From WikiPathways

Two subsets of pathways from WikiPathways are now available in the RDF format: the Curated and the Reactome collections. For the curated collection a set of interactions are also available. Updates are currently not immediate. Meaning that if you add a new pathway or edit an existing one these updates will not be available in the RDF immediately. We do test builds of the RDF daily though. If you need an RDF update please contact us (on the mailing is best) and we can see what can be done.

Download RDF

The RDF can be downloaded.

Open PHACTS API

The Open PHACTS projects provides an alternative to work with the WikiPathways RDF, as it is loaded in the data cache of Open PHACTS. The Open PHACTS API provides various queries, like "give me all targets in a pathway". It requires a (free) account to use this system.

SPARQL Endpoint

There is also an (experimental) SPARQL endpoint where data queries can be done. Example queries are available from this page.
