Abstract
Achieving interoperability between digital libraries and visualization tools is a difficult

problem. To solve this problem, a version of the Open Archives Initiative (OAI) Protocol

for Metadata Harvesting called VIDI is proposed. It is a lightweight protocol, which

contains only 5 request verbs -- Identify, ListMetadataFormats, ListVisdataFormats,

ListTransformers, and RequestResultSet. It is extended from the OAI protocol, which

enables its simplicity and wider acceptability. It is flexible, which avoids a rigid

architecture in implementation. It is general, so it can apply to all kinds of Visualization

Systems and Digital Libraries. But most importantly, it reaches our goal of enabling

operability between Visualization Systems and Digital Libraries. The protocol design

and implementation details are given. Two prototype systems are implemented to

demonstrate the above features. Implementation details are given about ENVISION-ODL

and ENVISION-MARIAN. Analysis, evaluation, and conclusions reinforce the

discussion of the benefits of VIDI.
