Will this appendix be updated with better specifications of the allowed file formats at some point?
For the more complex formats, such as video it has been somewhat of a hit and miss whether the IMDI-specification will allow a certain file or not.
In the video section of the supported file types list only containers are listed, which is not sufficient. I know from first hand experience that not all mpeg2 files will be allowed, depending on how they were encoded (mpeg is as far as I know unfortunately both the name of a codec and the container).
Most video containers allow for several variations of the audio and video stream etc. If I remember correctly, the problem when trying to upload mpeg seemed to be the audio stream - mp3 audio would not work whereas mp2 worked fine and mp3 is the more efficient of the two.
Since the supported file check in LAMUS is done after the upload process is done (or test-linked in Arbil) it can be a somewhat frustrating situation turning into trial and error with smaller test files for larger batches.
What does “not accepted for new data, tolerated for legacy data for the moment” in the list mean for the end user or a data manager, by the way? That MPI might not accept these files if deposited whereas external projects using their own corpus server with MPI software could opt to accept them by overriding server settings? (sorry, this should probably have been asked in the LAMUS forum)
