What the Adoption of schema.org Tells About Linked Open Data
Heiko Paulheim · MADOC (University of Mannheim) · 2015
schema.org is a common data markup schema, pushed by large search engine providers such as Google, Yahoo!, and Bing.To date, a few hundred thousand web site providers adopt schema.organnotations embedded in their web pages via Microdata.While Microdata and Linked Open Data are not 100% the same, there are some commonalities which make a joint analysis of the two valuable and reasonable.Profiling this data reveals interesting insights in the ways a schema is used (and also misused) on a large scale.Furthermore, adding a temporal dimension to the analysis can make the interaction between the adoption and the evolution of the standard visible.In this paper, we discuss our group's efforts to profile the corpus of deployed schema.orgdata, and suggest which lessons learned from that endeavour can be transferred to the Linked Open Data community.
