Abstract
In this paper, we present a new workflow representation model which is based on directory trees. We show the implementation of the model inside the EPISODES Platform — a portal for analyses related to anthropogenic hazards. Most workflow management systems use a DAG or custom programming language to encode a workflow. While this works well in many cases, we believe that there is a class of applications for which our approach is a better fit. This paper demonstrates how workflows can be efficiently represented in a file system tree. In our model, each workflow step is encoded as a directory. This enables natural encapsulation and modularity of the data alongside the workflow structure. We show how fundamental patterns such as sequence, merge, fork, and cycle are encoded. We believe that the presented directory tree-based representation is well suited for workflow systems that emphasize interactive composition processes. By implementing a rich GUI with built-in data visualization tools it may be particularly useful for exploratory programming where interactivity, dynamicity, and extensibility are crucial. The solution supports multi-level workflow nesting, reuse, sharing, and live collaboration in the workflow design process. The integrated workflow execution engine is scalable and supports automatic execution on high-performance distributed infrastructure. Our model was implemented and evaluated within the EPISODES Platform (Orlecka-Sikora et al., 2020), a workflow management system used by over 1400 users interested in research into anthropogenic hazards.
