Metadata is detailed information, such as experimental methods and analysis conditions, associated with experimental data. Metabolomics is a research field that exhaustively studies metabolism compounds. Since each research phase of sample preparation, instrumental analysis, and data analysis is extremely complicated, metabolomics experimental data is usually accompanied with a vast amount of metadata.
Metabolonote is a specialized database system for metadata management. This system aims to promote the publication and utilization of metabolomics data by simplifying the metadata record process. Separation of the management of metadata from experimental data has the following two advantages: (1) Multiple databases can share the same metadata, and (2) Data can easily be publicized.
