JSON Structure is a data structure definition language that enforces strict typing, modularity, and determinism.
JSON Structure is a schema language that can describe data types and structures whose definitions map cleanly to programming language types and database constructs as well as to the popular JSON data encoding. The type model reflects the needs of modern applications and allows for rich annotations with semantic information that can be evaluated and understood by developers and by large language models (LLMs).

With JupyterHub you can create a multi-user Hub that spawns, manages, and proxies multiple instances of the single-user Jupyter notebook server. Project Jupyter created JupyterHub to support many users. The Hub can offer notebook servers to a class of students, a corporate data science workgroup, a scientific research project, or a high-performance computing group. JupyterHub brings the power of notebooks to groups of users. It gives users access to computational environments and resources without burdening the users with installation and maintenance tasks. Users - including students, researchers, and data scientists - can get their work done in their own workspaces on shared resources which can be managed efficiently by system administrators.
