"Part of our long term vision for the ecosysem of open data is one in which we can work with large datasets in increasingly automated ways. Hence we are pleased to announce the release of v.0.5 of Datapkg, a user tool for distributing, discovering and installing data (and content). This is a key part of making data sharing automatable.
By packaging the data its metadata becomes standardised and can be placed within a repository, such as CKAN, whereby it becomes significantly easier to find, retrieve and use: as an end-user tool it allows automated (command-line or scripted) discovery, installation and sharing of data “packages” either standalone or via interaction with a registry like CKAN."
