An Open Standard for lineage metadata collection
APACHE-2.0 License
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 is an LF AI & Data Foundation incubation project under active development, and we'd love your help!
OpenLineage defines the metadata for running jobs and the corresponding events. A configurable backend allows the user 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.
The OpenLineage repository contains integrations with several systems.
