ontocast.cli.merge_ontologies

CLI script to merge terminal ontologies from Fuseki.

This script: 1. Fetches all terminal ontologies for a given IRI from Fuseki 2. Merges them pair-wise starting from the oldest pair 3. Continues until only one terminal ontology per IRI remains 4. Plots the ontology graph using pygraphviz

main(env_file, iri, output)

Merge terminal ontologies from Fuseki and plot the result.
