Before using the BioPortal SPARQL service please read our SPARQL_Release_Notes_And_Usage_Policy


Web Interface and Query Examples

There is a Web interface to test SPARQL queries at

Also, interactive examples can be tested at the following page

Submitting SPARQL queries programmatically

A github project contains examples to query our SPARQL service programmatically:

A tarball with these examples is for download here:

This project contains examples in Java, Python, JavaScript and Perl. Some of the examples use just language built-in capabilities and other need third-party libraries like Jena, Sesame or SPARQLWrapper. The github project and the tarball are self-contained, no need to download and install extra libraries.

To run these examples or any other SPARQL queries programmatically an API key from BioPortal is required. If you do not have a BioPortal account go to [New Account] and create one. Once you have the BioPortal account, login in BioPortal and go to your account details. You should see your API Key as part of your account profile.
