At a recent research data management meeting in Essen, I asked the representatives of half a dozen German universities who use OMERO for their top priority from the various OMERO wish lists they had brought and offered to write it up. This is what they chose.
Users are unaware that after “copying” an image into another dataset that a delete of that image doesn’t delete a copy but deletes the underlying image data.
- Copy a link
- Paste into another dataset
- Delete the “link”
- No images are present
Loss of data
Suggested partial fixes (possibly conflicting):
- Turn off the feature completely due to the danger
- Rename the functionality
- Change the icon to avoid the association with copy-n-paste
- Change the wording to “link to this object”
- Change the wording on delete “Delete all copies of this image and the original data” (Perhaps only when multiply linked)
- Detect multiply linked images on delete and offer “Unlink this image or delete the original data”
