# Dataset of Dataflow Diagrams
This repository contains of {len(dataset)} manually created dataflow diagrams (DFDs) of microservice applications found on GitHub. The dataset is published as an additional contribution to "Automatic Extraction of Security-Rich Dataflow Diagrams for Microservice Applications written in Java" [Simon Schneider, Riccardo Scandariato]. Each folder in the [`dataset`](dataset/) directory contains one DFD in a [CodeableModels](https://github.com/uzdun/CodeableModels)-format that can be executed to generate PNG, SVG and TXT files for the DFD. Each model refers to stereotypes and metaclasses from the [metamodel](microservice_dfds_metamodel.py) which needs to be imported. This repository already contains rendered versions for each model, thus setup and rendering is only necessary once changes to the models are made.
