CKAN's QA extension just got better

Last month CKAN's QA extension went live on the datahub. At the time, QA metrics and information were only displayed on the QA page, but Ian has been working on it and it's now beautifully integrated with the web interface, with each dataset page graphically showing the star rating for each resource, as in the screenshot below: [caption id="" align="alignnone" width="640"][Screenshot: QA extension in CKAN UI] Dataset view showing the openness stars[/caption]The star-rating shown is calculated according to Tim Berners-Lee's 5 Stars of Openness, and by hovering your mouse over it, you can see what the stars earned are for, and which ones are still to come. The extension runs automatically in the background and calculates the star-rating as documented on the CKAN wiki. At present it can still only calculate the first 4 stars (out of 5); there's a proposal for calculating the fifth star (details are in this ticket on the tracking system).
