A data dependency path calculator for a semantic search engine is provided. A body of semantically related data is modeled according to a semantic data model. A user is presented a list of data elements from which they may select desired data elements. The system automatically calculates all of the possible paths through the database that may be used to retrieve meaningful data based on the selected data elements. The available data dependency paths are returned to the user for selection. The system further provides a type of data permission that allows restricted data elements to be used as a pass-through data element for relating, connecting and retrieving non-restricted data. Thus, a user can use restricted data to create data dependency paths to retrieve meaningful data.
