Open Source Software Analysis

This section contains structural analysis and GUI/contribution planning documents for open-source projects. The goal is to incrementally understand how these software packages work so that contributors can build web-based GUIs and make meaningful contributions.

Projects

Project	Description	Pages
Pandapower	Python library for power system modeling and analysis (power flow, OPF, short-circuit, state estimation, time series)	Architecture & Structure • Web GUI PRD
ONLYOFFICE Nextcloud	Nextcloud app integrating ONLYOFFICE Docs for collaborative document editing (DOCX, XLSX, PPTX, PDF)	Repository Analysis

How To Use These Documents

Architecture / Structure — Read first. Explains the codebase layout, what each folder and file does, and the computation flow. Aimed at newcomers.
GUI PRD — Functional requirements for incrementally building a web GUI. Milestones ordered from most-used features to specialized ones.
Repository Analysis — For contribution-focused projects: what the code does, how it's structured, and where common contributions fit.
