Alexandria Digital Library Services ADL middleware server

The ADL middleware server is a distributed, peer-to-peer software component that provides mediated programmatic access to digital library collections. To clients it presents standard library services in the areas of metadata search, retrieval, and ranking; access control; and collection management and organization. To collections it presents a standard framework in which heterogeneous, collection- and/or item-specific metadata can be mapped and returned. The middleware server works cooperatively with a centralized collection discovery server and, in peer-to-peer fashion, with other middleware servers.

The ADL middleware is intended to be used as a services layer. It does not have an end-user interface. An end-user interface for the previous version of the ADL library software is hosted at: http://webclient.alexandria.ucsb.edu/

The software provides java, web, and java RMI interfaces for the development of digital libraries and end user interfaces. The most developed backend is for accessing information in the SQL databases.

End user interfaces under development:

• Client Web Interface (this client)
• JSP based web end-user interface, and associated java beans for java application development
• Add-in for ESRI ArcGIS 8.x products on windows.
