represents an URI node that may occur in a RDF graph.
Description
marks an object representing an ODF element that may have RDF meta data
attached.
To make using ODF elements as part of RDF statements more convenient,
this interface inherits from XURI.
The URI is constructed by concatenating the URI of the document, the
stream name, a fragment separator, and the XML ID.
Note that using the XURI interface on an instance of
XMetadatable may have the side effect of creating a metadata
reference for the instance.
creates a metadata reference for this object, if necessary.
If this object already has a metadata reference, do nothing;
otherwise, create metadata reference with a fresh, unique XML ID
and assign it to the MetadataReference attribute.
a metadata reference, comprising the stream name and the XML ID.
Note that this metadata reference must be unique for the ODF document.
This implies that the XML ID part must be unique for every stream.
A pair of two empty strings signifies "no metadata reference".
For example: Pair("content.xml", "foo-element-1")
Throws
com::sun::star::lang::IllegalArgumentException
if the given metadata reference is invalid, or not unique
