Abstract
Many databases and platforms for human brain data have been established in China over the years, and metadata plays an important role in understanding and using them. The BrainBank Metadata Specification for the Human Brain Project and Neuroinformatics provides a structure for describing the context and content information of BrainBank databases and services. It includes six parts: identification, method, data schema, distribution of the database, metadata extension, and metadata reference The application of the BrainBank Metadata Specification will promote conservation and management of BrainBank databases and platforms. it will also greatly facilitate the retrieval, evaluation, acquisition, and application of the data.
