Guha, Shaun Smith); published as an open GitHub project (ards-project/ard-spec) with no formal standards body yet; contributions acknowledged from AWS, Cisco, Databricks, GitHub, GoDaddy, Nvidia, Salesforce and Snowflake |\n| Status (issuer's words) | Active, versioned schema framework | Proposal |\n| Version | v1.1.0 (2026-07-10) | v0.91 (2026-08-26) |\n| Form / transport | document format | well-known file |\n| Found at | none | /.well-known/ard.json |\n| Implementation | shipping | multi-implementation — agenticweb.wiki /check/ probe (13/268 origins on /.well-known/ard.json; 43/268 on predecessor /.well-known/ai-catalog.json) |\n| Evidence | 2 verified, 1 reported | 2 verified, 2 reported |\n| Primary use case | Describe an agent's capabilities | Let agents discover my API or service |\n| Last verified | 2026-10-23 (current) | 2026-10-23 (current) |\n| Specification | [https://schema.oasf.outshift.com/](https://schema.oasf.outshift.com/) | [https://raw.githubusercontent.com/ards-project/ard-spec/main/spec/ard.md](https://raw.githubusercontent.com/ards-project/ard-spec/main/spec/ard.md) |\n\n## When to use which\n\n- Choose Open Agentic Schema Framework when your question is “How can an agent's skills, domains, deployment modules and identity be described using a shared, versioned taxonomy so registries can classify and filter it consistently?” and you accept its maturity: status \"Active, versioned schema framework\", implementation shipping.\n- Choose Agentic Resource Discovery when your question is “Where are an organization's discoverable agentic resources (MCP servers, A2A agents, skills, registries), and how can they be found by search rather than pre-installed one at a time?” and you accept its maturity: status \"Proposal\", implementation multi-implementation (agenticweb.wiki /check/ probe (13/268 origins on /.well-known/ard.json; 43/268 on predecessor /.well-known/ai-catalog.json)).\n\nGuidance is derived from the two records (question, status, implementation, prerequisites, pairings), not from opinion. Each record's page carries its numbered references.\n\n## Read the full articles\n\n- [Open Agentic Schema Framework](/protocols/oasf/): How can an agent's skills, domains, deployment modules and identity be described using a shared, versioned taxonomy so registries can classify and filter it consistently?\n- [Agentic Resource Discovery](/protocols/ard/): Where are an organization's discoverable agentic resources (MCP servers, A2A agents, skills, registries), and how can they be found by search rather than pre-installed one at a time?\n\nAsk the MCP server to compare any two: the compare-protocols prompt, or get on both ids.
