Overview

The Battery Knowledge Base (BKB) collates metadata records of battery data sets to support FAIR data management and integration with the Semantic Web. To maintain some quality control, the BKB links with curated data sources. The preferred platform for BKB dataset submissions is the Battery Knowledge Base Community on Zenodo. This How-To guide outlines the recommended process for pre-processing data and submitting for inclusion in the BKB.

Serialize in an open file format

To maximize the accessibility and re-usability of datasets, submissions should contain only data in file formats that are open and accessible. Proprietary formats are not accepted. Accepted formats include:

*If CSV files are used, make sure that numbers use a decimal point (.) and not a comma (,) ! To avoid any potential issue, it is recommended to use a tab delimiter instead of a comma delimiter in CSV submissions.

Format	Description	MIME Type
PARQUET	Columnar binary format ideal for large-scale structured data	application/vnd.apache.parquet
TXT	Unstructured or line-based plain text, often used for configs	text/plain
JSON	Structured, hierarchical data format for metadata or results	application/json
CSV*	Plain-text tabular data with comma-separated values	text/csv

Adopt a standard table schema

The table schema for the dataset should adhere to an accepted standard or provide the necessary metadata to interpret the meaning of the column names. It is recommended to use the Battery Data Format table schema. For more information on how to serialize your data in the battery data format, please refer to this dedicated How-To guide.
