Our content model relies on tags... ...which are not anywhere near as boring as you think Keywords Contributor Series Publication Tone Article Video Audio Gallery Cartoon Tags Content Keywords

3.
Every piece of content carries a selection of hand-picked tags

4.
They are added during content production ...and the system suggests them as you type

5.
There is also a tag browser in the CMS

6.
And a search so that you can 'Batch Tag'

7.
There is an admin interface to manage tags...

8.
...and generate reports on what has been created

9.
On the site they give us related links & tag pages (OK, that is admittedly a little bit boring)

10.
They allow us to cross-promote content A film review for "The Damned United" is in amongst the football stories

11.
And we can create 'combiner' pages with them...

12.
...many of which are more useful than bullfighting+vuvuzelas This page is assembled automatically by combining the 'review' tone with the 'books' section

13.
Tags are used to place editorial components Stories tagged with 'Apple' in the Technology section display recent tweets on the topic by Guardian contributors

14.
And to customise commercial components Adverts that appear in the Guardian Jobs slot are tuned by the tags applied to article content

15.
Topical navigation on the iPhone The Guardian iPhone app uses tags to provide lateral navigation into topics

17.
Trending on the iPhone The iPhone app also examines the tags with the most activity, to produce the 'trending' topic index

18.
Tags help with search results We use links to tag pages as results for synonyms and near-synonyms commonly used by readers

19.
Tags can go in folders ...and we can turn those folders into A-Z lists and navigation on the website

20.
And our tags are on Twitter To our knowledge, they are the only bit of our information architecture to have an official presence on Twitter

21.
Now our tags are entering the world of linked data

22.
Our book reviews carry ISBNs

23.
And our content API can be queried by ISBN http://explorer.content.guardianapis.com/

24.
Our artist tag pages have MusicBrainz IDs associated with them

25.
And the API can be queried by MusicBrainz ID

26.
Why XML and JSON? And not something a little more rich and semantic?

27.
Where do we go next? Where can we get the most linked data for the least effort? What will be used in the real world?
