Metanno v0

Metanno v0 is a JupyterLab extension for building custom annotation interfaces. It focuses on textual documents with structured entities and aims for modularity, customization, and interactivity. Core features include multi-line and nested span annotations, table-based relational annotations, multiple data types (hyperlinks, text, lists), and an immutable state that can be synchronized between the frontend and backend. The project compiles Python app classes to JavaScript using Transcrypt, enabling fast, browser-side execution while keeping Python code on the kernel side. To create an app, the user must modify one of the apps in recipes/*.py, and handle state management using a huge Redux-style reducer in select_state.

Last items in the v0 changelog:

  • Almost complete typescript conversion
  • Added column filters
  • Customizable undo/redo logic
  • Editable span annotations from a table view
  • Accessible return value of a Python call from front end (async calls)
