Abstract: Embodiments are directed to managing data using a network computers. A hierarchy model that includes edges that represent dependency relationships between fields may be generated. In response to a query for determining values of metadata associated with an anchor field performing further actions, including: traversing the hierarchy model upwards from the anchor field based on the query, and in response to visiting field nodes in the hierarchy model, collecting the values of the metadata that correspond to the visited field node and terminating the traversal based on a type of the query; in response to visiting a calculation node, terminating the traversal of the hierarchy model associated with the visited calculation node; and in response to visiting a flow node that is dependent on two or more other nodes, terminating the traversal of the hierarchy model. The collected metadata may be provided in a response to the query.
