To figure out some basic problems in current digital region construction, this paper puts forward the concept of digital region application infrastructure (DRAI), and analyzes the research background, reference model and application supporting platforms for information sharing. DRAI is on the top tier above network infrastructure and spatial data infrastructure. It is composed of a series of information service organizations, management regulations, standards and norms, key technologies and application supporting platforms, and provides fundamental supporting services for various regional information system projects, such as e-government, e-business, digital cities, digital communities, LBS, etc. Information service organization is the main body of DRAI, providing "bridge" for information consumer and information provider. The core parts of DRAI are application service platforms, which provide unified frameworks and solutions for regional information sharing and exchanging. Among the platforms, the metadata management and catalog services platform provides "one-stop" entrance for information registration and query; the information sharing and cooperation platform provides information sharing and exchanging services among distributed databases; the spatial information web services platform realizes the centralized sharing of geospatial information. Finally, the paper summarizes the achievements of Digital Fujian which based on DRAI, and images the requirements and development of Digital Fujian Project in 11th Five-Year Plan period.
