“…The term "bucket" is borrowed from Michael Nelson's research on digital library architecture [39]. The bucket is the glue that holds the CUGIR Metadata Sharing Project together because it enables identifier persistence across the heterogeneous metadata surrogates of CUGIR records that are distributed in the OPAC, OCLC's WorldCat, CORC, and OAI.…”

Technical Service departments throughout libraries today are increasingly in the position to create and maintain non-MARC metadata that may be shared among institutions. The Cornell University Geospatial Information Repository (CUGIR) Metadata Sharing Project is an example of a system that manages heterogeneous metadata such as MARC, Dublin Core, and Content Standard for Digital Geospatial Metadata (CSDGM). The mechanics and policies required to exchange MARC records are mature and well understood. In contrast, non-MARC metadata resource sharing is largely uncharted territory. The authors present and discuss the mechanisms they implemented to enable heterogeneous metadata sharing. Now that CUGIR geospatial metadata records are widely distributed, searchers who might not otherwise have access to geospatial information can more easily discover what they need.

“…In the SODA model, complex digital objects called "buckets" provide an interface to their contents, enforce terms and conditions, and generally assume all functionality required by the user to access the heterogeneous data stored within the object [22] [23].…”

We describe the integration of smart digital objects with Hebbian learning to create a distributed, real-time, scalable approach to adapting to a community's preferences. We designed an experiment using popular music as the subject matter. Each digital object corresponded to a music album and contained links to other music albums. By dynamically generating links among digital objects according to user traversal patterns, then hierarchically organizing these links according to shared metadata values, we created a network of digital objects that self-organized in real-time according to the preferences of the user community. Furthermore, the similarity between user preferences and generated link structure was more pronounced between collections of objects aggregated by shared metadata values.

“…This influenced the OAI philosophy that it should be as simple as possible to be a DP and SPs should bare the burden of any complexity. Lastly, the UPS was also used as a demonstration for the SFX reference linking service (5) and "bucket" digital object technology (6). This emphasized the focus of providing services on metadata harvested from other archives.…”

Better interoperability through the Open Archives Initiative

The Open Archives Initiative (OAI) is an evolving protocol and philosophy regarding interoperability for digital libraries (DLs). Previously, "distributed searching" models were popular for DL interoperability. However, experience has shown distributed searching systems across large numbers of DLs to be difficult to maintain in an Internet environment. The OAI is a move away from distributed searching, focusing on the arguably simpler model of "metadata harvesting". Perhaps the strongest and distinguishing feature of OAI is its simplicity: by being "smaller" than previous interoperability projects , it actually allows for more powerful and adaptable configurations and deployments. Key concepts in OAI include the separation of responsibilities of "service provider" and "data provider" and the use of community−specific metadata sets (with Dublin Core as a lingua franca). This paper gives a brief history of the OAI, an examination of the protocol itself, and lists some of the current projects and future directions.
