Example queries

Datasource oriented queries

Get all datasource currently captured in WikiPathways
select distinct ?datasource count(?datasource) as ?numberEntries 
 WHERE {
         ?concept dc:source ?datasource
} 
Execute
Get the number of entries per datasource in WikiPathways
SELECT DISTINCT ?datasource 
WHERE {
      ?concept dc:source ?datasource
}  
Execute
Count the identifiers per data source
SELECT DISTINCT ?datasource ?identifier count(?identifier) AS ?numberEntries 
WHERE {
        ?concept dc:source ?datasource .
        ?concept dc:identifier ?identifier
} 
Execute
Count the identifiers per data source and order them from high to low
SELECT DISTINCT ?datasource ?identifier count(?identifier) AS ?numberEntries 
WHERE {
        ?concept dc:source ?datasource .
        ?concept dc:identifier ?identifier
} 
ORDER BY DESC(?numberEntries)
Execute

Curators oriented queries

Extract contributors
SELECT DISTINCT ?contributor  
WHERE {
       ?pathway dc:contributor ?contributor
}
Execute
Extract the amount of pathways edited per contributor
SELECT DISTINCT ?contributor, count(?pathway) as ?pathwaysEdited  
WHERE {
       ?pathway dc:contributor ?contributor
}
ORDER BY DESC(?pathwaysEdited)
Execute
find the pathways a user have edited so far. Change the name in the query
SELECT DISTINCT ?pathway, ?pathwayLabel
WHERE {
       ?pathway dc:contributor wpuser:Andra .
       ?pathway dc:contributor ?contributor .
       ?pathway rdfs:label ?pathwayLabel .
}
Execute
