Guideline for developing and displaying content on the Internet of Impact
The purpose of documents in the Internet of Impact is to record information in a stateful way. The ixo protocol standard is that a document must be:
- 3.Semantically interoperable
- 4.Universal addressable
- 9.Persistently available
- 10.Private by design
The ixo protocol defines a set of standard document types, which are used as building-blocks.
Each identifiable subject in the Internet of Impact has a Decentralised Identifier (DID). A specifically formatted document is associated with a DID, the DID Document (DDO), which is based on the W3C specification.
The following DDO document subjects are defined in the ixo context:
- Cell document
- Project document
- Oracle document
- Bond document
- Data Asset document
The generic structure of an ixo protocol DID Document is illustrated below.
Claims are high-definition data objects which encode information in a way that is portable, self-declarative and verifiable. Claims comply with the document standards by implementing the following features:
- Subjects are identified in a way that can be authenticated, using a DID.
- A schema context is declared, which resolves the claim data to a set of standard semantic definitions.
- An issuer is identified and authenticated, using a DID.
- The claim is cryptographically verifiable by its hash value and signatures.
- The claim object is content-addressable by its hash value (using the IPLD specification).
The following claims categories are defined in the ixo context:
- Identity claim (credential)
- Impact claim
- Evaluation claim
- Dispute claim
- Transaction claim
The basic structure of an ixo protocol Claim is illustrated below.
