Data.gov.uk goes public today, and we’ve very proud that it is using CKAN, our open source registry of open data, to list official UK government datasets (as we announced in October):
We’ve been working closely with the Cabinet Office team to get this out the door, and over 2500 datasets have been released via the site!
In the Cabinet Office press release, Sir Tim Berners-Lee says:
Making public data available for re-use is about increasing accountability and transparency and letting people create new, innovative ways of using it. Government data should be a public resource. By releasing it, we can unlock new ideas for delivering public services, help communities and society work better, and let talented entrepreneurs and engineers create new businesses and services.
The new launch has received lots of press coverage – even making the front page of the BBC news website! Below is a selection:

This is great news. I was wondering has anything been written up about how you are doing the technical integration between data.gov.uk and ckan.net? I’m curious if you are dumping the data, or if some sort of web apis, feeds, etc are being used.
Hi Ed,
Expect linking up of the two sites soon, now that data.gov.uk is public.
If you’re looking to get hold of a dump of all the government metadata then we’re distributing it at http://ckan.net/dump/
David Read, OKFN
Do you have a list of which data sets of the 2500 are new releases of information, and which are data that has been / would have been published anyway?
It’s really great to have a directory of all the data, and I hope it starts populating search results so people can find data more easily.
But quite a lot of he 2500 seem to be ONS data sets which have been around for a while. I’d like to pick apart the new data that might be of a different nature!

@Ed to follow up David’s comment: in the current set up, data.gov.uk is talking to a CKAN instance using CKAN’s API
@Francis: this is a really good question – and one we don’t know the exact answer to! While we’ve been working with the data.gov.uk team to get datasets into the data.gov.uk CKAN instance, given the pace of work, we ourselves haven’t been able to look through the datasets in detail yet! Some datasets that I’m certain are newly available (or at least in the form found there) include the traffic count material and the edubase DB.
@Rufus interesting, so if an instance of ckan is running at data.gov.uk does that mean the ckan api is available there as well?

@Ed, Metin2: the basic answer is currently no as the RESTful JSON API on the CKAN backend is not being exposed by the data.gov.uk frontend. However, there are plans afoot to a) expose the API on the frontend b) sync all the dataset info from data.gov.uk onto ckan.net where you will be able to get at it with the ckan.net API.
In the mean time, if you’d be willing to get the data in bulk there’s a nightly dump of all data.gov.uk packages/datasets at http://ckan.net/dump/
@metin2hileleri interesting, so if an instance of ckan is running at data.gov.uk does that mean the ckan api is available there as metin 2 the?
Wow just seen this and thought wow you let the UK government use your opensource software! Surely they would have over paid you for it like they would do for most things? Sadly the property prices are not being released
But quite a lot of he 2500 seem to be ONS data sets which have been around for a while. I’d like to pick apart the new data that might be of a different nature!
opensource will power the world one day
Good job on getting the government on board
opensource is the way forward so many implementaions accurate discisions
very nice application, I support the government’s transparent application.

The UK government seems to be quite progressive in the OpenSource, Crowdsourcing, Altruism etc arena – I read the New Scientist and it must be about every two issues you read something by the UK governement (directly or funded by) launching an open data set, or collaboration initiative.
Makes up for some of the crap things they’re doing!
Well done you guys
