Simple digital libraries
The design of Digital Library Systems (DLSes) has evolved overtime, both in sophistication and complexity, to complement the complex nature and sheer size of digital content being curated. However, there is also a growing demand from content curators, with relatively small-size collections, for …

Secure Digital Libraries
Digital libraries are an integration of complex computer and information systems that could benefit from a formal approach to design. There are various design aspects to consider in a digital library; a crucial aspect is security. Security often is a requirement in digital libraries that should be …

Open Digital Libraries
Digital Libraries (DLs) are software systems specifically designed to assist users in information seeking activities. Stemming from the intersection of library sciences and computer networking, traditional DL systems impose library philosophies of structure and management on the sprawling …

Digital libraries and middleware technology
Digital libraries deliver personalized knowledge directly to their users, without being restricted to the contents of a physical library. In a digital library information from any online source can be managed and shared, making more knowledge available to users than before. The information sharing …

Cloud computing for digital libraries
Information management systems (digital libraries/repositories, learning management systems, content management systems) provide key technologies for the storage, preservation and dissemination of knowledge in its various forms, such as research documents, theses and dissertations, cultural …

Buckets: Smart Objects for Digital Libraries
<p>Discussion of digital libraries (DLs) is often dominated by the merits of various archives, repositories, search engines, search interfaces and database systems. While these technologies are necessary for information management, information content and information retrieval systems should …

Lightweight Federation of Non-Cooperating Digital Libraries
… and issues faced in federating heterogeneous digital libraries (DLs). The objective of this research is to demonstrate the feasibility of interoperability among non-cooperating DLs by presenting a lightweight, data driven approach, or Data Centered Interoperability (DCI). We build a …

Federating Heterogeneous Digital Libraries by Metadata Harvesting
… and issues faced in federating heterogeneous digital libraries (DLs) by metadata harvesting. The objective of federation is to provide high-level services (e.g. transparent search across all DLs) on the collective metadata from different digital libraries. There are two main approaches to …

Customisable abstract representation layer for digital libraries
… underlying functionality. Within the domain of digital libraries modification to the interface layer, to make it more appropriate for target users, requires substantial programming skill. This research studies the possibility of making a user customisable interface system by using HeI …

5SGraph: A Modeling Tool for Digital Libraries
The high demand for building digital libraries by non-experts requires a simplified modeling process and rapid generation of digital libraries. To enable rapid generation, digital libraries should be modeled with descriptive languages. A visual modeling tool would be helpful to non-experts so they …

Applying the 5S Framework To Integrating Digital Libraries
We formalize the digital library (DL) integration problem and propose an overall approach based on the 5S (Streams, Structures, Spaces, Scenarios, and Societies) framework. We then apply that framework to integrate domain-specific (archaeological) DLs, illustrating our solutions for key problems in …

Integrating Community with Collections in Educational Digital Libraries
… items related to a given course topic within a digital library will help educators in finding quality educational material. Content quality is important for users. The results of popular search engines typically fail to reflect community input regarding quality of the content. To disseminate …

Klink Search: Enabling Exploratory Browsing Activities in Digital Libraries
Complex search tasks within academic digital libraries go beyond simple lookup. They are open-ended, multi-faceted, with ill-defined information needs, requiring cognitive processing of the encountered information and learning. Academic digital library searchers often use exploratory search …

Event Based Retrieval From Digital Libraries Containing Data Streams
… is to study the issues involved in building a digital library that contains data streams and allows event-based retrieval. “Digital Libraries are storehouses of information available through the Internet that provide ways to collect, store, and organize data and make it accessible for search, …

Multimedia Content-Based Indexing and Recognition in Digital Libraries
"Recognition of digital media is more prevalent in today’s computer culture than ever before. The advent of low cost storage has created a seemingly infinite amount of metadata on the internet, as well as on local machines throughout the world. It is more important than ever to have the capability …

Investigating users’ mental models of traditional and digital libraries
… on mental models and on the usability of digital libraries, however there is no previously published literature on users’ mental models of either traditional or digital libraries. This is surprising, since many digital libraries are difficult to use and it is not immediately clear why. Our …
