There are, for example, class articles, copies of which are kept in Google release date storage. And I want to give a link to it:
[ a href="/article/{{ article.uid }}" ]
To make like this:
[ a href="/article/55" ]
Google has its UUID's, but they are a bit too scary for to be part of the url: ahBzb3ZpZXRncm9vdmVibG9ncg0LEgdBcnrpy2xlgagm.
