Industry Standards
Sector standards — healthcare, payments, trade, travel, education and the rest. 99 in the catalog.
Many of these also appear in the Data Models catalog, where they are read as data models rather than as standards applied in API operations — with a layer, a domain, a licence and a modernity score.
Browse the data models →What a ruleset could actually check
A ruleset lints a structured document. Most industry standards are not structured documents in that sense, so sorting them by what a linter could inspect gives four very different groups. Every entry's tier is computed from the schema forms its body publishes — 64 of 99 have an artifact that can be fetched at source.
| A | 31 | The standard is an API description. A ruleset can assert conformance. |
| B | 36 | A data model inside API descriptions. A ruleset can check a subset — passing it is not conformance. |
| C | 13 | The wire format is not a structured document. Only the API around it can be governed. |
| D | 12 | No wire format at all — a methodology, taxonomy or identifier scheme. Nothing to lint, ever. |
| — | 7 | Not established in the last verification pass. Stated rather than guessed at. |
