  Meta-index of the specification languages used to describe APIs, events,
  schemas, and service interfaces across the modern API landscape. This repo
  is the META layer above the topical repos that profile each individual
  specification — it catalogs every major HTTP, event-driven, schema, and
  service interface specification along with its current version, governing
  body, license, and tooling ecosystem.

  description: >-
    The OpenAPI Specification (formerly Swagger) is the dominant industry
    standard for describing HTTP-based RESTful APIs. OAS describes endpoints,
    operations, parameters, request/response schemas, authentication, and
    examples in a machine- and human-readable format. The active versions
    are 3.0.x and 3.1.0 (which is fully aligned with JSON Schema 2020-12).
    OpenAPI is governed by the OpenAPI Initiative, a Linux Foundation
    project, under the Apache 2.0 license.

    AsyncAPI is the open standard for describing event-driven and
    message-driven APIs across protocols such as Kafka, AMQP, MQTT, WebSocket,
    NATS, and SNS/SQS. AsyncAPI 3.0 (December 2023) decoupled operations from
    channels, enabling clearer modelling of pub/sub, request/reply, and
    streaming patterns. AsyncAPI is governed by the AsyncAPI Initiative

    The current stable dialect is Draft 2020-12. Governance is moving toward
    a chartered standards body (JSON Schema Foundation), with the IETF as
    the historical sponsor; reference implementations and tooling are MIT
