The software has been written using Java, the Eclipse IDE 2019-03 shell has been applied. 

The software requires a database, here xampp has been used. 
In XAMPP, serveral tables have to be generated: 
- elements -collecting product data: an internal number, a name, a description
- structure -collecting structure elements: an internal number, a name, a description
- relations - collecting relations of structure
These have to be set in advance by the user. 
- relations -these are the ones calculated by the tool and filled by the tool

The tool is launched from the ecplise environment, a user interface opens, an upload of data to be linked can be uploade by teh user. 

The code refers back to the apache Lucene database, the fuzzy search module needs to be downloaded.
