Dear Dr Khan,
I checked your Dspace. I see that you do not use Handle Server for persistant identifier in your content. The "123456789" prefix in below uri from your Dspace is just for testing purposes.
On the other hand, you can add DOI number of your content as a metadata. We generally use dc.identifier.doi metadata for storing DOI.
Because all content in Dspace may not have a DOI, a handle number generated by the handle-server better fits in this requirement. Handle prefix is purchased from
handle.net
I hope this clarifies.
