The invention discloses an apparatus and a method for identifying nodes in a node-based data source, the apparatus being unique node identifiers, or series of unique node identifiers. The identifiers remain unchanged despite transformations of the data source. Any modification made to data derived from the transformations is also effected at the data source by means of the identifiers, the identifiers mapping the data in the transformed version of the data source to the data in the data source. |
