# How to use the RDF ontology database

We demonstrate what it takes to enable the discovery and retrieval of data about the environmental context, functional genomic potential, and taxonomic structure of the marine prokaryotic microbiome through an API service.&#x20;

The service can be used following the instructions detailed in the protocols.io: [http://dx.doi.org/10.17504/protocols.io.e6nvwkw19vmk/v2](http://dx.doi.org/10.17504/protocols.io.e6nvwkw19vmk/v2)
