Request: Enable the possibility of adding unique identifiers for mappings

[alko-k]

In the NERC vocabulary server (NVS) we assign unique identifiers to each mapping and attach additional information to it e.g. provenance to strengthen trust. For mappings to be FAIR they themselves need to be discoverable accessible interoperable and reusable. The Unique identifier will make them discoverable, accessible and reusable but also allow assertions about combinations of mappings e.g. combined mapping A and mapping B to form mapping C. Doing this though goes hand in hand with the governance of mappings since mappings should not longer be deleted but deprecated. This is a discussion I would like to trigger in the semantic community.
