The Physical Asset Attestation (UORA) Community Group has been proposed by Amir Hameed Mir:<\/p>\n\n\n\n
The mission of the Universal Object & Resource Attestation (UORA) Community Group is to develop a vendor-neutral, decentralized protocol for the identity, state verification, and lifecycle tracking of physical assets. By bridging the gap between physical objects and digital identifiers, UORA enables every resource to function as a first-class citizen of the internet, fostering global trust, transparency, and interoperability across supply chains and industries.<\/p>\n\n
Scope\nThe group will focus on the technical specifications required to bind physical objects to the digital world using the W3C’s foundational standards for Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs).<\/p>\n\n
Universal Addressing: Develop protocols for assigning and resolving DID-native addresses to discrete physical units (at Batch, SKU, or Serial-level granularity).<\/p>\n\n
Attestation Schemas: Define data models and vocabularies for “Event-Based Attestations” that document a physical asset’s lifecycle. Core event types include, but are not limited to:<\/p>\n\n
Origin: Proof of creation, mining, or manufacture.<\/p>\n\n
Transfer: Change of custody or ownership.<\/p>\n\n
Transformation: Processing, assembly, or modification.<\/p>\n\n
Disposition: Recycling, decommissioning, or end-of-life.<\/p>\n\n
Secure Physical Binding: Establish best practices and specifications for the tamper-evident linking of a digital DID to a physical anchor (e.g., via NFC, QR, cryptographic hardware, or IoT sensors) to verify possession and state.<\/p>\n\n
Implementation & Interoperability: Create guidelines for integrating UORA with existing business systems (e.g., ERP, SCM) and networks to ensure practical adoption.<\/p>\n\n
Deliverables<\/p>\n\n
UORA Core Specification: A technical document defining the architecture for DID-native object addressing and resolution.<\/p>\n\n
Universal Resource Attestation Schemas: A library of vocabularies and data models for cross-industry lifecycle attestations.<\/p>\n\n
Secure Physical Binding Protocol: A specification outlining methods and best practices for securely linking digital DIDs to physical objects.<\/p>\n\n
Implementation Guidelines and Use Cases: Documentation providing practical integration pathways, reference architectures, and business case examples to accelerate adoption.<\/p>\n\n
Success Criteria<\/p>\n\n
The Community Group will be considered successful when its core specifications are used by at least two independent, interoperable implementations to track physical assets across a multi-party supply chain.<\/p>\n\n
Out of Scope<\/p>\n\n
Development of new blockchain or distributed ledger protocols.<\/p>\n\n
Creation of new cryptographic primitives.<\/p>\n\n
Mandating specific commercial hardware, sensor, or IoT platforms.<\/p>\n\n\n
\n You are invited to support the creation of this group<\/a>.\n Once the group has a total of 5 supporters, it will be launched and people can join to begin work. In order to support the group, you will need a W3C account<\/a>.\n<\/p>\n\n\n\n Once launched, the group will no longer be listed as “proposed”; it will be in the list of current groups<\/a>.<\/p>\n\n\n\n \n If you believe that there is an issue with this group that requires the attention of the W3C staff, please send us email on site-comments@w3.org<\/a>\n<\/p>\n\n\n\n Thank you, The Physical Asset Attestation (UORA) Community Group has been proposed by Amir Hameed Mir: The mission of the Universal Object & Resource Attestation (UORA) Community Group is to develop a vendor-neutral, decentralized protocol for the identity, state verification, and lifecycle … Continue reading
