A multiple view system uses two or more distinct views to support the investigation of a single conceptual entity. Many such systems exist, ranging from computer-aided design (CAD) systems for chip design that display both the logical structure and the actual geometry of the integrated circuit to overview-plus-detail systems that show both an overview for(More)
The overall goal of the Stanford Digital Library project is to provide an infrastructure that affords interoperability among heterogeneous, autonomous digital library services. These services include both search services and remotely usable information processing facilities. In this paper, we survey and categorize the metadata required for a diverse set of(More)
The recent explosion of on-line information in Digital Libraries and on the World Wide Web has given rise to a number of query-based search engines and manually constructed topical hierarchies. However, these tools are quickly becoming inadequate as query results grow incomprehensibly large and manual classification in topic hierarchies creates an immense(More)
We review selected technical challenges addressed in our digital library project. Our InfoBus, a CORBA-based distributed object infrastructure, unifies access to heterogeneous document collections and information processing services. We organize search access using a protocol (DLIOP) that is tailored for use with distributed objects. A metadata architecture(More)
The interface presented in this paper has been designed for tasks like Task 3. We refer to these tasks as information-exploration tasks. More precisely, these are tasks in which users look for new information within a defined conceptual area. The overarching conceptual area may be at any level of granularity. For example, the conceptual area may be as broad(More)
In a distributed, heterogeneous, proxy-based digital library , autonomous services and collections are accessed indirectly via proxies. To facilitate metadata compati-biity and interoperabiity in such a digital library, we have designed a metadata architecture that includes four basic component classes: attribute model proxies , attribute model translators,(More)
The Stanford InfoBus is a prototype infrastructure developed as part of the Stanford Digital Libraries Project to extend the current Internet protocols with a suite of higher-level information management protocols. This paper surveys the five service layers provided by the Stanford InfoBus: protocols for managing items and collections (DLIOP), metadata(More)
