Method Detail

addImport

public static void addImport(org.eclipse.core.resources.IFile file,
                             org.eclipse.core.runtime.IProgressMonitor monitor)
                      throws java.lang.Exception

Adds an import from a local file to the currently selected model. The input file must be registered in the FileRegistry.

Parameters:

file - the file to import from

Throws:

java.lang.Exception

addImport

public static void addImport(java.net.URI importedURI,
                             org.eclipse.core.runtime.IProgressMonitor monitor)
                      throws java.lang.Exception

Adds an import from a URL to the currently selected model. The URL is derived from a URI, i.e. the provided URI must be identical with the physical location.

Parameters:

importedURI - the URI to import from

Throws:

java.lang.Exception

getMissingImports

public static java.util.Set<java.net.URI> getMissingImports(com.hp.hpl.jena.ontology.OntModel ontModel)

Tries to "guess" missing imports to get completely typed models. The method suggests the namespaces of those untyped resources that are used in "critical" triples, such as rdfs:subClassOf or as predicate in a triple. For example, if an ontology uses dublin core properties without importing the corresponding namespace, then the system would suggest to import the DC namespace.

Parameters:

ontModel - the OntModel to analyze

Returns:

a Set of URI objects (often empty)

removeImport

public static void removeImport(java.net.URI importedURI,
                                boolean removeUsages,
                                org.eclipse.core.runtime.IProgressMonitor monitor)
