Managing lineage information includes processing a request for a representation of data lineage for a first node of a number of nodes. The processing includes determining an association between the first node and at least a first tag identifier of a number of tag identifiers, and determining a first subset of at least one and fewer than all of a number of possible tag values for the first tag identifier, and traversing nodes along a first lineage path of directed links from the first node to determine a data lineage for the first node. Determining the data lineage includes, for each traversed node determining whether to add the traversed node to the data lineage or to exclude the traversed node from the data lineage based at least in part on any tag identifiers or tag values associated with the traversed node.
