An extensible digital library is comprised of a library server and an object server. The library server stores tables describing the digital library, wherein it uses a relational database server to manage the storage of the tables describing the digital library. The object server stores objects referenced by the tables describing the digital library. Two application programming interfaces (APIs) are provided. A first API is coupled to the library server and the object server and provides functions for accessing the stored tables and the stored objects via the library server and the object server. A second API is coupled to the first API and the relational database server and provides functions for accessing the stored tables via the relational database server.
