OWL language mapping for ontologies in the OBO flat file format 1.4

Actions Codecov License Source Crate Documentation Changelog GitHub issues DOI

Overview

This library provides an implementation of the OBO to OWL mappings for the OBO format version 1.4 ontology language. It can be used to produce a semantically-equivalent OWL ontology from any OBO ontology.

Usage

Add fastobo-owl to the [dependencies] sections of your Cargo.toml manifest:

[dependencies]
fastobo-owl = "0.2.1"

Then use the IntoOwl trait to convert an OboDoc into any OWL ontology (the output type must implement the Default, Ontology and MutableOntology traits). Here's a how you could write a very simple script to load an OBO document from a file, convert it to OWL, and write it to another file in OWL/XML syntax:

extern crate fastobo;
extern crate fastobo_owl;

use fastobo_owl::IntoOwl;

// load an OBO ontology from a file
let obo = fastobo::from_file("tests/data/ms.obo").expect("failed to read OBO file");

// extract prefixes from the OBO header, so that they can be used
// to build abbreviated IRIs when serializing the OWL output
// (note: this contains OBO default prefixes such as xsd, rdf, or oboInOwl)
let prefixes = obo.prefixes();

// convert the ontology to OBO (the ontology type is implied by the later
// call to owx::writer::write which expects an `AxiomMappedOntology`)
let owl = obo.into_owl()
  .expect("failed to convert OBO to OWL");

// write the OWL ontology with abbreviated IRIs
let mut output = std::fs::File::create("tests/data/ms.owx").unwrap();
horned_owl::io::owx::writer::write(&mut output, &owl, Some(&prefixes));
