A crowd sourcing project that uses the same infrastructure as the ‘London Street Views’ website, ‘Tag London’ asks schools to collaborate with the museum to help augment their data by identifying objects. After sign in, each user in a class is shown a stream of objects and asked to identify the period and type for each from the available list. The answers are then aggregated and the top scoring answer deemed correct. The whole process was gamified with each user being scored for accuracy and amounts, as well as a whole class aggregated score. The resulting metadata will be analysed by the Museum.
