# Standards

> Which open protocols and formats cloud, data, AI and developer-tool vendors support (Model Context Protocol, Agent2Agent, OpenAI-compatible API, ONNX, OpenTelemetry, OpenLineage, Apache Iceberg, Delta Lake, Apache Arrow, Apache Hudi, Apache Parquet, SQL:2023, SPIFFE, OAuth 2.0 and OpenID Connect, FIDO2 and passkeys, C2PA Content Credentials, SPDX, CycloneDX), each backed by an evidence link and the date it was first seen. It grows: 259 vendors so far (+195 in 30 days), 18 standards so far.

So far Standards holds 733 pieces of evidence and 52 dated changes from 553 sources. List evidence comes from the specification projects' own pages (Apache Iceberg vendors, OpenTelemetry vendors, Delta Lake integrations, A2A partners, Hudi ecosystem, Powered by Arrow, ONNX tools, C2PA members, SPIRE adopters, SPDX tools, CycloneDX Tool Center, plus lists found by probing, which stay Unverified until checked). MCP servers come from the official MCP Registry, where a namespace can only be published by the vendor that owns the domain or GitHub org. Everything else comes from each vendor's own documentation, recorded with the sentence that names the standard. Depth target: every company in scope in the fru.dev registry (407 so far); docs researched for 320 of them. A run every Thursday at 11:30 UTC takes new registry companies, probes for new lists, re-reads every list and a rotating set of documentation pages. Last successful run: 2026-09-25 11:28:19 UTC.

## About this data

Evidence from the specification projects' own lists, the official MCP Registry and vendors' own documentation, found by a weekly run that also looks for new lists and new companies; entries from a list it has just found are marked unverified until checked by hand. The dataset grows as vendors adopt these standards, so confirm the version and scope with the vendor. Not legal advice. Logos via logo.dev; trademarks belong to their owners. Anonymous usage stats via Google Analytics. Readers can suggest corrections on any page.

Free to read. Cite "Standards (standards.fru.dev)" with a link. Responses are cached at the edge; keep to about 60 requests a minute. Entries marked unverified name the standard on a vendor page but nobody has confirmed it by hand. A listing says the vendor works with the standard; confirm the version and the products covered with the vendor.
