PUBLISHING LINKED DATA FROM RELATIONALDATABASESCONCLUSIONS 16/12/2011 Hackaton 2011. OSLUCA. 22 </li> <li> 23. Conclusions Web based on documents Web based on Data. Linked Data as a way for interchanging data between different datasets in the Web. RDF as a standard format to describe data. Main aim: Create new third-party applications using open linked data from LD systems. 16/12/2011 Hackaton 2011. OSLUCA. 23 </li> <li> 24.
