DESCRIPTION
A presentation at the workshop "Rich and loonely or poor and popular?" at the Dublin Core conference in Lisbon on September 4th, 2013. The main hypothesis is that when publishing (linked) data, the main criteria should not be richness and poorness, but suitability for purpose, granularity and adherence to agreed-on models.
