Method Detail

canonicalPrefix

public static String canonicalPrefix(String prefix)

Remove ":" from a prefix if necessary to make it canonical.

Parameters:

prefix -

Returns:

prefix, without colon.

canonicalGraphName

public static Node canonicalGraphName(Node graphName)

Canonical name for graphs

abbreviate

public static String abbreviate(PrefixMapI pmap,
                                String uriStr)

abbreviate a uriStr, giving a string as a short form. If not possible return null. This does not guarantee that the result is suitable for all RDF syntaxes. Further checking for the rules of a particular syntax are necessary.

abbrev

public static org.apache.jena.atlas.lib.Pair<String,String> abbrev(PrefixMapI prefixes,
                                                                   String uriStr)

Abbreviate a uriStr, return the prefix and local parts. This does not guarantee that the result is suitable for all RDF syntaxes.

expand

public static String expand(PrefixMapI prefixes,
                            String prefixedName)

Expand a prefixedName which must include a ':'

expand

public static String expand(PrefixMapI prefixes,
                            String prefix,
                            String localName)

Expand a prefix, local name pair.
