• Tracks user-defined items within user-defined hierarchical storage locations.
• Strongly-typed metadata with user-defined types.
• Rich search functionality; perform complex searches over item metadata with automatic pagination and sorting.
• Full API access for all operations.
• Full Java API for performing operations.
• Fine-grained capability based security model for operations; Safely write external services that can perform operations while maintaining the principle of least privilege.
• Command-line shell.
• Complete audit log; every operation that changes the state of the system is logged in an append-only log.
• Fully instrumented with OpenTelemetry.
• A small, easily auditable codebase with a heavy use of modularity for correctness.
• An extensive automated test suite with high coverage.
• Platform independence. No platform-dependent code is included in any form, and installations can largely be carried between platforms without changes.
• OSGi-ready
• JPMS-ready
• Support for Canonmill keystores.
• ISC license.

• Maven Central
• Quay.io

cardant: usage: cardant [command] [arguments ...]

  The cardant server command-line application.

  Use the "help" command to examine specific commands:

    $ cardant help help.

  Command-line arguments can be placed one per line into a file, and
  the file can be referenced using the @ symbol:

    $ echo help > file.txt
    $ echo help >> file.txt
    $ cardant @file.txt

  Commands:
    help          Show usage information for a command.
    initialize    Initialize the server and database.
    server        Start the server.
