API Commons Service Level Agreement

An API Commons schema for publishing a provider’s service level agreement layer as machine-readable data. Service levels: a profile of SLA4OAI documenting the x-apis-io extensions for promised and reported uptime.

The API Commons Service Level Agreement schema is one of eight business layers that make the political side of an API machine-readable, beside the technical contract. Service levels: a profile of SLA4OAI documenting the x-apis-io extensions for promised and reported uptime.

It profiles existing work rather than inventing: see SLA4OAI. Generated documents for catalog providers are stamped with x-apis-io-derivation and live in each provider’s repository; the schema, under Apache 2.0, is at github.com/api-commons/service-level-agreement.

Background: The Technical Side Translated. The Business Side Did Not.

Industry: api-specification
