Honest John: The MoT Files: The Story Behind The Data

Good case study on FoI, open data and the how cleaning data is always the first, and often most valuable, step in the data journalism process: "Following the launch of the OpenData website ... we downloaded the MoT data when it became available and set about getting it into a format that could be easily accessed. With more than 355m records, 200m MoTs (all those since the system was computerised in 2006) and 40gb of data, this wasn't an easy task. Like the BBC, we have also had a few problems dealing with the MoT data that's provided by the Government. Firstly, it's huge and difficult to work with. Secondly, as it's sourced from thousands of technicians - and humans make mistakes - it was littered with errors. There were plenty of cars registered in the 1800s and a few steam-powered Renault Clios to boot. We've done our best to ensure it's as clean as possible, but with such a huge data set, there may still be the odd error."

Paul Bradshaw: The investigated ‘investigate’: Primark does Panorama

"The [Primarl] video borrows all the language of investigative journalism (if not Panorama's production values) to 'follow the trail' of the investigation's producer in making the programme - before lapsing into promotional video mode at the end when it talks about Primark's code of conduct and shows its products. ... Apart from the commercial implications of advertisers spending their money on communicating directly with customers, there is an editorial consideration here: any publishing strategy needs to account for this sort of reaction. The more evidence you can publish online, the better."

PR Week: Primark accuses Panorama of ‘deceiving millions’ following BBC Trust findings

"Primark’s response to the BBC Trust’s findings has been packaged up on a microsite, which includes the statement along with a video explaining Primark’s case and a timeline of events. Primark’s long-standing retained agency Citigate Dewe Rogerson was issuing links to this microsite to the media yesterday."

BBC News: Local spending survey blocked by government

"The BBC's attempts to collate this spending data largely avoided some obstacles placed in the way of alternative research being carried out by other media. ... Local Government Chronicle (LGC) was pursuing a similar survey. But it appears to have asked for what's called Revenue Account information ... DCLG instructed councils not to provide this data, on the grounds that it is intended for future publication by the Office for National Statistics."
