
wp:organismName ?label .
}
ORDER BY DESC(?pathwayCount)
List all pathways for species "Mus musculus"
The following query list all mouse pathways. ?wpIdentifier is the link through identifiers.org, ?pathway points to the RDF version of WikiPathways and ?page is the revision which is loaded in the SPARQL endpoint.

In WikiPathways, pathways can be tagged with ontology terms from Pathway, Cell Line and Disease ontology. The following query returns a pathway count for each term from any of the available ontologies.

Other gene IDs can be used to fill the list. However, keep in mind they use different URLs and therefore the prefix (first line of query) should be adapted. A list of these URLs can be found on identifiers.org (or by looking at the "raw" RDF files).

Data statistics oriented queries

Though strictly speaking, it guesstimates it, because it counts the number of unique metabolite identifiers.

Check the full list, to see which databases normally used for chemicals are not typed as Metabolites. Gene identifier sources are most likely at the bottom. Note: Wikidata can be used for Metabolites, Proteins, and Genes (but is preferably used only for Metabolites, since there are no mappings available yet to map to other gene databases).

Metabolites sometimes marked as DataNode@Type Metabolite
Based on label comparisons, we can find things that are labeled the same as a data node with the same label. Of course, this can give false positives, because genes can be incorrectly marked as metabolite in some pathway, but that is another SPARQL query. Another reasons is that sometimes genes and metabolites actually have the same name!

WikiPathways with EBI Atlas RDF
Unfortunately, this data is no longer hosted on a SPARQL endpoint by EBI (so the federated queries will not work).
Genes differentially expressed in asthma and Pathways
For the genes differentially expressed in asthma, get the gene products associated to a WikiPathways pathway. (Built upon example query 5 in: http://www.ebi.ac.uk/rdf/services/atlas/sparql ). You can substitute the EFO number for other disease codes.

WikiPathways with Wikidata - !Under Construction!
The following queries are run on the WikiPathways SPARQL endpoint. But you can run federated queries on the Wikidata SPARQL endpoint too. Example queries for that are found here.

Code examples
Perl
There is an RDF api available. Below is an example that extracts the data by converting the query into a url and extracts the data as CSV.
#!/usr/bin/perl
use LWP::Simple;
use URI::Escape;
my $sparql = "SELECT DISTINCT ?wpIdentifier ?elementneedsattention ?elementLabel

?pathway foaf:page ?page .
?pathway dc:identifier ?wpIdentifier .
?organism rdfs:label \"Mus musculus\"^^<http://www.w3.org/2001/XMLSchema#string> .
}
ORDER BY ?wpIdentifier";
my $url = 'https://sparql.wikipathways.org/sparql?default-graph-uri=&query='.uri_escape($sparql).'&format=text%2Fcsv&timeout=0&debug=on';
my $content = get $url;
die "Couldn't get $url" unless defined $content;
print $content;
Java
For java we recommend the Jena Framework.
import com.hp.hpl.jena.query.Query;
import com.hp.hpl.jena.query.QueryExecution;
import com.hp.hpl.jena.query.QueryExecutionFactory;
import com.hp.hpl.jena.query.QueryFactory;
import com.hp.hpl.jena.query.QuerySolution;
import com.hp.hpl.jena.query.ResultSet;
public class javaCodeExample {
public static void main(String[] args) {
String sparqlQueryString = "SELECT * WHERE {?s ?p ?o} LIMIT 10";
Query query = QueryFactory.create(sparqlQueryString);
QueryExecution queryExecution = QueryExecutionFactory.sparqlService("https://sparql.wikipathways.org/sparql", query);
ResultSet resultSet = queryExecution.execSelect();
while (resultSet.hasNext()) {
QuerySolution solution = resultSet.next();
System.out.print(solution.get("s"));
System.out.print("\t"+solution.get("p"));
System.out.println("\t"+solution.get("o"));
}
}
}
php
For php we recommend the arc2: Easy RDF and SPARQL for LAMP systems
R
The R package rrdf can be found and installed from https://github.com/egonw/rrdf.
library(rrdf)
sparql.remote(
"https://sparql.wikipathways.org/sparql",
"SELECT DISTINCT ?p WHERE { ?s ?p ?o }"
)
Another option is to use the SPARQL-package (tested on Ubuntu 18.04.5 LTS, R-studio version 1.4.1717, R version 4.1.0 (2021-05-18)).
- Note the backslashes in front of the quotation marks in the VALUES claim; this is specifically needed in R to read these characters correctly.
- Note this query is an example of how to perform a UNION query in WikiPathways.
if(!"SPARQL" %in% installed.packages()){
install.packages("SPARQL")
}
library(SPARQL)

Bioclipse
The below code works in both the JavaScript and the Groovy console:
rdf.sparqlRemote(
"https://sparql.wikipathways.org/sparql",
"SELECT DISTINCT ?p WHERE { ?s ?p ?o }"
)
SPARQL from the command line
For quick and easy querying, we recommend to use curl (Linux and OS X)
curl -F "query=SELECT * WHERE {?s ?p ?o} LIMIT 10" https://sparql.wikipathways.org/sparql
