+ * Lineage tracking support for Apache Beam pipelines.
+ *
+ * <p>This package provides a plugin mechanism to support different lineage implementations through
+ * the {@link org.apache.beam.sdk.lineage.LineageRegistrar} interface. Lineage implementations can
+ * be registered and discovered at runtime to track data lineage information during pipeline
+ * execution.
+ *
+ * <p>For lineage capabilities, see {@link org.apache.beam.sdk.metrics.Lineage}.
