add local metadata to existing item

[Shawn Kiewel]

I’m looking to add local schema metadata to existing items. From my readings this doesn’t seem possible. First I looked at using ItemUpdate to update the metadata, but according to https://wiki.duraspace.org/display/DSDOC6x/Updating+Items+via+Simple+Archive+Format, it only does metadata fields defined in dublin_core.xml. Then I thought of using batch metadata editing, but https://wiki.duraspace.org/display/DSDOC6x/Batch+Metadata+Editing under file structure says that the fields need to be Dublin core. My searches for related posts came up empty. I do know that importing a new item with the local fields is working, but I’m not sure I can think of another way to import the local schema with just metadata. Think I have to resort to removing the items and importing them as “new” objects? Admittedly, this is my fallback position anyway, because I fear there is a chance that simply editing the metadata won’t trigger the embargo code, so I’d have to reimport the objects anyway, since that is proven working.

Hello Shawn,

the easiest way to update metadata is the batch metadata editing. It
should work with any metadata field which is registered in your
instances metadata registry regardless of the schema.

So first register your schema in your instance and add the field(s) to
this schema.
On the UI log in as administrator then Administer -> General Settings ->
Metadata Registry
At the bottom of the list is the point where you can create the schema
"Create a new schema by entering a namespace/name or edit an existing
one by clicking the update button. The schema name must be less than 32
characters and cannot include spaces, periods or underscores. "
Once created click on the schema in the list and add your fields.

Hope this helps

Thank you, Claudia. I was able to successfully update the metadata using the batch tool. Perhaps the docs should be updated to specify that other schemas can be used?

However, just as I feared, just updating the metadata did not trigger the embargo setting. Additional searching lead me to this post by Terry that confirms such (wish I'd found it earlier): http://dspace.2283337.n4.nabble.com/Batch-add-edit-embargo-dates-td4685346.html

Looks like the only solution is to use the ItemUpdate with the Simple Archive Format to replace the items. That should trigger the embargo process. My only unsure thing at the moment is how to format the mapfile, since these records were all imported via batch metadata import, so no mapfiles exist, but I'm about to do some experimentation that should give me that info.

Thanks,
Shawn

For anyone following along at home and future googlers, using ItemUpdate with the replace option will replace the existing item and retrigger the embargo setting. Also, the mapfile format for importing is a simple text file with:

directory_name item_handle
directory_name item_handle
