Abstract
Managing lineage information includes processing a specification of a directed graph to associate nodes with information for processing requests for a representation of data lineage. The processing includes: identifying a first set of one or more nodes of the directed graph corresponding to normalizing data elements being stored in a data store and de-normalizing data elements being retrieved from the data store; and associating a first plurality of nodes connected to the first set of one or more nodes and a second plurality of nodes connected to the first set of one or more nodes with at least one tag identifier having a plurality of possible tag values, where the number of possible tag values is at least as large as the number of data elements being normalized, and where nodes representing different data elements in a de-normalized record are associated with different values of the tag identifier.
