Abstract
Inspired by the PREEvision tool of Vector Informatik GmbH Stuttgart, we have extended SDMLib with so-called Table Graphs. Table Graphs model the matches of graph rewrite rules as explicit graphs added to a given host graph. Table graphs allow to do relational operations like filter and projection. We also provide support for the extension of matches with new nodes or attribute values. Table Graphs also allow to do many spreadsheet like computations via simple graph rewrite rules. Finally, Table Graphs may be exported as HTML Tables or CSV files. This allows e.g. to generate a nice PIE chart from a graph query result.
