An Open Collaborative Virtual Archives Environment

General information

Description

The CYCLADES system online

The standards defined by the Open Archives initiative (OAi) provide uniform access (by defining a gatherer interface) to open, heterogenous and distributed digital archives. The CYCLADES project developed several services on top of the OAi standard that support single users and user groups in their work with OAi conform archives. These services include information retrieval in distributed archives, searching and browsing in mulitlevel hypertext, collecting relevance feedback and on-line annotations, and user profiling.
