I think it is a bad idea to create any filename in a DCP without a UUID.

During a certain time in digital cinema history, many things were possible and common in DCPs, and sometimes, when looking at todays raw DCP files, I miss revealing file names for metadata, assets and KDMs. But I think the use of UUID is a must for reasons of file consistency.

While there are some filename length limitations to keep in mind, I think the best idea is to enable another placeholder in advanced prefs - metadata file name format to include the shortened CPL title together with a UUID. Maybe %c (compliant with asset filename format). Or %d ('DCP name') (%n for 'name' and %t for 'title' is already taken for number of reels and asset type and could be confusing).

Occasionally, I see UUIDs for package/DCP names on servers. Usually they reveal that users did not understand the difference or used their software with some standard settings.

I think, in this example the reason is that no annotation text is set in the PKL file, so, our Sony shows only the PKL UUID. Other servers may handle this in a different way. Some servers may go for PKL/Package, some browse for CPLs. There is no actual standard on how servers display content for ingest or playout.
