Class NSPrefixMappings

java.lang.Object

it.uniroma2.art.semanticturkey.ontology.NSPrefixMappings

public class NSPrefixMappings
extends Object

This class realizes a File-persisted manager for namespace-prefix mappings, adopted inside Semantic Turkey projects
This system has an in-memory representation of the map, which is regularly persisted to file; its sync is managed internally. On the contrary, this manager does not syncs automatically with the prefix-namespace mappings held inside an RDF4J repository. This latter sync is managed by the {@link {@link STOntologyManager}
