QUATRO (The Quality Assurance and Content Description project) has built a common platform to enable all types of labelling systems to be machine-readable, providing end users with the ability to check that the label is trustworthy and that certain criteria are met. Quality labels, also called trustmarks, can be used for any type of digital content and therefore on a variety of devices, the two most common applications being websites and mobile phones. The platform will enable end users to see whether a label is still valid, and that the information can be trusted.
Quatro uses RDF (Resource Description Framework) technology and the project has developed three demonstrators which include:
- a proxy server, which reads and communicates label information.
- (Visual interface for Quatro) a browser extension which displays the quality label information to the end user.
- (Label Display Interface) is a search engine results wrapper which annotates the results with label icons.
Labelling authorities using Quatro include:
- The Web's leading labelling organisation for child protection
- the Internet Quality Agency: A quality seal covering legality, honour, responsibility, confidentiality, protection of human dignity, protection of minors, protection of public order, protection of private lives.
- Web Mèdica Acreditada: certification for the accuracy and validity of health-related information online.
The two year project aims to extend the scope of the Quatro platform to include user-generated labels as well as improve the performance of the existing tools and provide new simple tools for label creation.
Additionally, Quatro Plus will promote the benefit of authenticated machine-readable labels to a variety of commercial interests across Europe such as existing and potential trustmark operators, awards bodies, portals, search engines, users etc.
MDR Partners is responsible for co-ordinating Quatro Plus and adding expertise in the libraries and public sector to the project.
