The updated ASP OAI 2.0 Data Providers are available. The data providers are designed for three different architectures: database, file system, and mix of database and file system.
For the database architecture, the data provider uses a database for both the metadata and the administrative information. We use Microsoft Access as an example in this package. For the file system architecture, XML files provide all metadata and administrative information. For the mixed architecture, the metadata are stored as XML files while the administrative information is in a database.
