Backend conversion module for BattInfoConverter

BattINFO Converter

Overview

BattINFO Converter is a Python-based web application that simplifies the semantic annotation of battery metadata. It converts coin cell battery metadata from an Excel-based schema into a JSON-LD format using the BattINFO ontology, ensuring standardized and machine-readable metadata. This tool is designed for non-technical users, eliminating the need for manual JSON-LD creation. Researchers only need to fill in an Excel schema (visit BattINFO converter to learn more), and the converter automates the transformation process, enhancing data interoperability, reproducibility, and FAIRness. By adopting BattINFO Converter, research groups can ensure that their battery metadata is structured, shareable, and reusable, facilitating better collaboration and advancing battery research.

The BattINFO converter web application was developed by Dr. Nukorn Plainpan and Prof. Dr. Corsin Battaglia at Empa, the Swiss Federal Laboratories for Materials Science and Technology in the Laboratory Materials for Energy Conversion. We acknowledge stimulating discussions and support from Dr. Simon Clark, SINTEF as well as the help of Dr. Graham Kimbell, Empa in designing the BattINFO converter app logo and provding sanity check for the code quality, especially in the area of parameter type hinting. The development of BattINFO converter was supported by funding for the Battery2030+ initiative from the European Union’s research and innovation program under grant agreement No. 957213 and No. 101104022 and from the Swiss State Secretariat for Education, Research, and Innovation (SERI) under contract No. 2300313 as well as funding for the PREMISE project from the open research data program of the ETH Board
