The problem

• Sorting the wheat from the chaff
• The "good" from the "bad"
• The exceptional from the mundane
• The real data from the scam

Quality and Content Description

• Labels - covered in other workshops and events
• Now being refined in Content Label Incubator Activity (WCL-XG)
• Concentrate today on assessing the trustworthiness of a label (metadata)

The Web is replete with trustmarks

Trustmarks

Much in common, for example:

• Is the creator of the website clear and honest
• Is the domain name transparent
• What are the content provider credentials (esp. Medical/Scientific sites)

The Quatro Vocabulary

Four sections

• General Criteria
• Criteria for labelling to ensure accuracy of information
• Criteria for labelling to ensure compliance with rules and legislation for e-business
• Terms used in operating the trust mark scheme itself

Published in text form and as an RDF Schema

Quatro allows a TM operator to:

• Offer machine-readable/machine discoverable trustmark
• Use common vocabulary for common elements of a TMS - facilitating interoperability
