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<p>Scope\nThe group will focus on the technical specifications required to bind physical objects to the digital world using the W3C&#8217;s foundational standards for Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs).\n<\/p>\n\n<ul>\n<li>Universal Addressing: Develop protocols for assigning and resolving DID-native addresses to discrete physical units (at Batch, SKU, or Serial-level granularity).<\/li>\n<li>Attestation Schemas: Define data models and vocabularies for &#8220;Event-Based Attestations&#8221; that document a physical asset&#8217;s lifecycle. Core event types include, but are not limited to:<\/li>\n<li>Origin: Proof of creation, mining, or manufacture.<\/li>\n<li>Transfer: Change of custody or ownership.<\/li>\n<li>Transformation: Processing, assembly, or modification.<\/li>\n<li>Disposition: Recycling, decommissioning, or end-of-life.<\/li>\n<li>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.<\/li>\n<li>Implementation &amp; Interoperability: Create guidelines for integrating UORA with existing business systems (e.g., ERP, SCM) and networks to ensure practical adoption.<\/li>\n<\/ul>\n\n<p>Deliverables\n<\/p>\n\n<ul>\n\n<li>UORA Core Specification: A technical document defining the architecture for DID-native object addressing and resolution.<\/li>\n<li>Universal Resource Attestation Schemas: A library of  vocabularies and data models for cross-industry lifecycle attestations.<\/li>\n<li>Secure Physical Binding Protocol: A specification outlining methods and best practices for securely linking digital DIDs to physical objects.<\/li>\n<li>Implementation Guidelines and Use Cases: Documentation providing practical integration pathways, reference architectures, and business case examples to accelerate adoption.<\/li>\n<\/ul>\n\n<p>Success Criteria<\/p>\n\n<p>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<p>Out of Scope<\/p>\n\n<ul>\n<li>Development of new blockchain or distributed ledger protocols.<\/li>\n<li>Creation of new cryptographic primitives.<\/li>\n<li>Mandating specific commercial hardware, sensor, or IoT platforms.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-dots\"\/>\n\n\n\n<p>In order to <a href=\"\/community\/uora\/join\">join the group<\/a>, you will need\n    a <a\n            href=\"\/account\/request\/\">W3C account<\/a>.
