### Profiles
- Different profiles define specific ways to handle credentials, revocation, and proof mechanisms to ensure interoperability.

## Characteristics per protocol

| Characteristics | DCP | OID4VC |
|------------------------------------------------|---------------------------------|---------------------------------|
| Governance Authority | Eclipse Foundation | OpenID Foundation |
| Scope | Verifiable Credential exchanges | Verifiable Credential exchanges |
| supported VC formats | [W3C VCDM v1.1](https://www.w3.org/TR/vc-data-model/) | format agnostic*: [W3C VCDM 1.1](https://www.w3.org/TR/vc-data-model/), [W3C VCDM 2](https://www.w3.org/TR/vc-data-model-2.0/), [IETF SD-JWT VC](https://datatracker.ietf.org/doc/html/draft-ietf-oauth-sd-jwt-vc-09), [ISO mDL](https://www.iso.org/standard/69084.html), [AnonCreds](https://hyperledger.github.io/anoncreds-spec/), ... |
| Support of decentralised identifiers (W3C DID) | Yes | Yes |
| Support of asynchronous VC issuance | Yes | Yes |
| Support of Human-in-the-loop VC issuance | No | Yes |
| Support of Machine-to-Machine VC issuance | Yes | Yes |
| Supported data exchange protocols** | Eclipse Dataspace protocol (DSP)| Eclipse Dataspace protocol (DSP), TM Forum API, ... |

*: interoperability is achieved via the specification of OID4VC profiles
**: to be noted that those data exchange protocols are credentials format agnostic and no normative binding between a data exchange protocol and a verifiable credential exchange protocol has been identified.

Last two rows where extensively discussed and statements are not yet proven (e.g. OID4VC support of DSP). What about to add the official statement on the relationship between DSP, OpenID4VC, DCP, and Trust Frameworks that was just approved by the EDWG and can be found here.

## Eclipse Decentralized Claims Protocol (DCP)
In the DCP specification the generic Issuer-Holder-Verifier Model is extended and mapped to the needs of dataspaces and the organizations participating.
