The management of intellectual content in a digital environment (Internet) requires the existence of persistent, reliable unique identifiers for each distinguishable piece of content, and associated services activated by these identifiers to manage access and other rights. The digital object identifier (DOI) is a major initiative from the content industries which is now being implemented widely. The DOI is a unique identifier of any piece of intellectual content (in any form), together with a system for using that identifier to locate digital services (on the Internet) associated with that content. This paper describes as separate strands the approach of the technology and the content communities, and how these have been brought together in the DOI initial implementation (as a reliable location tool) and future implementations of other services. The DOI has strong support from many quarters, and is funded by a not‐for‐profit independent foundation.

There is an active effort by major libraries in Taiwan to offer integrated searching as part of their information services. The purpose of this paper is to report a low‐cost and high‐flexibility system, < LIPS‐DOI>, which can carry out integrated searching with respect to resource management.

The paper first reviews the related techniques and then designs an integrated search system based on the concept of resources management. The reported system, < LIPS‐DOI>, is composed of three modules: enumeration module, description module, and resolution module. The various digital contents are first imported into < LIPS‐DOI> and thereafter the system is put into operation.

A low‐cost and high‐flexibility system for integrated searching can be implemented and put into operation. In addition to digital objects, physical objects could also be managed and searched in the proposed < LIPS‐DOI> system. This system will redirect users to the original system in which these physical objects reside.

Due to the nature of management, registered users have to manage their own objects using the features provided by < LIPS‐DOI>.

Such a system will empower library end users to find materials of mixed formats residing in disparate locations from a single interface. It was also designed with an eye toward integration with its DOI counterpart in the future.

This paper aims to describe the digital object identifier (DOI) system, an implementation of the Corporation for National Research Initiatives handle system, where a handle is designed to provide an efficient, extensible, and secured global name to an intellectual object.

Explains the overview of DOI system, its components with examples in addition to benefits of DOI to user communities.

The management of intellectual objects in a digital environment such as the internet, which is flooded with various kind of objects like research articles, e‐books, electronic theses and dissertations etc. requires the existence of persistent, reliable identifiers for each distinguishable piece of content and associated services activated by these identifiers to manage access and other digital rights. The DOI is the essential part of the electronic publishing especially for the management and the access of the resources is concerned. The DOI system is the new technology developed for persistent identification and interoperable exchange of intellectual property on digital networks.

This paper offers a useful explanation of DOI and their implementation in simple way for the professionals.

To describe the evolution of a content management system at the University of Maine Library that would function as a universal, extensible metadata repository, thereby eliminating the need to build separate databases for new digital collections, and facilitating both end‐user access and the management of electronic resources in an integrated technology environment.

Beginning with the development of a prototype system that mapped EAD encoded finding aids to a relational database, this paper discusses the evolution of this prototype into the design and implementation of a RDBMS (and continuing development of an object‐oriented database management systems (OODBMS) system) to actively manage digital objects and associated metadata. The key to the system design is metadata: extracting and mapping, transforming, and managing the processing of MARC‐based metadata into non‐MARC schemes to build digital collections. Other relevant CMS architecture issues discussed are the design of a functional bibliographic structure and utilities for metadata harvesting and indexing.

Provides information on the use of the Dublin Core Abstract Model and a flexible and adaptable collection‐centric approach in the overall CMS architecture as implemented on a non‐MARC RDBMS, and provides an explanation of the advantages of an object oriented database system over the complexity of evolving relational database tables.

A useful source for the development of an in‐house CMS, and a contribution to the growing body of literature about the transformation of MARC‐based metadata for database design.

This paper is a case study of actual work conducted at the University of Maine Library. The RDBMS manages digital collections; the OODBMS manages digital video and other multimedia resources.

This paper aims to present the semantic content identifier (SCI), a permanent identifier, computed through a linear‐time onion‐peeling algorithm that enables the extraction of semantic features from a text, and the integration of this information within the permanent identifier.

The authors employ SCI to propose a mechanism for simultaneously checking the authenticity and degrees of similarity between different information objects, and present an empirical investigation of the method. A management scenario for the control of the authentication process and the detection of the degree of violation of documents is proposed.

Such a mechanism could be adopted as a component of libraries' strategy for the protection of the copyrights for documents published on the web.

The use of the proposed numeric code can be utilised efficiently as a constituent part of the digital object identifier (DOI) system, making its computation more efficient and meaningful.

The identifier proposed in the paper can result in a more efficient index for identifying and retrieving objects in a digital library, as well as online repositories and commercial applications that can handle information retrieval requests more effectively.

Recent initiatives in digital library research have suggested new models for the creation and organisation of digital information and its dissemination to virtual communities. PEN‐DOR (the Pennsylvania Education Network Digital Object Repository) is a digital library designed to provide access to the collective experience of teachers, students and administrators in public schools in building lesson plans and using curriculum materials. Using the WWW as a platform, PEN‐DOR incorporates current research in digital libraries to provide K‐12 educators with access to multimedia resources and tools to create new lesson plans and presentations, and to modify existing ones. Design problems addressed by the project include the design of a distributed, object‐oriented database architecture, the description and cataloguing of multimedia objects, and issues related to usability and training for a geographically scattered user community. Two critical aspects of the organisation of this digital library are the development of a method for the persistent identification of resources, and the design of a record structure based on recent developments in metadata. Resource identification has been achieved by adopting a system‐wide approach with an upgrade path to the emerging URN standards. In designing a record structure, the PEN‐DOR project has elected to use the GEM (Gateway to Educational Materials) metadata standard developed as part of the GEM union catalogue project. Content for the database is solicited from project partners, government agencies and educational resources Web sites, as well as from participating teachers. Once incorporated in the repository, materials can be organised in frameworks that form the basis for lessons, tutorials and presentations. As frameworks are developed, used, critiqueed and modified, they will form a community memory of past experience. Supported by the state’s Link‐to‐Learn programme, the system will function as a resource for educators throughout Pennsylvania.

This article aims to describe the state of the art of bibliographic identifiers used in digital libraries.

A model with seven layers is used to define the scope of the identifiers that exist within the digital library field.

Based on an analysis of the identifiers a conclusion is drawn that many new identifiers must be developed in order to cater to the growing needs of libraries and other organisations involved with creation and dissemination of publications. Also, traditional identifiers must be modified in order to make them more suitable to the needs of electronic publishing.

A useful overview of the work of international standards bodies in the area of identification of digital objects.

A universal licence plate for published content, which can steer enquirers to the copyright holder — that is the idea behind the Digital Object Identifier system, which has now completed its initial trials and looks set to become as established in online content as ISBNs and ISSNs are with print.

The purpose of this study is to investigate the concept of digital preservation and traditional preservation per se and discusses various issues related to long-term preservation in a digital environment.

The study attempts to look into the various aspects of preservation in context of digital objects (borne or digitalized) especially. Bundling of an object (digital), digital storage, quality control and risk preparedness are some of the pointers studied to perceive an overall scenario for long-term preservation of an object.

Various methods have been suggested to deal with the issues related to long-term preservation of an object which can be used to frame an organization’s policy for long-term preservation.

The study emphasizes on collective measures incorporating traditional and digital means to ensure long-term preservation. It lists down various checklists to deal with various issues pertinent to long-term digital preservation.

The purpose of this study was to identify the digital curation practices in institutional repositories (IRs) in South India.

A voluntary survey was conducted among the IR managers of 23 South Indian IRs, and the response rate was 87%.

This study found that the active participation of South Indian IRs was only seen in a few digital curation activities. However, of the 33 digital curation activities analyzed, the active participation of repositories was only seen in ten digital curation activities. The performance of preservation activities was extremely low, and disagreements were recorded by the survey participants toward several digital curation activities. The most disagreed digital curation activities were emulation and cease data curation. All the participants had assigned metadata and allowed file downloads in their repositories. Raman Research Institute had provided a good number of digital curation services in their IR.

This is an in-depth study investigating the digital curation practice currently underway in South Indian IRs, and the researcher could not find similar studies in this niche.
