Publishing on data.gov.uk - overview
There are two methods for adding datasets to data.gov.uk:
Using the dataset (web) form. It is a simple & manual process. However it is not suitable for INSPIRE/Location datasets. More:
Using a harvester. You store the dataset records on your own server and they are ‘harvested’ regularly into data.gov.uk. It requires some set-up, but it is ideal when there is already a published list of datasets on your site (or elsewhere). More:
Before this you need to register a user account on data.gov.uk and get approved as ‘editor’ or ‘admin’ for your publisher.
NB You can’t ‘upload data’ to data.gov.uk. The data (e.g. spreadsheet file) should be published / uploaded onto your organization’s website (which for central government is gov.uk) and then you add to data.gov.uk a ‘dataset’ (record) containing information about the data, including the link to it (e.g. download URL).
