getDatatypeURIs

public static List<String> getDatatypeURIs()

Gets a List of all datatype URIs.

Returns:

a List the datatype URIs

isNumeric

public static boolean isNumeric(String datatypeURI)

Checks if a given URI is a numeric datatype URI.

Parameters:

datatypeURI - the URI of the datatype to test

Returns:

true if so

isSystemDatatype

public static boolean isSystemDatatype(org.apache.jena.rdf.model.RDFNode node)

Checks if a given RDFNode represents a system XSD datatype such as xsd:int. Note: this will not return true on user-defined datatypes or rdfs:Literal.

Parameters:

node - the node to test

Returns:

true if node is a datatype
