Currently we are implementing BMEcat ETIM 4.0 support in our software DataProcessor TJ. Of sure we can export files with this ETIM 4.0 version, but we also want to test manufacturer files which are not generated with our own software. This way we can see if importing these random files perfom well. 
We found out there are still a lot of files around which are not 100% according the guidelines. When someone has example files we can see if we can improve our validation, of course keeping in mind that only correct data shall be imported in the end.
If you have sample data for me, please leave a reply! Thanks in advance ?
