The CIARD RING

The CIARD RING (a Routemap to Information Nodes and Gateways) is a registry of information sources/services in agriculture.
The services registered in the RING are described in details and categorized according to criteria that are relevant to the use of the service and its interoperability (such as standards adopted, vocabulary used, technology used, protocols implemented, level of interoperability etc.). In addition, the RING features detailed instructions on how the registered services can be "interoperated".
The RING is a CIARD project led by GFAR and is available at: http://ring.ciard.net
