Goals• A solution to solve free-tagging issues (ambiguity,

heterogeneity, lack of orgnisation)

• An ontology to represent global and local meaning of tags in a machine-understandable way, using URIs of LOD resources

• A framework to assign and share meanings to tags in a collaborative and open way

• A process to create Linked Data from simple tagging actions
