About Quatro

The Quatro project rests on two foundation stones: policy and technology. Users, content providers, labelling scheme operators, eCommerce practitioners and relevant industry organisations have been consulted on what they wished to see the system achieve and how it fits in with current operations and practices. On the technology side, academics and engineers from different fields reviewed the existing standards and practices.

A combination of these two reviews lead to the definition of common platform to support the labels and metadata (RDF-CL)

As well as the platform definition, Quatro had three further outcomes:

The expression of partner labelling schemes using the new system

Tools for end users that provide a simple graphical interface for the metadata found. The presence of metadata being signalled by an icon that can be clicked for more information.

The establishment of a new paradigm in which websites can carry useful and trustworthy metadata that can be used in a variety of systems to make the web a safer place for everyone.
