Abstract: A computer-implemented system is configured to provide data processing services to an entity; the system includes: (i) a data-analysis environment, which includes or accesses a data store that stores data and meta-data for one or more data objects that represent a store of value (‘data objects’), such as data objects that are created by the entity; and (ii) an API layer that links the data-analysis environment to (a) a digital wallet publisher, and to (b) a service publisher that publishes data to, and receives data from, the data-analysis environment.
