The present disclosure is concerned with generating a unique representation of a physical asset from a plurality of datasets representing information relating to the physical asset. Each dataset is generated by a system that acquires the dataset in a system-specific format. Each dataset that includes information about the attributes of a physical asset is mapped to a corresponding system-specific global dataset, based on a global data model. The global system-specific datasets generated are merged together to generate a global dataset, based on the global data model. The global dataset therefore uniquely represents the physical asset.
