This document discusses the Linked Data Platform (LDP) and how following W3C recommendations can help organizations publish and maintain data in a more efficient way. It provides an overview of key W3C standards like RDF and the LDP. The LDP allows data to be accessed, updated, created and deleted using HTTP requests. Adopting LDP processes like producing data in RDF and publishing it online can streamline data maintenance versus traditional methods that require data to be exported in multiple formats and sent to others. The presentation argues LDP can reduce organizations' data publishing and updating workloads.
