Parameters:

url - a URL where the OWL file is stored

cacheName - unique name of this ontology, will be used to load from disk in case of failed url connection

hasChanged

public static boolean hasChanged(String cacheName)

deleteOldCache

openConnection

public static URLConnection openConnection(String url)

getDiskCachePath

public static File getDiskCachePath(String name)

Obtain the path for the ontology cache.
