package kcidb

// Kernel CI report data. To be submitted to/queried from the common report database.
//
// Objects in the data are identified and linked together using "id" and "*_id" string properties.
// Each value of these properties must start with a non-empty string identifying the CI system which
// submitted the object, followed by a colon ':' character. The rest of the string is generated by
// the origin CI system, and must identify that object uniquely among all objects of the same type,
// coming from that CI system.
//
// Any of the immediate properties (except "version") can be missing or be an empty list with each
// submission/query, but only complete data stored in the database should be considered valid.
//
// E.g. a test run referring to a non-existent build is allowed into/from the database,
// but would only appear in reports once both the build and its revision are present.
//
// No special meaning apart from "data is missing" is attached to any immediate or deeper properties being omitted,
// when they're not required, and no default values should be assumed for them.
// At the same time, no properties can be null.
//
// Extra free-form data can be stored under "misc" fields associated with various objects throughout the schema,
// if necessary. That data could later be used as the basis for defining new properties to house it.
