Stencila is a platform for collaborating on, and publishing, dynamic, data-driven content. Our aim is to lower the barriers for creating data-driven documents and make it easier to create beautiful, interactive, and semantically rich, articles, web pages and applications from them.

This is v2 of Stencila, a rewrite in Rust aimed at leveraging two relatively recent and impactful innovations:

• Conflict-free replicated data types (CRDTs), and specifically the production ready, Rust-based Automerge v2, for de-centralized collaboration and version control.

• Large language models (LLMs)for assisting in writing and editing, prose and code.

We are embarking on a rewrite because CRDTs will now be the foundational synchronization and storage layer for Stencila documents. This requires fundamental changes to most other parts of the platform (e.g. how changes are applied to dynamic documents). Furthermore, a rewrite allow us to bake in, rather than bolt on, mechanisms to mitigate the risks associated with using LLM assistants for authoring documents (e.g. recording the actor, human or LLM, that made the change to a document).

We're in the early stages of this rewrite, and this document will be updated with a roadmap and other details soon.

We are currently tagging releases using a 2.0.0-alpha.X pattern (where we increment X on each release). The v1 branch can be browsed here.

Although v2 is in early stages of development, and functionality may be limited or buggy, we are taking a continuous delivery approach and releasing binary builds of alpha versions of the Stencila CLI tool and language packages. Doing so allows us to get early feedback and monitor what impact the addition of features has on build times and distribution sizes.

To install the latest release download stencila-<version>-x86_64-pc-windows-msvc.zip from the latest release and place it somewhere on your PATH.

To install the latest release in /usr/local/bin,

curl -L https://raw.githubusercontent.com/stencila/stencila/main/install.sh | bash

To install a specific version, append -s vX.X.X. Or, if you'd prefer to do it manually, download stencila-<version>-x86_64-apple-darwin.tar.xz from the one of the releases and then,

tar xvf stencila-*.tar.xz
sudo mv -f stencila /usr/local/bin # or wherever you prefer

To install the latest release in ~/.local/bin/,

curl -L https://raw.githubusercontent.com/stencila/stencila/main/install.sh | bash

To install a specific version, append -s vX.X.X. Or, if you'd prefer to do it manually, download stencila-<version>-x86_64-unknown-linux-gnu.tar.xz from the one of the releases and then,

tar xvf stencila-*.tar.xz
mv -f stencila ~/.local/bin/ # or wherever you prefer

The CLI is also available in a Docker image you can pull from the Github Container Registry,

docker pull ghcr.io/stencila/stencila

and use locally like this for example,

docker run -it --rm -v "$PWD":/work -w /work --network host ghcr.io/stencila/stencila --help

This repository is organized into the following modules. Please see their respective READMEs for guides to contributing.

• schema: YAML files which define the Stencila Schema, an implementation of, and extensions to, https://schema.org, for documents.

• json-ld 🏗️ In progress: A JSON LD @context for Stencila Schema generated from the files in schema.

• json-schema 🏗️ In progress: A JSON Schema for Stencila Schema generated from the files in schema.

• rust: Several Rust crates implementing core functionality and a CLI for working with documents that adhere to that Stencila Schema.

• docs 🏗️ In progress: Documentation, including reference documentation generated from schema and the rust CLI interface.

• examples 🏗️ In progress: Example of documents conforming to Stencila Schema.

• node 🧭 Planned: A Node.js package built on top of the Rust crates which provides interfaces to use Stencila from within Node.js.

• python 🧭 Planned: A Python package built on top of the Rust crates which provides interfaces to use Stencila from within Python.

• r 🧭 Planned: An R package built on top of the Rust crates which provides interfaces to use Stencila from within R.

We wouldn’t be doing this without the support of these generous, forward looking organizations.

Stencila is built on the shoulders of many open source projects. Our sincere thanks to all the maintainers and contributors of those projects for their vision, enthusiasm and dedication, but most of all for all their hard work! The following open source projects in particular have an important role in the current version of Stencila.

	Automerge	A Rust library of data structures for building collaborative applications.
	Clap	A Command Line Argument Parser for Rust.
	Rust	A multi-paradigm, high-level, general-purpose programming language which emphasizes performance, type safety, and concurrency.
	Serde	A framework for serializing and deserializing Rust data structures efficiently and generically.
	Similar	A Rust library of diffing algorithms including Patience and Hunt–McIlroy / Hunt–Szymanski LCS.
	Tokio	An asynchronous runtime for Rust which provides the building blocks needed for writing network applications without compromising speed.
