  Delta Lake is a graduated project of the Linux Foundation AI & Data
  Foundation providing an open source storage framework for building
  Lakehouse architectures. Originally contributed by Databricks, it adds
  reliability, quality, and performance to data lakes with ACID
  transactions, schema enforcement, time travel, and Iceberg/Hudi
  interoperability via UniForm. Delta Lake projects also include
  Delta Sharing (an open protocol for secure data sharing) and
  catalog-managed tables built on the Iceberg REST Catalog protocol.

    name: Delta Lake Storage Framework
    description: >-
      The Delta Lake storage framework defines the on-disk transaction log
      and protocol that adds ACID transactions, schema enforcement, and
      time travel to Parquet-based data lakes. Delta Lake exposes Spark,
      Rust, and Python APIs (delta-spark, delta-rs, deltalake) rather
      than a network API.

    name: Delta Sharing Protocol
    description: >-
      Delta Sharing is an open protocol for secure data sharing across
      organizations, defined as a REST API specification. Sharing servers
      expose endpoints for listing shares, schemas, and tables, and for
      retrieving signed URLs to underlying data files.

      Catalog-managed Delta tables delegate table scan planning to an
      external catalog using the Iceberg REST Catalog protocol, enabling
      interoperability with Unity Catalog and other catalog services.
