 *Horned-OWL* is a library for processing and manipulating documents written using the [Web Ontology Language (OWL)](https://en.wikipedia.org/wiki/Web_Ontology_Language).
 
 It extends the existing ecosystem of Rust crates for the Semantic Web and provides tools to interact with OWL ontologies within Rust applications.
-It leverages the features of Rust to be performant and competitive against other libraries for ontologies manipulation, such as the [OWL API](https://github.com/owlcs/owlapi). Horned-OWL is aimed at allowing ontologies

-## Features
-
-+ Supports the OWL 2 language as specified in the [W3C Recommendation](https://www.w3.org/TR/owl-overview/)
-+ Supports the Semantic Web Rule Language as specified in the [W3C User Submission](https://www.w3.org/submissions/SWRL/)
-+ Supports serialization/deserialization of the following OWL syntaxes:
++ Support for the OWL 2 language as specified in the [W3C Recommendation](https://www.w3.org/TR/owl-overview/)
++ Support for the Semantic Web Rule Language as specified in the [W3C User Submission](https://www.w3.org/submissions/SWRL/)
++ Support for serialization/deserialization of the following OWL syntaxes:
   + [x] RDF/XML
   + [x] OWL/XML
   + [x] Functional Syntax
   + [ ] Manchester Syntax
-+ Provides a [visitor](https://en.wikipedia.org/wiki/Visitor_pattern) trait to navigate and manipulate ontologies
-+ Provides traits and implementations for several types of ontologies

+## Features
 
++ `encoding`: enables the `encoding` feature for the [quick-xml](https://crates.io/crates/quick-xml) dependency, expanding support to non-UTF-8 encoded documents while parsing OWL/XML.
++ `remote`: enables the resolution of non-local imports while parsing RDF/XML.
 ## Performance
 
 We test the performance of our crate in validating large ontologies (e.g. the Gene Ontology) against competing implementations based on the OWL API. Preliminary results are encouraging, showing a potential speedup of 20x-40x.
