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.
