US Patent 10296501 Lineage-based veracity for data repositories

Techniques for determining and representing the veracity of data stored in a data repository and results of queries directed to the stored data by utilizing information lineage that is indicative of the veracity of the stored data. For example, in one example, one or more data repositories are maintained. The one or more data repositories comprise metadata representative of the veracity of one or more data sets stored in the one or more data repositories. In response to a query to at least one data set of the one or more data sets stored in the one or more data repositories, a result of the query for the at least one data set is returned in combination with corresponding metadata representing the veracity of the at least one data set.
