Updated editorial guidelines
This week, the BBC Trust published updated editorial guidelines for BBC programme makers, producers and journalists.
For the first time, the public is being asked to comment on them in draft form before they are finalised. BBC staff will also be consulted, by our Editorial Policy department, on their attitudes to the new draft.
One of the issues they cover, picked up by the Guardian's James Robinson, is writing for the web.
The new draft, also for the first time, fully integrates the original editorial guidelines and the (formerly separate) ones for Online.
The new guidelines state that nothing should be written online that would not be said on air:
It's perhaps worth explaining that it is already the case that all output, whether in text, audio or video, must comply with the BBC's existing editorial guidelines.
The first page of the existing guidelines says:
So the new guidelines are really spelling out, in the impartiality section, a principle which has long been enshrined in the BBC's editorial code.
As far as blogging goes, as we've launched each new reporter's blog on the BBC News site over the past few years, we've positively encouraged new recruits to the blogs to write informally, to respond to comments and just generally be themselves.
But we've also stressed that there's still a framework of editorial standards they must work within.
Sometimes we point out it's not much different from a "two-way", a broadcast interview with the reporter, where they answer a few questions from the studio to convey the latest on a story, and their analysis. Think Radio 5 Live, or John Simpson being quizzed by Huw Edwards on the Ten O' Clock news.
This informality translates well to blogs - and indeed to Twitter (as Laura Kuenssberg has been proving in the past few weeks of reporting from the party conferences).
Our news blogs, like our online news stories, are checked by a second journalist before publication.
For Laura's Twitter reports, we've applied "live broadcast" principles - for live news broadcasting, the rule is that it is monitored by an editorial figure as it goes out, normal editorial rules apply, and any mistakes should be swiftly and openly corrected.
Going back to the new draft guidelines, it's also worth pointing out that the "not saying online what you wouldn't say on air" principle works equally the other way round.
When Nick Robinson in an inadvertent slip on air this week referred to David Cameron as the prime minister, he was able to flag the mistake and set things straight in his blog.
If you want to read through the guidelines yourself rather than relying on media reports, and if you want to say what you think about any aspect of them - they are here in full, with feedback form. And of course, you can comment below too.
