Add ability to rename bitstreams (filenames) in XMLUI
-----------------------------------------------------
Key: DS-862
URL: https://jira.duraspace.org/browse/DS-862
Project: DSpace
Issue Type: Improvement
Components: XMLUI
Affects Versions: 1.7.1, 1.7.0, 1.6.2, 1.6.1, 1.6.0, 1.5.2, 1.5.1, 1.5.0
Reporter: Kim Shepherd
Assignee: Kim Shepherd
Fix For: 1.8.0
Add ability to edit a bitstream's filename as well as description, format, etc.
in XMLUI's EditBitstream form.
This is a trivial change and helps keep parity with JSPUI. There are
implications to renaming bitstreams -- none severe, but worth considering.
1. Bitstream links are usually displayed with the filename included.
Since handle and sequence ID are what actually matches the request to the
item+bitstream, this is not a problem. Old/cached/indexed links will still work.
For this reason, editing bitstream filename in the EditBitstream form is
actually safer than deleting and re-uploading the bitstream, which would
generate a new sequence ID and cause old links to be unusable (a lot of
repository managers use this as a workaround currently)
2. Bitstreams derived from filter-media processes (eg. THUMBNAIL/image.jpg.jpg
and TEXT/document.txt.txt) will, in practice, become orphaned, and on the next
filter-media run, the derived bitstreams will be regenerated and added to the
TEXT, THUMBNAIL. etc. bundles. This is potentially a problem, in terms of
storage space, search term boosting, thumbnail duplication could affect display
of item lists, and so on.
It could be possible to programatically search for the derived bitstreams (eg.
search for oldname.*.txt) and rename to fit the renaming of the ORIGINAL
bitstream, but my opinion is that this is something that should be left up to
repository managers/administrators, and that as long as we clearly document a
recommended renaming procedure (we could even display a javascript warning
alert or something, if necessary), the "human touch" will always be better than
the interface trying to guess what other bitstreams to touch.
Attaching patch that's tested internally at my institution, but will not commit
until vote at dev meeting has been taken and others have had a chance to
comment.
