[dspace-tech] JP2 questions

2022-04-23 Thread Chris Clawson
I am using DSpace 7.2, with the Mirador viewer and Cantaloupe. I am unable 
to get my first attempts to use JP2 (jpeg2000) to view anywhere. When 
uploading as a bitstream, DSpace complains "unknown format". I have 
produced these jp2 images from png using imagemagick. The resulting images 
view well using Irfanview. I also downloaded a sample JP2 file and got the 
same results.
Isn't JP2 enabled by default? How/where do I check? Suggestions for 
troubleshooting?
C.

[dspace-tech] Re: Moving Bitstreams to other Items?

2022-04-23 Thread Chris Clawson
Thanks for the answer. For now, it may be just safer to export AIPs and 
Community/Collection metadata, and then develop methods to build working 
directories offline for later import. Such exports will provide all the 
images and records of anything needed for future items and also make it 
possible to create a new CSV of obsolete items to delete later.

[dspace-tech] stack trace option

2022-04-23 Thread Jose Blanco
I noticed that when there is an error, the page displays the stack trace
option ("Show underlying error stack"). This is great in development, but
is there a way to turn this off in production?

Thanks!
-Jose

[dspace-tech] spam on forms.

2022-04-23 Thread Jose Blanco
This weekend we had an ip that was causing trouble by sending /feedback and
/request-item submissions.  Has anyone encountered this in dspace and found
a way to mitigate it?

Thank you!
-Jose
