2 Why Talk about Digital Library Architecture?
Web bukan merupakan DL DL merupaka Commercial packages limited Flexibilitas standards (hanya pada Library) DL merupakan architecture dari Network DL merupakan pengembangan dari konvensional

3 WWW Infrastructure Evolving

Merupakan document model - digital objects Merupakan layanan perpustakaan ( library services) Menerapkan fasilitas yg lebih baik(facilities for resource discovery) Memudahkan koleksi (Flexible definition of collections) Basis manajement lebih kepada Contents dan layanan distribusi

5 Hubungan antar Digital Library

6 Digital Library Architecture: Key Principles
Open Architecture Fungsional layanan terpadu Menmanfaatkan layananan protocol jaringan Modularization Dapat menyatukan antar modul Terukur dalam dengan basis web Distribution Layanan Content terdistribusi Administrasi dan manajemen DL

7 Component- Digital Libraries
User Interface Gateway Collection Services Persistent NAMES Name Service Index Services Repository Services Digital Objects
