[Fez-users] fez creating datastream names too long and not saving attached file descriptions

[Frederick D. S. <ri...@co...>]

After a few successful editing and reindexing of any given object, a
difficulty has begun to occur, when again saving and in reindexing these Fez
Fedora objects.  After 3 or 4 editings or reindexing of any objects, their
datastream IDs and corresponding file names grow by prepending and embedding
the preservation metadata prefix 'presmd_' multiple times for successive
edits, to such extent that errors result because IDs and names are too long
and therefore invalid (written to fez errolog).

 

We have ingested through the Fez batch utility 5000 images.  Needless to be
said, each record then must be edited at least once to add specific metadata
and to upload additional files, usually three or more files logically
related to each object originally created through the batch-ingest process.
This editing and reindexing is expected to be performed frequently, as the
repository gets populated. 

 

Is there a way to regulate or configure settings to avoid that problem of
datastream IDs and filenames growing too large?  If this cannot be
circumvented, then Fez will become useless for our purposes.

Also, can versioning be turned off, and if so, then how?  While indeed we
would prefer to allow versioning for all the Fez Fedora datastreams, until
we populate our repository with "permanent", "stable" records (that is,
updated and "finalized" to an extent that numerous updates become minimal),
we need to avoid the serious loss in performance and severely increased
processing time to reindex even a handful of fez fedora objects, much, much
more for a sizable number or even a complete collection, because of all the
additional processing of auditing, purging internally stored datastreams,
and then recreating the content with growing name lengths and superceding
versioning for each serialized object.  That, as you know, becomes a major
chore just to make even a simple typo correction.

 

Another major issue that has surfaced is that, as we assign descriptions to
file uploads, the datastream labels keep reverting to the original file
names, after one or more form edits, even though I have ascertained that the
file 'class.fedora_api.php', is written to read as posted in:

 [Fez-users] saving wrong file description when creating record (2006-08-15
00:19)

 

I can set the labels in the datastreams manually (from the original
filenames to the preferred descriptive text), and they show up properly,
until another submit (publish) or reindex is performed.  There is no method
of editing the attached file descriptions programmatically (unless I have
grossly overlooked something), and purging attachments just to be able to
restore the preferred descriptions is highly impractical for thousands of
records with multiple attached files.  That only makes the serialized object
grow and grow, as stated above.   Have I missed anything from another
discussion that resolves this issue of the description labels not getting
saved?

 

I am running Fez 1.3 rc3, with Fedora 2.1.1 on Windows XP SP2

 

Any input on resolving these would be appreciated.
