ckanext-dara

CKAN extension that integrates the da|ra metadata schema and enables registration of DOIs at da|ra. It has been developed for the EDaWaX project at the ZBW (German National Library of Economics) and is now actively used for the CKAN based RDM platform ZBW Journal Data Archive.

General

CKAN offers only a kind of general and limited set of metadata for datasets (like title, description, author), that does not reflect any common schema. You can, nevertheless, add arbitrary fields via the webinterface for each dataset. But that’s not schema based. The approach of CKAN here is to avoid extensive metadata forms, that might restrict the usability of the portal, and also not to specialise on certain types or categories of data, like, you name it, research data. Dedicated research data applications like Dataverse do have an advantage here. Dataverse’s metadata forms are based on the well-known and very extensive DDI schema. CKAN is not originally a research data management tool, and the lack of decent metadata schema support is one point where this hurts. However, this more general approach as well as the plugin infrastructure enables us to customise the dataset forms, add specific (meta‑)data, and to guarantee compatibility with a given schema. ckanext-dara does that for the da|ra metadata schema.

ckanext-dara has been developed with two principles in mind:

1. make metadata input and DOI registration as easy as possible
   The ZBW Journal Data Archive is intended for editors and authors of scientific journals, who like to publish the research data on which their article is based. Those persons neither have time nor motivation to fill in 100+ metadata fields before they can upload their data. `
