Hi George,

Did the bitstream_format_id get changed to the "Unknown" type, or is it still 
the original ID?

If it's still the original ID, I would go into the database table 
bitstreamformatregistry and change the ID of the new record to the old ID.  
Then, of course, revert the ID of those few records you updated to the new ID.

If it's not, I'd probably run a SQL query:  "update bitstream set 
bitstream_format_id = [NEW_ID] where bitstream_format_id = [OLD_ID]"

And for sure, make a backup of the db before trying either of these.

B--

Subject: [Dspace-tech] Question about bitstream format registry

Hi...

I discovered today that I had a bitstream that was dropped from the bitstream 
format registry (my fault) when I went from DSpace 1.7.1 to DSpace 1.8.2, so 
every item using the specific bitstream now shows it as "unknown".

I fixed things in the bitstream registry and fixed a few records by typing in 
the correct ID number while the item is in "Edit" Mode, but I have 226 items to 
be updated.

I was wondering if I did an index update would that automatically fix the 
bitstreams to show that they are now known or is there some batch way to 
updated the display of these bitstreams?
