a) is particularly interesting to me. I thought about giving people ability to create their own namespaces and used https://user.example.com https://user.example.com or https://example.com/user https://example.com/user as a namespace but tag URI looks cleaner. By the way why did you need human readable IDs? I'm asking out of curiosity because there is certain charm to just using UUIDs everywhere (and urn:uuid).
