In December the W3C created the Data Activity as the new home for the Semantic Web and eGovernment activities with Phil Archer as its lead. The Data Activity has eight ongoing groups, which include two new ones: CSV on the Web and Data on the Web Best Practices.
Much has changed in the past 15 years when the term Semantic Web was introduced and researchers and developers have produced a large and mature collection of concepts, languages and technologies. The new, wider focus on exploiting this in support of open data and services is welcome. You can keep track of what the W3C Data Activity is doing on the new Data Activity Blog.
