Hello, long time no see friends. We have a question regarding custom metadata blocks. These can be enabled for datasets, can they also be enabled for collections (sub dataverse metadata)? Our use case is we want to mark which collections/sub dataverses can have their metadata exported and shown as collections in other online repositories. Thank you, Asbjørn

@Asbjørn Skødt hi! Yes, it's been a while.
I don't think we have an issue tracking this but before I ask you to create one, I'd like to tease apart at least two concepts.
Your use case reminds me of harvesting via OAI-PMH. Currently, datasets and files are supported but collections are not. Is that what you had in mind? Harvesting? Or did you have some other mechanism in mind exporting collections and making them discoverable in other systems?
Yes, nice to be in touch. I moved from operations to IT Architect here at University of Copenhagen and my tasks are somewhere else these days. However, we got a wish from the owner of the Danish Dataverse to harvest the metadata for dissemination in our national data catalogue based on the DCAT-AP-DK format specification.
It is very interesting what you inform us. Using the OAI-PMH endpoint would be ideal, what are your thoughts on accepting DCAT-AP and our nationalt variant DCAT-AP-DK as formats?
The use case is also to allow collections to be harvested. What are your thoughts on enabling these through the OAI-PMH endpoint?
There has been some recent chatter about DCAT here:
Support for Importing and Exporting DCAT Metadata #1592
I think it would take a fair amount of work to make collections harvestable. You're welcome to create an issue about this, though!
Also, congrats on the new job!
Thanks for the guidance. We look into it.
Sure, and please keep the questions coming!
@Asbjørn Skødt check out https://github.com/Dans-labs/dataverse-exporter-dcatap by @Paul Boon via https://github.com/IQSS/dataverse/issues/1592#issuecomment-3548051224
That's great!
Our OAI endpoint is not available. See: https://dataverse.deic.dk/oai
I can't find documentation on how to enable it here: https://guides.dataverse.org/en/latest/admin/harvestserver.html
How do we enable it? :)
Harvesting DCAT-AP and specific extensions into custom metadatablocks is also on our list of needed features.
@Asbjørn Skødt you can enable it in the superuser dashboard: https://guides.dataverse.org/en/6.6/admin/harvestserver.html#how-does-it-work
