[Haskell-cafe] [ANN] NASA's Ogma 1.6.0

[Ivan Perez]

Hi everyone!

I'm thrilled to announce the release of Ogma 1.6.0!

NASA's Ogma is a mission assurance tool that facilitates integrating
runtime monitors or runtime verification applications into other
systems.

Use cases supported by Ogma include producing Robot Operating System
(ROS 2) packages [3], NASA Core Flight System (cFS) applications [4],
and components for FPrime [1] (the software framework used for the Mars
Helicopter). Ogma is also one of the solutions recommended for
monitoring in Space ROS applications [2].

Ogma is fully written in Haskell, and leverages existing Haskell work,
like the Copilot language [5] (also funded by NASA) and BNFC [6].

For more details, including videos of monitors being generated and
flown in simulators, see:

* What's changed

This major release includes the following improments:

- Update Ogma to be able to extract data from XML files, including
  standard formats used in MBSE tools.

- Provide a new diagram command capable of generating state machine
  implementations from diagrams.

- Make the ROS and F' backend able to use any JSON- or XML files as
  input, makes the ROS, F', standalone backends capable of using
literal Copilot expressions in requirements and state transitions.

- Extend Ogma to be able to use external tools to translate
  requirements, including LLMs.

- Make the F' backend able to use templates.

- Allow users to provide custom definitions for XML and JSON formats
  unknown to the tool.

- Fixes several other smaller maintenance issues.

- Upgrades the README to include instructions for external
  contributors.

This constitutes the single largest release of Ogma in number of new
features added, since its first release.

For details about the release, see:

* Releases

Ogma is released as a collection of packages in Hackage. The entry
point is https://hackage.haskell.org/package/ogma-cli.

* Code

The github repo is located at: https://github.com/nasa/ogma.

* What's coming

The next release is planned for Mar 21st, 2025.

We are currently working on a GUI for Ogma that facilitates collecting
all mission data relative to the design, diagrams, requirements and
deployments, and help users refine designs and requirements, verify
them for correctness, generate monitors and full applications, follow
live missions, and produce reports.

We also want to announce that both Ogma and Copilot can now accept
contributions from external users, and we are also keen to see students
use them for their school projects, their final projects and theses, and
other research. If you are interested in collaborating, please reach out to
ivan.perezdominguez at nasa.gov.

We hope that you are as excited as we are and that our work
demonstrates that, with the right support, Haskell can reach farther
than we ever thought possible.

Happy Haskelling!

Ivan
