How to obtain thumbnail in OAI with OMP?

I need to show thumbnail in OIA metadata with OMP 3.1, How I can modify metadata to add this field?
Thanks.

Can you tell me how to index our papers in [Open Archives Initiative]OAI)?

Hi @IJELLH,

That’s not relevant to this topic; could you post it as a new question, including details about what you’re trying to do, and what version of our software (and which application) you’re using?
