From the World Wide Web Consortium Web Site:
The Data on the Web Best Practices Working Group has published a First Public Working Draft of Data on the Web Best Practices Use Cases & Requirements.
This document lists some use cases, compiled by the Data on the Web Best Practices Working Group, that represent scenarios of how data is commonly published on the Web and how it is used. This document also provides a set of requirements derived from these use cases that have been used to guide the development of the set of Data on the Web Best Practices and the development of two new vocabularies: Quality and Granularity Description Vocabulary and Data Usage Description Vocabulary.
From a W3C Blog Post:
The Data on the Web Best Practices WG is faced with a substantial challenge in assessing the scope of its work which could be vast. What problems should it prioritize and what level of advice is most appropriate for it to develop in order to fulfill the mission of fostering a vibrant and sustainable data ecosystem on the Web?
