If I want to add some metadata (or, to be more specific, a title) to the metadata of a page in the sitemap (a Sitemap::Resource), would this be the proper way to do it?
the_page.add_metadata({:page => {'title' => 'Lorem ipsum'}})
How long can I expect it to stay there? Is the page metadata recreated every time the page is accessed, or does it have longer life?
