W3C Invites Implementations of VC Data Integrity, Data Integrity EdDSA and ECDSA Cryptosuites, and VC JSON Schema

 The Verifiable Credentials Working Group invites implementations of the following Candidate Recommendation Snapshots:

• Verifiable Credential Data Integrity 1.0 describes mechanisms for ensuring the authenticity and integrity of Verifiable Credentials and similar types of constrained digital documents using cryptography, especially through the use of digital signatures and related mathematical proofs.
• Data Integrity EdDSA Cryptosuites v1.0 describes a Data Integrity cryptographic suite for use when creating or verifying a digital signature using the twisted Edwards Curve Digital Signature Algorithm (EdDSA) and Curve25519 (ed25519).
• Data Integrity ECDSA Cryptosuites v1.0 describes a Data Integrity Cryptosuite for use when generating a digital signature using the Elliptic Curve Digital Signature Algorithm (ECDSA).
• Verifiable Credentials JSON Schema Specification: Among other things, the [VC-DATA-MODEL-2.0] specifies the models used for Verifiable Credentials, Verifiable Presentations, and explains the relationships between three parties: issuers, holders, and verifiers. Verifiability, extensibility, and semantic interoperability are critical pieces of functionality referenced throughout the [VC-DATA-MODEL-2.0]. This specification provides a mechanism to make use of a Credential Schema in Verifiable Credential, leveraging the existing Data Schemas concept.

W3C updates its 2023 Process Document

 W3C has approved the updated 2023 Process Document, which takes effect today. The only change is expanding the W3C Technical Architecture Group (TAG) from 6 elected and 3 appointed participants to 8 elected and 3 appointed participants. 

The TAG consists of: Tim Berners-Lee who is a life member; 3 participants appointed by the W3C Team; 8 participants elected by the W3C Advisory Committee following the AB/TAG nomination and election process. 

You can read the Disposition of Comments for rationale or peruse the diff from the previous version. 

W3C Process Document is developed by the Advisory Board’s Process Task Force working within the W3C Process Community Group. Comments and feedback on the Process Document may be sent as issues in the public GitHub Repository.

W3C Invites Implementations of RDF Dataset Canonicalization

 The RDF Dataset Canonicalization and Hash Working Group invites implementations of the RDF Dataset Canonicalization Candidate Recommendation Snapshot. RDF [RDF11-CONCEPTS] describes a graph-based data model for making claims about the world and provides the foundation for reasoning upon that graph of information. At times, it becomes necessary to compare the differences between sets of graphs, digitally sign them, or generate short identifiers for graphs via hashing algorithms. This document outlines an algorithm for normalizing RDF datasetssuch that these operations can be performed.
