Eclipse Dataspace Decentralized Claims Protocol

The Eclipse Dataspace Decentralized Claims Protocol (DCP) defines an interoperable overlay to the Dataspace Protocol (DSP) Specifications for conveying organizational identities and establishing trust in a way that preserves privacy and limits the possibility of network disruption. 

The scope of Eclipse DCP specification includes:

- Specifying a format for self-issued identity tokens
- Defining a protocol for storing and presenting Verifiable Credentials and other identity-related resources
- Defining a protocol for parties to request credentials from a credential issuer

Eclipse DCP supports multiple trust anchors and allow participants to manage and verify presentations without needing third-party systems outside their control. Note that it is not a requirement for Eclipse DCP to specify a decentralized or "self-sovereign" identity protocol, but it may be based on it.  

The following are out-of-scope for Eclipse DCP:

- The definition of verifiable credentials types and schemas. This work should be done by other expert groups aligned with industry and use-case-specific requirements.   
- The definition of semantic models for trust. The creation of semantic trust models should be done by other expert groups and aligned with DCP through the *W3C Verifiable Credential Data Model*.
- The definition of specific ODRL policy vocabularies. This work should be done by other expert groups aligned with industry and use-case-specific requirements.
