On this page we collect SPARQL queries to see the state of the Metabolome in WikiPathways. Triggered by User:Andra's RDF / SPARQL work, curation started with metabolites without database identifiers. But this soon led to the observation that metabolites are often not even annotated as being a metabolite (using <Label> rather than <DataNode>). Therefore, User:Egonw started at Pathway:WP1 to curate them one by one and fix these issues:
- connect lines between metabolites
- convert metabolites to use <Label> rather than <DataNode>
The reason for this is that these are some basic underlying properties we need for metabolomics research fields.

Metabolome
The following queries provide an overview of the Metabolome captures by WikiPathways.
The key type for metabolites is the wp:Metabolite. We can see all available properties with:
prefix wp: <http://vocabularies.wikipathways.org/wp#>
select distinct ?p where {
?mb a wp:Metabolite ;
?p [] .
}
To only get analysis of the most recent pathways, add this snippet to your SPARQL, assuming ?pathway is the used variable name:
?mb dcterms:isPartOf ?pathway . ?mb dcterms:isPartOf ?pathway2 . ?pathway2 pav:version ?version2 . FILTER (?version2 > ?version)

select ?mb ?label where {

Metabolic Data Sources
Sorted by use

prefix dcterms: <http://purl.org/dc/terms/>
select ?datasource count(?identifier) as ?count
where {
?mb a wp:Metabolite ;
dc:source ?datasource ;
dc:identifier ?identifier .
} order by desc(?count)
All metabolites from one source
All KEGG identifiers
prefix wp: <http://vocabularies.wikipathways.org/wp#>
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
prefix dcterms: <http://purl.org/dc/terms/>
select distinct ?identifier

dc:identifier ?identifier .
FILTER (!isIRI(?identifier))
} order by ?identifier
All HMDB identifiers

prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
prefix dcterms: <http://purl.org/dc/terms/>

FILTER (!isIRI(?identifier))
} order by ?identifier
Metabolic Pathways
Curation
Metabolites not classified as such
One can list all data sources for non-metabolites with this query:
prefix wp: <http://vocabularies.wikipathways.org/wp#>
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
prefix dcterms: <http://purl.org/dc/terms/>
select ?datasource count(?identifier) as ?count
where {
?mb dc:source ?datasource ;
dc:identifier ?identifier .
FILTER NOT EXISTS { ?mb a wp:Metabolite }
} order by desc(?count)
That mostly lists gene identifier sources, etc, but watch out for the metabolite identifier data sources. For example, metabolites not marked as such but with a metabolite identifier can be found this way.
Non-Metabolites with CAS identifier
Note that a CAS identifier can also refer to mixtures, compound classes, etc.
prefix wp: <http://vocabularies.wikipathways.org/wp#>
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
prefix dcterms: <http://purl.org/dc/terms/>
prefix xsd: <http://www.w3.org/2001/XMLSchema#>
select distinct ?pathway ?mb ?identifier
where {
?mb dc:source "CAS"^^xsd:string ;
dc:identifier ?identifier ;
dcterms:isPartOf ?pathway .
FILTER NOT EXISTS { ?mb a wp:Metabolite }
FILTER (!isIRI(?identifier))
} order by ?pathway
Non-Metabolites with PubChem identifier
These might have been curated by the time of reading.
prefix wp: <http://vocabularies.wikipathways.org/wp#>
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
prefix dcterms: <http://purl.org/dc/terms/>
prefix xsd: <http://www.w3.org/2001/XMLSchema#>
select distinct ?pathway ?mb ?identifier
where {
?mb dc:source "PubChem"^^xsd:string ;
dc:identifier ?identifier ;
dcterms:isPartOf ?pathway .
FILTER NOT EXISTS { ?mb a wp:Metabolite }
FILTER (!isIRI(?identifier))
} order by ?pathway
Metabolites with an identifier but undefined data source
prefix wp: <http://vocabularies.wikipathways.org/wp#>
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
prefix dcterms: <http://purl.org/dc/terms/>
prefix xsd: <http://www.w3.org/2001/XMLSchema#>
select distinct ?pathway ?mb ?identifier
where {
?mb a wp:Metabolite ;
dc:source ""^^xsd:string ;
dc:identifier ?identifier ;
dcterms:isPartOf ?pathway .
FILTER (!isIRI(?identifier))
FILTER (str(?identifier) != "")
} order by ?pathway
Metabolites with an Entrez Gene identifier
prefix wp: <http://vocabularies.wikipathways.org/wp#> prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> prefix dcterms: <http://purl.org/dc/terms/> prefix xsd: <http://www.w3.org/2001/XMLSchema#>
select distinct ?pathway ?mb ?identifier where {
?mb a wp:Metabolite ; dc:source "Entrez Gene"^^xsd:string ; dc:identifier ?identifier ; dcterms:isPartOf ?pathway . FILTER (!isIRI(?identifier)) FILTER (str(?identifier) != "")
} order by ?pathway
