Field Summary

static SesameValueHelper	INSTANCE singleton instance.
static int	MILLISECONDS_PER_MINUTE number of milliseconds per minute, used to convert java.util timezone offsets to XMLGregorianCalendar timezone offsets.

SesameValueHelper()

Method Summary

org.openrdf.model.Literal	createLiteral(RepositoryConnection connection, Literal literal) create a Sesame literal from a SMILA literal.
URI	createUri(RepositoryConnection connection, Literal uri) resolve namespace prefixes in URI literal.
URI	createUri(RepositoryConnection connection, java.lang.String uriString) resolve namespace prefixes in URI string.
Value	createValue(RepositoryConnection connection, Literal literal) create a Sesame value from a SMILA literal: If semantic type of SMILA literal is set to "rdfs:Resource", known namespace prefixes are expanded and Sesame URI is return, else a Sesame literal with a matching datatype is created.
