RDFa and SVG Tiny (and the RDFa distiller)

Powdering logos (again)

Lot has happened with POWDER since, and most of what I wrote in that blog is now technically outdated:-( So here is the updated example.

Open data, you and me
Data portability and open data are hot topics these months. The multiplication of social network sites has increased the aggregation of these data in silos. The Semantic Web activity encourages to open your data with a new series of cute logo. Geographical data such as the Open Street Map initiative, government budget such as USA are the trend. But when it comes to our personal data, we need more granularity.
