In Material Flows: remove option to "automatically extract compressed files" when the Content Structure is changed to METS
The material flow configuration includes the default option to "automatically extract compressed files". This option works in all workflows except METS content structure work flows, as extracting compressed files leads to mismatches in the METS struct map.
Material flow configuration screens should blend out the extraction option for METS content structure or make the user aware of a faulty configuration upon saving such a combination.

Yes, our "ideal" scenario was also that extraction worked in METS deposit worfklows. The path towards discovering that the extract funtionality didn't work in this case was a painful one ;-)
We value the flexibility benefits of the METS deposit such as multi-rep and pre-ingest fixitiy values etc., but also frequently have deposits including zip packages. I'm wondering - would you see the extraction as a permanent action, meaning that an exported AIP would contain the extracted files? Or as a temporary measurement within the archive, where an export would have to include the zip container?

We too had to accept the fact that the option "automatically extract compressed files" does not work with a METS content structure material flow. However, we would come to a different conclusion: Our wish would be not that this option be removed, but that it actually worked! We are looking for a way to extract zip or tar files during automatic ingest from our research data repository to Rosetta, because we would prefer to archive single files rather than zip or tar containers.
We are of course well aware of the fact that this is rather a dream than a realistic expectation. In order to avoid the mismatch between the original METS structmap and the new file structure, there would probably have to be some transformation process in between.
