Thanks, that additional bit of information helps.

I am also ok with the proposal.

This approach simplifies the related topics:

 * Equivalence testing (use [1]).
 * Minting policy: Anybody can mint their own absolute URLs.
 * Identified resources: We can decide later, have flexibility, etc.

If we use the relative URL approach that I proposed in Option 1a then this potentially puts a lot of network load on whoever hosts the base URL.
