Abstract: A declarative specification of a search pattern for a graph visual programming language code is received. A repository of graph based visual programming language code instances is analyzed using one or more processors to identify at least a portion of a visual programming language code instance of the repository that matches the search pattern. An indication of at least the portion of the visual programming language code instance of the repository that matches the search pattern is provided.

Abstract: The invention relates to a conductor track layer structure precursor stage with conductor tracks, which are disposed on an electrically insulating substrate with an inner region and a lateral peripheral region and which are connected via conductor track current lines to at least one current line which extends in the lateral peripheral region. Per conductor track, there is one conductor track current line. The conductor tracks are electrically insulated from one another within the inner region of the conductor track layer structure precursor stage. The invention also relates to a conductor track layer structure which can be obtained from the conductor track layer structure precursor stage.
