AB: Strategies for interoperability have been an underlying theme in the development of the SIOExplorer Digital Library. The project was launched three years ago to stabilize data from 700 cruises by the Scripps Institution of Oceanography (SIO), scattered across distributed laboratories and on various media, mostly off-line, including paper and at-risk magnetic tapes. The need for a comprehensive scalable approach to harvesting data from 40 years of evolving instrumentation, media and formats has resulted in the implementation of a digital library architecture that is ready for interoperability. Key metadata template files maintain the integrity of the metadata and data structures, allowing forward and backward compatibility throughout the project as metadata blocks evolve or data types are added. The overall growth of the library is managed by federating new collections in disciplines as needed, each with their own independent data publishing authority. We now have a total of four collections: SIO Cruises, SIO Photo Archives, the Seamount Catalog, and the new Educators' Collection for learning resources. The data types include high resolution meteorological observations, water profiles, biological and geological samples, gravity, magnetics, seafloor swath mapping sonar files, maps and visualization files. The library transactions across the Internet amount to approximately 50,000 hits and 6 GB of downloads each month. We are currently building a new Geological Collection with thousands of dredged rocks and cores, a Seismic Collection with 30 years of reflection data, and a Physical Oceanography Collection with 50 cruises of Hydrographic Doppler Sonar System (HDSS) deep acoustic current profiling data. For the user, a Java CruiseViewer provides an interactive portal to the all the federated collections. With CruiseViewer, contents can be discovered by keyword or geographic searches over a global map, metadata can be browsed, and objects can be displayed or scheduled for download. For computer applications, REST and SOAP web services are being implemented to allow computer-to-computer interoperability for applications to search and receive data across the Internet. Discussions are underway to extend this approach and establish a digital library at the Woods Hole Oceanographic Institution for cruise data as well as extensive submersible and ROV digital video and mapping data. These efforts have been supported by NSF NSDL, ITR and OCE awards.
