WebRDFLib is a pure Python package for working with RDF. RDFLib contains most things you need to work with RDF, including: parsers and serializers for RDF/XML, N3, NTriples, N-Quads, Turtle, TriX, Trig and JSON-LD & HexTuples a Graph interface which can be backed by any one of a number of Store implementations many store implementations WebFeatures: RDF model storage: RDFlib supports the storage of RDF models in several possible backends, including an in-memory store by default. SPARQL support: RDFlib contains a complete implementation of SPARQL 1.1 (Query and Update). Reasoning/Inference: The OWL-RL library supports inference for the RDFS and OWL-RL ontology languages.

WebExperience building domain ontologies based on a top-level ontology. Comfort with weighing tradeoffs between semantic expressivity and project-specific implementation strategies. Experience with any of the following: Basic Formal Ontology (BFO); ontologies in the OBO Foundry; other semantic web standards, such as Dublin Core, SKOS, QUDT, etc. WebI installed the python rdflib(sudo pip install rdflib) and rendered it with ontology-visualization: python ./ontology_viz.py -o test.dot test.ttl -O ontology.ttl[WARNING] Class http://dig.isi.edu/Time_Span doesn't exist in the ontology! [WARNING] Property http://dig.isi.edu/at_some_time_within_date doesn't exist in the ontology! WebNote that NXOntology represents the ontology as a networkx.DiGraph, where edge direction goes from superterm to subterm. Given an NXOntology instance, here how to compute intrinsic similarity metrics. from nxontology. examples import create_metal_nxo metals = create_metal_nxo () # Freezing the ontology prevents adding or removing nodes or edges ... hilton pdx airport
