  Parameters:
    `resource` - The resource
    `writer` - The rdfwriter
  Throws:
    `IOException`

### insertIDOrAboutAttribute

    public static void insertIDOrAboutAttribute(RDFResource resource,

                                         throws IOException

  Inserts an rdf:ID attribute for the specified resource. If the resource is in the rdfwriter's default namespace then the local name is used. If the resource is not in the rdfwriter's default namespace then the full resource URI is used.

  Parameters:
    `resource` - The resource
    `writer` - The rdfwriter
  Throws:
    `IOException`

### insertResourceAttribute

    public static void insertResourceAttribute(RDFResource resource,
                                               XMLWriter writer)
                                        throws IOException

  Inserts an rdf:resource attribute for the specified resource. If the resource is in the rdfwriter's default namespace then the attribute value will be a # with the local name concatenated. If the resource is not in the rdfwriter's default namespace then the attribute value will be the full resource URI.

  Parameters:
    `resource` - The resource
    `writer` - The rdfwriter
  Throws:
    `IOException`

### getResourceAttributeName

    public static String getResourceAttributeName(RDFResource resource,
                                                  XMLWriter writer)

  Gets the value for a resource attribute value such as rdf:about or rdf:resource. If possible, the resource name is written as a relative URI that is resolved against the xml:base of the document.

  Parameters:
    `resource` - The resource

### insertResourceAsElement

    public static void insertResourceAsElement(RDFResource resource,
                                               XMLWriter writer)
                                        throws IOException

  Creates a new element, with a tag name that reflects the default namespace of the `XMLWriter`

  Parameters:
    `resource` - The resource to be inserted as an element.
    `writer` - The `XML` rdfwriter that the element will be written to.
  Throws:
    `IOException`

### isInDefaultNamespace

    public static boolean isInDefaultNamespace(RDFResource resource,
                                               XMLWriter writer)

  Checks whether a resource is in the default namespace for an `XMLWriter`

  Parameters:
    `resource` - The resource to be checked.
    `writer` - The `XMLWriter` that the resource's namespace should be checked against.
  Returns:
    `true` if the resource is in the rdfwriter's default namespace or `false` if the resource is not in the rdfwriter's default namespace.

### getNamespacePrefixes

    public static XMLWriterNamespaceManager getNamespacePrefixes(NamespaceManager nsm,
                                                                 String defaultNamespace)

  Gets the namespace prefixes for the combination of a `NamespaceManager` and `XMLWriter`. The default namespace for the rdfwriter may not be the same as the default namespace in the namespace manager, so the result of this method does not include the prefix for the default namespace in the rdfwriter.

  Parameters:
    `nsm` - The `NamspaceManager`
    `defaultNamespace` - The default namespace
  Returns:
    A `Map` of `String` pairs. The keyset contains the prefixes.

### renderTypes

    public static void renderTypes(RDFResource resource,
                                   TripleStore tripleStore,
                                   RDFResource excludeType,
                                   XMLWriter writer)
                            throws IOException

  Renders the types for a resource as rdf:type triples.

  Parameters:
    `resource` - The resource whose rdf:type triples are to be rendered.
    `tripleStore` - The triple store that the renderer should render with respect to - only type triples that are asserted in this triple store will be rendered.
    `excludeType` - The one type that should not be rendered - this method expects that this type will have been used in the RDF/XML optimisation practice of putting one of the types as an element tag name.
    `writer` - The `XMLWriter` that the triples will be added to.
  Throws:
    `IOException`

### getType

    public static RDFResource getType(RDFResource resource,
                                      TripleStore ts)

### getOntologyName

    public static String getOntologyName(OWLModel model,
                                         TripleStore tripleStore)

### getPrefixedName

    public static String getPrefixedName(String fullName,
                                         TripleStore tripleStore)
