Hi David, Thanks for the heads-up. I believe you're right, and I've added a comment in the bug. Additionally, it should be possible to configure this per OAI-PMH set so that the provider can provide suppressed records to harvesters that actually need them while keeping them away from harvesters in "OPAC" context.

Hi Ere,

There’s been some discussion on Bug 31161 https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=31161 <https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=31161> about hiding records/items in OAI-PMH output, and I was keen to get your thoughts.

I’ve had a few different ideas over time, but right now I’m thinking that the best way to deal with hiding bib records is to mark them as “deleted” in the OAI-PMH feed.

Firstly, it would be a very easy change to make, which would probably not affect performance much at all.

Secondly, it would allow records that have been hidden to be removed from downstream systems automatically via OAI-PMH harvesters that support deletions.

Since it’s a small code change, I’m tempted to trial it locally using the OAI Config file to turn on this hiding mechanism.

Since you’re the person who has done the most work on the OAI-PMH server recently, I figured you’d be a good person to ask for feedback!
