These standard interfaces, all of which are implemented in HTTP, support session management, collection discovery and evaluation, metadata searching, metadata retrieval, and online holding retrieval. An XML-based metadata encoding scheme and a simple boolean query language have also been developed. The architecture described by these interfaces has been implemented at UCSB. 1 ADL Background The Alexandria Project [1] is a consortium of researchers, developers, and educators, spanning the academic, public, and private sectors, exploring a variety of problems related to distributed digital libraries for georeferenced information.
