Maven Repository Metadata Model

 This is strictly the model for Maven Repository Metadata, so really just plain objects.

 The metadata file name is:

 * <<<maven-metadata.xml>>> in a remote repository,

 * <<<maven-metadata-\<repo-id>.xml>>> in a local repository, for metadata from a repository with <<<repo-id>>> identifier.

 []

    /**
     * Merge a new metadata set into this piece of metadata.
     * TODO this should only be needed on the repository metadata {@link org.apache.maven.artifact.metadata.ArtifactMetadata}
     *
     * @param metadata the new metadata
     */
    void merge(ArtifactMetadata metadata);

    /**
     * Store the metadata in the local repository.

    }

    /**
     * Method write.
     *
     * @param writer   a writer object
     * @param metadata a Metadata object
     * @throws java.io.IOException java.io.IOException if any
     */
    public void write(Writer writer, Metadata metadata) throws java.io.IOException {
        try {
            delegate.write(writer, metadata.getDelegate());
        } catch (XMLStreamException e) {
            throw new IOException(e);
        }
