  2. LOD achievements and challenges • Web - a global, distributed platform for data, information and knowledge integration • exposing, sharing, and connecting pieces of data, information, and knowledge on the Semantic Web using URIs and RDF • Achievements Extension of the Web with a data commons (25B facts vibrant, global RTD community Industrial uptake begins (e.g. BBC, Thomson Reuters, Eli Lilly) Emerging governmental adoption in sight Establishing Linked Data as a deployment path for the Semantic Web. • Challenges • Coherence: Relatively few, expensively maintained links • Quality: partly low quality data and inconsistencies • Performance: Still substantial penalties comparedto relational • Data consumption: large-scale processing, schema mapping and data fusion still in its infancy • Usability: Establishing direct end-user tools and network effect April 2008 July 2007 September 2008 July 2009
