The first subquery retrieved all directed metabolic reactions, limited to the species Homo sapiens, with the corresponding Wikidata identifier for these metabolites (and if available the ChEBI and HMDB identifier). This query is depicted in Code Example 2, and divided into six parts for clarity (note that the required prefixes for Blazegraph have been omitted, these are identical to the first part in Code Example 1). The first part describes which properties were retrieved from the RDF. The second part retrieves the identifier and title of the pathway, filtering for human pathways only (note that there are currently more than 30 species available in WikiPathways and that identifiers for metabolites are not species-specific). The third part provides three options: when statement 3A was used, pathways were filtered for the (curated) Analysis Collection; statement 3B filtered for pathways from the Reactome collection; statement 3C filtered for the LIPID MAPS collection; when all three statements were omitted, all pathways were retrieved, regardless of curation status.
