New: the source code has been placed into the public domain and can be downloaded below. Please make sure you have read and agreed to the terms and conditions.
Change the directory to where you unpacked the zip file. Double click on the file demo.bat in Windows Explorer or type demo.bat on command prompt. A file chooser pops up in which you can select a model-management script to execute. Once the script terminates, the file chooser window is displayed again. The execution trace of a script (including possible errors and warnings) is printed in the command prompt window.
First, execute the script init.mm to initialize the schema files. A window will pop up that shows the input schemas and the mapping between them. Close the window to terminate the script.
Then, run propagate_rdb-xsd.mm or propagate_xsd-rdb.mm. Answer the question "Be verbose?" with "Yes" to walk through the scenarios step by step. In the verbose mode, the intermediate results of the scripts are shown in popup windows. When such a window is displayed, you may simply close it to proceed. However, the intermediate results can also be modified. Specifically, you may have to adjust the mapping suggestions generated automatically by the Match operator (look into the script files). How to edit the mappings is described in the GUI section below.
The reintegration scenario allows merging the changes to a relational or an XML schema that were done independently by two engineers or tools (scripts: reintegrate_rdb.mm and reintegrate_xsd.mm in directory reintegration). This scenario is described in the Web Semantics article cited below. In short, the additions and deletions done on both schemas are reconciled in the resulting schema.
The reintegration scenario is also available in a run-through and verbose version. You will need to adjust the mapping m1x_m2x between the new elements added to both schemas.
If a morphism is shown, the user interface is always in one of the two modes: (a) a single element is selected and all its correspondences are shown, or (b) no elements are selected and the correspondences between all elements are shown. To switch back and forth between these two modes simply click on the same element multiple times.
Once an element has been selected, you can hold the SHIFT key pressed and select/unselect matching elements on the other side using a mouse click. To delete all incident arcs for an element, press CTRL and click on the element.
General note: sometimes you may need to resize a popup window to make the scrollbars appear.
The source code of Rondo includes an implementation of the Similarity Flooding Algorithm, and is distributed under terms and conditions listed below.
In addition, you may want to download the file contrib.zip that contains a modified version of the RDF parser SiRPAC (under W3C license) and the sources of the AElfred2 XML Parser (an early version by David Brownell).
To recompile the sources, unpack the Rondo source code and contrib.zip into the same directory and run the script recompile.bat.
