The CIARD RING exposes a simple REST API to get metadata about the datasets. It allows you to apply several filters so that you get only the results you need.
The API has two methods:
http://ring.ciard.info/api/ws-datasets? (returning literal value)
- http://ring.ciard.info/api/ws-uridataset? (returning URIs)
The two methods accept the same paramaters and return the same records in XML; the only differences between the two methods is that the response returned by the first one contains literal values in the XML elements, while the response of the second one contains URIs whenever possible as values of the XML elements.
