This depends on your ingestion process. Usually the unique ids that are not filenames may come not from a file or your ingestion process does not tel the file name. In this case the Collection seems to be configured to generate a unique identifier.
Maybe you can describe more in detail on how you process the files. A wild speculation could be that they come from inside a zip file. In this case Metadata from Tika could be used as an Id were you concatenation zip file + file inside zip file . However we don’t know what you have defined how your ingestion process looks like so this is pure speculation from my side. > Am 18.12.2019 um 16:40 schrieb Nan Yu <n...@z-geoinfo.com>: > > Sorry that I just found out that the mailing list takes plain text and my > previous post looks really messy.
