Dc.title missing

[Massimiliano CILURZO]

Dear all,

  We have Dspace 6.4 on our server. Yesterday the system was blocked saying DC.title missig. Looking in the metadata registry we added the metadata DC.title but even if the system restarted we couldn't see the community, collection of files on the items. We had tonwrite again the name of the community and collection but for the files they are a lot how i I can ripristinate the system? In every item the DC.title Is missing and even if you add It the file It Is still without già name and It Is not visibile in the item list.

Could you help us?

Thanks

Best regards 

Massimiliano

Hi Massimiliano,

Can you restore the database from a backup? That'd be the easiest way to restore any lost dc.title data.

To restore from a database backup, you'd want to use PostgreSQL's backup & restore tools as documented here: https://wiki.lyrasis.org/display/DSDOC6x/Storage+Layer#StorageLayer-MaintenanceandBackup

Or, if you were backing up using AIPs, then there's a restoration process available there as well. See the AIP Backup & Restore docs: https://wiki.lyrasis.org/display/DSDOC6x/AIP+Backup+and+Restore

If you do not have a backup, then the only other option may be to use the Batch Metadata Editing tool to add "dc.title" fields to all Items *in bulk*.  This would require exporting Item metadata to a CSV, editing that CSV to add the "dc.title" field one-by-one for each Item, and reimporting the CSV.  See the documentation on batch metadata editing: https://wiki.lyrasis.org/display/DSDOC6x/Batch+Metadata+Editing

If none of those work for you, your only other option would be to unfortunately edit each Item one-by-one from the Admin User Interface, and add the "dc.title" values for each.  That would be tedious work though, so I think you'd want to try using the Batch Metadata Editing tool instead.

Dear Tim, 

   Thanks for answering the question, unfortunately we haven't a backup.

I'll try with the CSV files.

Now if I try to insert a new item give error and I can't do it.

If I add the dc.title field to all items according to you I could add new item again?

The error is this if I try to save or go next on the item submission.

Dear Tim,

   I tried to add dc.title for one single item withe the item editor.

But even if I add the dc.title the file of the item it is still invisible.

I can see it only with the item editor and for the license file I can't see the filename. I can see the link to the license file only  with the developer option of the browser.

I have to add again the file manually to see it on the item view. ( in the attachment you could see in the bitstream I can't see the name of the files.

Could I do something?

Thanks

Best regards

[DSpace Technical Support]

Hi Massimiliano,

These questions are very difficult for me to answer because DSpace 6 is no longer under support (as of July 1, 2023) and therefore I do not have a DSpace 6 installation running anywhere for me to reference.  I also don't have the time to install this old system from scratch to provide detailed support on it.

That said, I know that with DSpace 6 both Items and Files (Bitstreams) stored their name/title in the "dc.title" field.  Since it sounds like you've deleted all dc.title fields (or somehow cleared them out in your database), this has resulted in all Items & Files having no title/name.

In DSpace 6, I'm worried there may be no easy way to fix this scenario.  With Items, you can use the Batch Metadata Editing that I mentioned in my prior email. But that tool will not work for files (bitstreams).  From your screenshots, it looks like the DSpace 6 Admin User Interface is not letting you edit the files (bitstreams) because they have no name (no "dc.title").

The only options I can think of would be to do ONE of the following:

1.  Upgrade to DSpace 7 immediately, migrating your data in your database over using the Migration Process in our documentation.  This would be beneficial because you would be able to edit the names of "Untitled" files.  In DSpace 7, if a file has a missing "dc.title", it will appear in the User Interface as "Untitled".  You can then click on it and edit it to add the missing title.  However, I will warn this is not an easy upgrade.  Upgrading to DSpace 7 requires using the new User interface, see the "Significant Changes" section of the Upgrade guide.

2. If you are highly technical, you could look more closely at the code in the DSpace 6 user interface (either XMLUI or JSPUI) for that "Item Bitstreams" tab (in your screenshot) and try to modify the code to ensure that any files with no "dc.title" show up as "Untitled" instead of having no name.  This would make them clickable in DSpace 6, so that you could edit the name.  I don't have a guide for how to do that though, as this is a feature that was first added in DSpace 7.

3. If you are highly technical, you might be able to also do this at the database layer.  You'd have to create a new "metadata_value" entry (in that table) which references the "bitstream" table and the "dc.title" field (listed in "metadatafieldregistry" table).  I don't have a SQL query to do that change, but it would be possible.  I'm not sure if anyone else on this list has done this before or has SQL to share.

4. Finally, you could consider hiring a DSpace expert from our Registered Service Providers who can do one of those above three options on your behalf.  

Unfortunately, because you don't have a backup of your server, this is much more complex to try to fix.  This isn't something I'd be able to walk you through (I'm not able to provide this level of complex one-on-one support, that's not my role).  It'd really require expertise with DSpace to help you to restore/recreate your data since the backup is missing.

Again, I'd stress that DSpace 7 and DSpace 8 are much more stable systems when it comes to these sorts of problems.  If you had been using one of those versions, then any object in DSpace without a "dc.title" would simply appear as "Untitled" and you'd still be able to edit them from the Admin User Interface.  But, in DSpace 6, I don't believe this feature existed, so your options are much more limited.

I wish there was more advice I could offer, but that's all I can think of.   Hopefully, if someone else has encountered this issue before or has a different idea, they'll share it with you on this email thread.

Good luck,

Tim

Dear Tim,

    Thanks for your suggestions even if aren't Easy I'll try to fix this problem 
Just for clarification I haven't deleted anything I have found the system with this problem.

Thanks again

Dear all, 

   Even if I put the dc.title in every single item I can't see the file attached in the item view.

How I could make the files visible. In the admin panel of the item I can see the file in the bistream Window.

Thanks for your help

Best regards 

Massimiliano
