OntoSpy

RDFLIb-based Python toolkit for inspecting ontologies on the Semantic Web.

Description

OntoSpy is a lightweight Python library and command line tool for inspecting and visualizing vocabularies encoded using W3C Semantic Web standards (aka ontologies).

The basic workflow is simple: load a graph by instantiating the Graph class with a file containing RDFS, OWL or SKOS definitions. You get back an object that lets you interrogate the ontology. That's all!

The same functionalities are accessible also via a handy command line application (ontospy). This is an interactive environment (like a repl) that allows to load ontologies from a local repository, interrogate them and cache them so that they can be quickly reloaded for inspection later on.
