What is SWAN?

SWAN could refer to several different technologies or concepts, making a precise definition challenging without more context. Here are a few possibilities: 1. **SWAN (Simple Workflow Annotation Notation):** A lightweight ontology and associated tools for describing and executing scientific workflows. It focuses on interoperability and allows scientists to easily share and reuse workflows. 2. **SWAN (Server Written Application Notation):** This is a less common term, and information is limited. It may refer to a system or framework that utilizes server-side scripting or application development. 3. **SWAN (Service Workers Assistant Node):** This describes service worker orchestration and management tools. 4. **ROOT/SWAN:** An analysis environment based on CERN's ROOT data analysis framework, often used in high-energy physics. It allows interactive data analysis using Python or R within a web browser. 5. **A general acronym:** SWAN could also be an acronym specific to a company or project. Without more context, it is impossible to provide a precise definition.
