Using experience from Bloomberg, the post explains why Spectral rules cannot be one-size-fits-all: each rule is a negotiated agreement that needs its own versioning, communication, and named stewards. The German model's key insight is federating decisions openly via ADRs, public consultations, and a formal governance body — not just runtime enforcement. The author introduces a free browser-based tool at API Commons (Rule Federation) that visualizes which domains inherit, override, waive, or extend central rules, helping teams identify contested rules, missing stewards, and promotion candidates. ## Full article daily.dev links to this article rather than hosting it.

FAAI is Germany's federal API authorization infrastructure standardizing OAuth scopes across government APIs. It keeps coarse-grained permissions centralized at the platform level while decentralizing fine-grained permissions into domain federations called Fachverbünde, following a 'profile, don't invent' principle that favors adopting open standards over homegrown extensions. _Architects designing scope hierarchies can compare federated governance models like FAAI on daily.dev._ ### How can I structure Spectral rules for API governance across multiple teams with different needs? Combine a central rules registry in Git and NPM with a federated layer that lets domains override severity, waive rules, or maintain local rule catalogs, since a rule is effectively a negotiated agreement between the center and each domain rather than a fixed config line. Pull requests, commits, and ongoing communication about why each rule matters are what make adoption stick across teams. _Teams rolling out Spectral rulesets across domains can find governance patterns like this on daily.dev._ ### What does the Rule Federation tool from API Commons do? Rule Federation is a free browser-based tool that takes a machine-readable model of a central baseline ruleset plus the domains adopting it, then displays the results as a matrix showing which domains inherit rules as-is, which override severity and why, which have waived or deferred rules, and which have grown local rules worth promoting centrally. It also flags contested rules, unstewarded rules, and rules with no linked rationale, all stored as a single forkable JSON file. _Anyone evaluating tools for tracking API rule adoption across teams can follow developments like this on daily.dev._ ## Similar posts on daily.dev - [A Registry of Adoptable, Provenanced Governance Rulesets](https://daily.dev/posts/a-registry-of-adoptable-provenanced-governance-rulesets-urhaar8rf) · API Evangelist · 0 upvotes · 0 comments - [Federated Governance for AI Identities: Closing the 92% Visibility Gap](https://daily.dev/posts/federated-governance-for-ai-identities-closing-the-92-visibility-gap-i75sswt6l) · Security Boulevard · 0 upvotes · 0 comments - [Snowflake Builders Blog: Data Engineers, App Developers, AI, & Data Science](https://daily.dev/posts/snowflake-builders-blog-data-engineers-app-developers-ai-data-science-tloqtah2s) · Snowflake Community · 0 upvotes · 0 comments - [The Open API Governance Toolchain](https://daily.dev/posts/the-open-api-governance-toolchain-sk3zf1qjy) · API Evangelist · 0 upvotes · 0 comments - [6 Tips For Managing Multiple APIs](https://daily.dev/posts/6-tips-for-managing-multiple-apis-y5yhpobd9) · Nordic APIs · 0 upvotes · 0 comments --- Tags: [#oauth](https://daily.dev/tags/oauth) [View this post on daily.dev](https://daily.dev/posts/a-federated-api-governance-rule-registry-xwxlhepux) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"A Federated API Governance Rule Registry","url":"https://daily.dev/posts/a-federated-api-governance-rule-registry-xwxlhepux","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/a-federated-api-governance-rule-registry-xwxlhepux"},"datePublished":"2026-07-20T12:59:34.157Z","dateModified":"2026-09-13T21:18:50.742Z","description":"Drawing on a German government initiative (FAAI) that federates OAuth scopes across public-sector APIs, the author argues that enterprise API governance...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/186fe5178dfd3ba58e789bee35223eeb?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/186fe5178dfd3ba58e789bee35223eeb?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"API Evangelist","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"API Evangelist","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/a36244ae67bc4f41a605f780267ecb5f","url":"https://daily.dev/sources/apievangelist"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/a-federated-api-governance-rule-registry-xwxlhepux","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"oauth","timeRequired":"PT7M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"API Evangelist","item":"https://daily.dev/sources/apievangelist"},{"@type":"ListItem","position":3,"name":"A Federated API Governance Rule Registry"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/a-federated-api-governance-rule-registry-xwxlhepux#faq","mainEntity":[{"@type":"Question","name":"What is Germany's Föderale API-Autorisierungsinfrastruktur (FAAI) and how does it split OAuth scope decisions?","acceptedAnswer":{"@type":"Answer","text":"FAAI is Germany's federal API authorization infrastructure standardizing OAuth scopes across government APIs.
