There are a lot of terms. For the sake of our readers, we need to use them consistently. And we should use as few unique ones as possible! I propose that we use these:
issuer - the entity that issues the credential.
holder - the entity that the credential is about, and who "holds" onto it.
consumer - the entity that needs to receive and analyze a credential.
Let's avoid terms like "recipient" - that has a flow feel to it and will change depending on how the data is flowing.
