Published Data Library (PDL)

Dataset modification and versioning

The fundamental principle of the PDL is that datasets are stored unchanged for an indefinite period. Should changes to a dataset be required then this will be implemented by publishing a new version of the dataset, which will involve the following

The one exception, to cater for data sets that acquire new data whilst the existing data remain unchanged, is the ability to 'grow' a DOI. In this case it is permissible to add data files and documentation to an existing published data set under the existing DOI as long as the original data files and documents remain totally unchanged.
