…whose structure we worked hard to get right as part of the project. This was an important part of weaving ourselves into the fabric of the web: to ensure our referencing system had a useful structure to those outside our organisation.

Previously our URLs looked like this:

http://politics.guardian.co.uk/tonyblair/story/0,,2075005,00.html

today the same piece of content is referenced like this:

http://www.guardian.co.uk/politics/2007/may/10/tonyblair.labour3

There are two obvious changes here. First, the obscure numbers have gone — a legacy of our old Vignette StoryServer software, and utterly useless to anyone who happens to be a human being. Second, we’ve included the date in a friendly format, to provide some sense of orientation, and particularly useful if you happen to be looking at several URLs at a time.

There are other changes, too. The “politics” reference has come out of the domain name and into the path, to reflect the fact that all our content is part of the guardian.co.uk site. A couple of keywords also appear in the URL, partly to convey what the content is about, and partly to distinguish it from any other content that appeared in the same section on the same day. As it happens, quite a lot was written about Tony Blair and Labour on that day, so the “3” adds a further unique identifier.

In some ways URL structure is an obscure topic, but getting it right opens up access to more of our content in more ways to more people. Further examples have been given by Matt McAlister in his discussion of the RSS feeds.
