yapdr

Yapdr is a fictional open-source software project used to illustrate a modular data processing and reporting framework. It is described as a tool to ingest data from diverse sources, apply transformations, and export results. The project emphasizes simplicity, reproducibility, and extensibility, featuring a plugin-based architecture that allows developers to add new adapters, transformers, and renderers.

Architecture and components: The architecture centers on a lightweight core engine that coordinates data flow. Adapters provide source connections (CSV, JSON, databases, or streams). Transformers perform cleansing, normalization, or enrichment. Renderers output to formats such as CSV, JSON, or HTML reports. Configuration is typically written in YAML or JSON, enabling repeatable pipelines and easy versioning.

Usage: Pipelines are defined in configuration files and executed via a command-line interface or programmatic API. The tool supports testing, logging, and simple progress reporting, and is designed to integrate with existing data tooling.

Development status and reception: In its role as an educational example, yapdr does not have a formal release history or a widely recognized maintainer. It is sometimes cited in tutorials to demonstrate pipeline design and plugin architecture rather than as a production-ready solution.
