These are requests for particular government dataset to be made public (and ideally open). The requests are added by anyone, using a form at data.gov.uk and they are listed at https://data.gov.uk/data-request
Only 'public' data requests are included in the data published here. Confidential requests can also be made, e.g. for commercial confidentiality. There is a count of them provided on https://data.gov.uk/data-request which at the time of writing stands at 522 confidential requests out of 1257 dataset requests.
There are two versions of the data:
v1 - missing a couple of fields. Live data (always up to date).
v2 - contains all the public fields. Produced nightly. System fields: nid, url, created, updated. Requester fields: title submittedby datathemes status description suggesteduse suggestedusedetail benefitsoverview. Government response: publisher datasetlink fieldreview_notes.
Policy for requests:
a "data request" is a request for government to publish a dataset that is not yet published on data.gov.uk. Requests associated with specific datasets already on data.gov.uk should instead be made in a comment on the particular dataset page.
only central government and its agencies are available in these requests. For others organizations, contact them directly and consider making an FOI request.
your personal data should not be requested with this method - contact the relevant organization directly.
each request will be directed to the relevant department by the Cabinet Office team.
(These have been shown on the form since late 2015, and before that the policy varied)
Data requests on file date back to September 2012.
