The Datahub provides free access to many of CKAN's core features, letting you search for data, register published datasets, create and manage groups of datasets, and get updates from datasets and groups you're interested in. You can use the web interface or, if you are a programmer needing to connect the Datahub with another app, the CKAN API.
In our experience, one of the most effective tactics for eliciting datasets for the collection is a simple librarian-researcher interview. In this poster, we share a set often questions that a librarian can use as a starting point for such a “data interview”. It is a practical tool to draw out information that needs to be considered in order to evaluate the suitability of a dataset for the collection and the requirements for the infrastructure and services that will be needed for data curation.
the Data Hub is a community-run catalogue of useful sets of data on the Internet. You can collect links here to data from around the web for yourself and others to use, or search for data that others have collected. Depending on the type of data (and its conditions of use), the Data Hub may also be able to store a copy of the data or host it in a database, and provide some basic visualisation tools. This site runs on the open-source data cataloguing software called CKAN, written and maintained by the Open Knowledge Foundation. Each 'dataset' record on CKAN contains a description of the data and other useful information, such as what formats it is available in, who owns it and whether it is freely available, and what subject areas the data is about. Other users can improve or add to this information (CKAN keeps a fully versioned history). CKAN powers a number of data catalogues on the Internet. The Data Hub is an openly editable open data catalogue in the style of Wikipedia.
