The document outlines the components of digital library architecture, including user interface, repository, handle system, and search system. The user interface enables interaction for both end-users and administrators, while the repository stores digital objects and their metadata. The handle system provides persistent identifiers for resources, and the search system manages indexing to facilitate record retrieval.

User Interface • User interfaceis the componentthrough which users can communicatewiththeDL system. • User interfacecan be: – For theend-users – FortheDLadministrators • Standard user interfaceis a Webbrowser. • Web browser connectsto the DLclientservices • Through theclient services, users can deposititems,browse, search and do other operations.
- 4. Repository • Repository stores and managesdigital objects and other information. • Web servers are used for storage. • The interfaceto therepository is called theRepository Access Protocol (RAP). • Repositories contain rights & permission informationapart from digitalobjects and metadata.
- 5. HandleSystem • Handlesare general-purposeidentifiersthatcan beused to identifyInternetresources, such as digitalobjects. • When used with therepository, the handlesystemreceives as input ahandle fora digitalobjectand returns theidentifierofthe repository where theobjectisstored. • Handle systemis importantto generateandmaintainpersistent links fordigitalobjectsin the repository.
- 6. SearchSystem • Search system handles indexingand cataloguingtasks. • Search system generates and maintainsindexes for various access points. • It helps the user at thebackground to retrieve relevant records from therepository.
