OpenLineage is an Open standard for metadata and lineage collection designed to instrument jobs as they are running. It defines a generic model of run, job, and dataset entities identified using consistent naming strategies. The core lineage model is extensible by defining specific facets to enrich those entities.
OpenLineage defines the metadata for running jobs and the corresponding events. A configurable backend allows to choose what protocol to send the events to.
A facet is an atomic piece of metadata attached to one of the core entities. See the spec for more details.
The specification is defined using OpenAPI and allows extension through custom facets.
