Abstract: The metadata is a key issue of neuroimaging databaseresearches.However,the existing metadata organizational forms of neuroimaging data are too simplex to effectively support the systematic BI research oriented analytical queries for data information.The construction of metadata cubes can solve this problem.In this paper,a Data-Brain based approach is proposed to construct the metadata cubes of neuroimaging data.Based on the existing technologies related to data cube constructions,a type of novel metadata cube of neuroimaging data,i.e.,Provenance Cube,is defined.A Data-Brain based semi-automatic approach is also designed for Provenance Cube constructions.The construction instancestated in this paper shows that different topics oriented metadata cubes of neuroimaging data can be constructed quickly to support various analytical queries of data information coming from different aspects of systematic BI research.

Key words: Data-Brain, metadata cube, neuroimaging data, ontology, data warehouse
